It's an interesting effect, when organizations/people/companies try to reduce carbon footprint. It's good that they are trying, and needs to be done, but it then seems to highlight all the other aspects of the business that have carbon footprint that you normally wouldn't think about.
I think the idea is less focused on making the series more eco friendly and more focused on the development of green tech that will eventually be used in regular cars.
@@PG-20 I guess you never worked in motor sport… some people there fly whole 747 / 380 size planes just for one person, while they could do just perfectly fine in (much faster by the way) Gulfstream jet which uses fraction of the fuel.
We would have to go back to the 80's and earlier to do that,---when we were free to use the engines we want. I make a living modifying 2-stroke engines,---and I will be the last one. Anybody who thinks a 2-stroke engine is going to make any kind of a comeback---has been sleeping for the last 25 years.
Considering the amount of engineering potential we have today, I think 2 stroke engines still have a lot of life left in them. One of the recent advances is the new 2 stroke doesn't need pre-mix to run anymore.
@@Enonymouse_ …they haven’t needed pre-mix for a very long time…reservoir of 2-cycle oil…that mixed with the gasoline. As a kid I had a late ‘70s Yamaha 2-stroke motorcycle and never had to mix…just fill the oil reservoir.
2 strokes are incredibly good engines when engineered properly and their benefits are only enhanced by these awesome new E-fuels. Long live the 2 stroke engine!
@@Risnstonks Not really all that much. A good fuel injected 2-stroke can be more efficient than a 4-stroke. And since the oil is electrically mixed, the pollution caused by that oil is lowered. I haven't seen catalytic converters for 2-strokes, so it's hard to compare it with a 4-stroke.
A good 2 stroke is always gonna be better for the displacement, as long as fuel emission and economy aren't concerns. Plus it would make it very exciting as a lot of 2 stroke development has halted so it would be amazing to see what would happen with 2 strokes with F1 money thrown at it. Shame we won't see it
@@Matthew-yc6nx no, for a 2 stoke that is run for the same amount of time as a 4 stroke, the 2 stroke will have roughly twice the amount of power stokes, meaning almost twice the amount of fuel used

At this point the FIA is so stringent in its regulations, that a different, less-restricted, open wheel Motorsport class that could be used for engineers to go all out in all areas would be more interesting than what F1 has become.
And who would be funding this “balls out” engineering approach? Who is paying for that beryllium alloy engine? Who is paying for those two dozen aero-plasticity winglets? And….so on. The answer is: NOBODY. Formulas exist in racing for a reason mate. So you have an “interesting” formula on paper but no money to build it. Nice one mate. I guess you could transform the drawings in to CGI and use an existing gameplay engine to develop an esports thing. Or you could just have a wank and play Forza on your Xbox.
@@Lailas776 it would definitely be grassroots like you’re saying, but you have to look where formula 1 has come from How did it start. Also, a lack of massive funds would breed cost effective innovation. And the lack of regulation would allow more routes to be used.
As diesel two-stroke engines work very differently to petrol two-stroke engines, you really could create an F1 two-stroke engine if it uses the two-stroke cycle used by diesel trains. (Hint: it uses a looooot of forced induction and forced exhaust) Ferrari didn't remotely do it first. :)
Detroit diesel 2 strokes also had an oil sump, a pressurized intake via blower and exhaust valves. And they were some of the most prolific diesel engines for there time(and sound wicked too)
@@mayorwrenchmcgnome hell yea, I work on a oil well servicing rig, the one I work on now has a detroit 60 series but the first rig I worked on had a non turb 8v71 and I miss that sound. The 60 series is a really good, basic reliable Power Plant (sounds good, pretty much just loud turbo noises, we all wear hearing protection on the job site so a service rig dosent have much for a muffler so it's pretty loud but it has no personality like the 8v71 and such do)
It’s time to introduce the Diesel engine I guess. For fuel, just use frying oil from Mc Donald’s and all the other places that fries stuff. The whole track would smell fries and it would be awesome
I mean it would be badass to have a c9 two stroke i don't think it would move cause the only cars in the world are two strokes im not meaning to be a downer but im not sure about two stroke c9
One in two diesel locomotives in the US built since 1939 used a two stroke diesel with forced induction via a roots blower or turbo (with clutch so that it operates as a radial supercharger at low RPM to keep scavenging going), direct fuel injection, sump lubrication and exhaust ports. And in the 10 thousands of these engines were exported or powered ships and stationary equipment. They were made by a GM division called EMD and are still in production up to this day, and the engines have evolved a lot since 1939 with variable geometry turbo's and EFI, but are still based on that original design from 1939!
I'll say this, I'm fairly confident the engineers working for F1 will overcome a majority of the issues with the efficiency of a 2 stroke engine. Given enough money and time, these guys have performed miracles us silly RUclips watchers could only dream. They'll awe us all with their ingenuity.
I also wonder if they'll eventually quit trying to make it tech relevant to road cars. We all know the future of performance is electric, so either F1 will go electric to stay relevant to that, or they'll just say screw it and stick with the loud visceral combustion engines fans love without trying to relate it to road cars that don't use them anymore.
@@quillmaurer6563 that's pretty presumptuous to say that the future is electric when currently, they both have significant drawbacks. Every infrastructure is based on a liquid based fuel right now and it's not easy to just turn a wrench and install plugs when most of them are proprietary. It would take decades to switch the infrastructure to all electric. That's why hybrids are a more viable option.
@@tt7hvn idk if you noticed, but electricity is, literally everywhere. Hybrids are dumb, expensive battery yet still expensive to maintain the ICE engine.
@@sebastianflynn1746 idk if you know anything about how electricity works but you can't just plug an EV into a wall socket. ICEs are not expensive to maintain, lol. They're expensive to maintain if you own an F1 engine. ICE laughs in Honda engine longevity. However, I'll give you this, if you literally know nothing about engines they're not expensive to maintain. If you have to pay someone every time you need an oil change, just turn in your man card. Both vehicles will need maintenance regardless of the power source. They'll both need alignments, tire rotations, bushings will wear, suspension will deteriorate, the engine is just a component of a vehicle. It's become so accepting that vehicles are disposable....just throw it away and buy another one. I take pride in making mine last given it's age. Because hey, it's cheaper to maintain it than buy something new 🤷
Your not “donating” at omaze. Your playing an online lottery with extremely out of proportion odds of winning and in the end only a tiny bit of your money actually goes to help. The majority goes straight to omazes pockets. That’s a really shady company y’all are partnered with there.

That's music to my ears. My first bike was a two-stroke Moto Beta. Next was Yamaha. But the advantage of the 4-stroke is that it has better power in the lower RPM range and that is probably why Honda's 100cc engines did so well. Ok, this is back around 1969/70. We were so free then.
@Bob Watters I've literally been to multiple formula 1 races and indicar races and they both use V6s and sound great. not the same obviously but still amazing
The craziest thing is, as a kid when I learned about how Detroit Diesel 2-strokes worked, I wanted to take that architecture shrink it down and make an F1 engine.
@@thatboomhauerguy5601 what peaked my interest in them was in the early 80s my Grandpa took a 4-53 and swapped it into a 1978 Dodge W200 with a 2 speed rear end.
12:00 I think you mean to say, "Ferrari solved the problem by copying Diesel engine Technology from 1938!" The only difference here between a Detroit Diesel, and the F134 is displacement, and Fuel type lmao.
true however an opposed cylinder 2 stroke free valve engine with scavaging blower and separate forced induction with direct injection is far more complex but in theory efficiency increases are huge as are power per liter.
I'm interested in these 2 stroke improvements making their way into hybrid vehicles. Using electric for low end torque to supplement an efficient, high rpm, easily produced engine would make a lot more sense than adding electric motors to a hellcat (which will be coming).
Unlikely. Two strokes probably won't pass emissions. They're so against 2 strokes, the largest two stroke you can drive on the street legally is 80cc (.08 liters) IIRC.
@@trashbandit2449 and the epa has cracked down so hard on small engine manufacturers in the last decade or so. the reason why people have so many problems with carburetors now is because the passages are so small to limit fuel consumption and emissions. then you add fuel that pulls moisture out of the air. and things get clogged. there's just a huge push for everything to go electric. we'll see silent F1 races before too long.
@@anester1866 already have E1. Formula 1 has already gone to smaller engines, no way were ever going to v10 or 12, and definitely not 2 stroke. They switched to turbo 6 because it's more relatable with the car market,since they're owned by car companies. To go two stroke... almost every manufacturer on earth would also be powered by a two stroke, and with environmental regulations, that can't happen. Personally I'm not going to waste my time supporting bringing two strokes into the market, too busy trying to get people to keep gas engines in general around. Everyone wants electric, they don't realize that some of us want more than just transportation. Ban the EPA
Hybrid is the future, EV is wishful thinking hopes and dreams. Technology trickles down from aerospace, aeronautical and F1. Currently non of the above are EV with zero future of them becoming solely EV. Technology just isn't there, probably a century plus away. People forget EVs have been around before IC engines. They're not efficient, safe or relatively cheap to make. Every EV made is done at a loss, please understand that's not how a successful business is run. That's big government talking.
Id love to see a 2 stroke, 3 cyl (6 piston) turbocharged, opposed piston Achates engine, powered by liquid hydrogen or carbon neutral synthetic fuel with a beefed up ERS deployment. I could imagine them being mounted boxer style for low COG, retaining their stressed nature rather than employing a spaceframe, revving at insane RPM speeds with no valvetrain to worry about and being very durable to the point of 2-3 engines per season. It'd represent something quite useful to the future car industry in developing H2 or synthetic fuel.

there's already a 2 stroke supercharged production engine that existed, it was first made in the early 40s, sounds like Ferrari copied some cues from the old Detroit diesels that were 2 strokes
Well, the Ferrari engine really was a measily excuse for a 2 stroke engine. I mean, look at the power it produced, every GP500 2 stroke would have outclassed it by a long shot.
@@mandernachluca3774 Yeah the supercharger in the Ferrari/diesel design creates a lot of parasitic loss, adds weight, and complexity. At that point you might as well just make a four stroke.
As a qualified mechanic you explained it way better than my college teacher. Should be doing education videos for real mechanics. With your teachings young mechanics would be eager to learn and be well informed. Great job 👏
"Clean" 2 stroke engines have been around for decades... as diesels. The Commer Knocker was a flat 3 cylinder 6 piston opposed design from the 1950's, and the Detroit Diesel 2 strokes powered trucks for over 50 years. Cummins is developing a 1000bhp, flat 4cyl 8 piston opposed, twin turbo, supercharged diesel. These designs could easily be adapted to petrol, and Koenigsegg's Free Valve tech would make them crazy efficient with clean exhaust.

In 1980, a number of Yamaha Bike Race engineers were seen at Ferrari. It was denied at the time, but has since been admitted. You mentioned that less power will be required from the IC engine and more from the electric side. That will be the death knell for F1. No-one likes the sound of the current V6 turbos and most would welcome a return of the best sounding F1 engines, the V10s.
@Bob Watters what are you talking about every serious dirt bike manufacturer still makes 2 strokes. they died because they stink and if your pump goes out your engine eats itself also no one wants to rebuild their engine every 10 hours
Which I don’t understand since with a separate piling system, direct injection, and a blower like an old Detroit I don’t see how it would make anymore emissions than a 4 stroke engine
@Bob Watters they are still alive, a friend of mine bought a New 2020 two stroke just this year. The thing is all full of emission stuff. Gotta take that out….These things need to smoke.
nope you are wrong. The oil burnin trick was done by every engine manufacturer of current F1. Ferrari most likely used to relatively low refresh time of the fuel sensor to burn extra fuel between its refresh cycles.
They can for sure design and improve 2 stroke to make way more efficient and powerful than anything before it and actually prove the theoretical projections comparisons to 4 strokes
You forgot to mention 2 stroke engines have issues with heat dissipation, because they have a combustion phase every time the piston is at TDC. A 4 stroke has a 'cool stroke' on the intake stroke when there is no combustion taking place. This effectively cools the piston crown, cylinder and valves. This also increases efficiency and the longevity of the engine. This issue also effects Wankel rotary engines, their combustion chamber sees no 'cool stroke' either, which is why rotary and 2 stroke engines exhaust manifold and tail pipe is always extremely hot, and also why they have issues with cooling.
In the dirt bike world, you will almost never see a 2 stroke bike over heat, but you see 4 stroke bikes over heat all the time, and people have to add fans to the 4 stoke radiators to help cool the bike down. Same sized radiators on both types of bikes... Just sayin..
Two stroke engine needs half of the fuel of the 4 stroke engine. Because every time when piston goes down its making power, in exhaust and intake piston is free fire, but all forces are applied
A perfected 2 stroke would make more sense for hybrid electric vehicles as it would have the highest power to weight which would mean the vehicle would be lighter and the engine will take up less space
@@afhostie Nope. The oil burning can't be avoided with a rotary like it can with a 2 stroke. That alone kills them. Rotaries also produce much more heat due to friction, meaning they're less efficient.
The oil-injection bit is the least-high-techy bit of KTM's setup (and pretty mainstream from the 70s until most two-strokes left the market throughout the 90s). The means of *feeding the fuel*, however, is the Big New Deal here. What this means for two-stroke engines in general remains to be seen.
Would've been cool to hear about some more modern cleaner 2 strokes like what BRP does in etec engines. Oil injection, Reed valves, an turbo 2 strokes from the factory. They're doing pretty cool stuff. They also make the only 2 stroke outboards anymore (I think)
@@GT-mn3bx ya know when you said 2.5 I thought you meant the old Black Max that everybody tunes lol. You mean the ProXs…!? Yea they still make those …. Just very few.

Toyota did this in the 1980s using a traditional head. It needed a very capable ECU direct injection and a supercharger. It worked but it was stupidly complex expensive unreliable and thirsty. It didn’t solve any problems they had at the time. Also the power density was 50% higher not 100% as expected
Engine tech in the snowmobile world has been moving towards that setup for a while, and we're now starting to see direct injected turbo two strokes from the factory. I always thought turbo two stroke sleds would always remain an aftermarket novelty, but now you can get one off the Polaris dealer's show room floor!
I'd like to see a engine designed like the old Detroit diesel engines, 2stroke diesel, with valves, 2-4 valves per cylinder, the intake is at the bottom of the cylinder, and they scream when you get on the throttle! Just imagine one with a better cam, bigger valves, ported cylinder sleeves, running a huge intercooler, with about 60psi boost, with a light weight crank rods and Pistons, a light weight block and head, using the most efficient supercharger, plus dual compound turbos, like a 8-92, =92 cid x8, Nearly 750cid, even a hotrod version of a 6-v71 or inline 6-71 , 71cid per cylinder! Running 4-6 bar boost with cool air! Maybe make a gas, or nitromethane/methanol version, direct injected , a 4340 crank , titanium rods, light weight forged Pistons, a light weight billet flywheel, a light weight timing chain to replace the heavy gears, it's only $500k to get started, maybe a 24v-92! 24cylinders at 92cid each cylinder! 😎, And that only the next to largest engine, they also have one over 100cid per cylinder, of two stroke diesel power,!!
When talking about 2-stroke engines, one must clarify the distinctions between a crankcase scavenger design from a forced induction design. Engines in 2-stroke motorcycles and weed wackers all use crankcase scavenging. Engines like large diesel buss engines (Detroit diesel) are 2-stoke that use large blowers/supercharges, often paired with turbo chargers, to scavenge the exhaust out of the cylinder with out using the underside of the piston for scavenging.
fun fact: you can drastically change a 2 strokes power band even with the same expansion chamber by just using spacers before the expansion chamber. a longer pipe will pull harder down low and a shorter pipe will pull harder up high. i believe its due to the fact that the shorter pipe gets the pressure back to the exhaust port quicker hence holds the air fuel mix in better at higher rpms, the same logic applies the other way. when at low rpm and the piston takes longer to move up and down, the longer exhaust will have a delayed pressure wave holding in the air fuel mixture better when piston speed is lower. just my 2 cents
@@olileoli2788 yes. That's the point. A rotary will never be on the road with modern emissions regulations. A 4 stroke would be too heavy for a real Rx. But a 2 stroke....

My father worked for Chrysler at the Huntsville Alabama plant as a electrical engineer. Back in like 88-89 they had a "Open House" where you could see airbags being blown up with slow motion high speed video of them, new cars, electronics of all sorts, and several prototype cars. One of them was (I kid you not) a prototype Dodge Shadow 2 stroke turbo. Don't ask me how, why or anyway how it all worked, as I know how 2 strokes work and at the time I was just a kid and my dad remembers the car and powerplant but doesn't remember anything about how it was setup. So Chrysler was playing around with 2 strokes as well back in the late 1980's.
Yeah makes allot of sense for a hybrid, and the sound, even boring hybrid road cars could sound awesome.. Changing up everything we base ICE vehicles around could be a way to discover more efficient ICE systems too.
Just when I'm starting to think "god I've lost him..." there's always this "AHA!" moment when everything is falling into the right place. Awesome explainer, thanks!
I thought about this as well. This engine design uses a wet sump, transfer port induction, a blower and direct injection. It also ads a simple barrel valve to the exhaust port to allow for asymmetrical exhaust timing (can close exhaust port early enough on the up-stroke to allow time for the fuel to atomize before the spark, but then open the exhaust port early enough on the downstroke to allow the cylinder to clear out before the fresh charge of air comes in. Keeps the simple construction of the 2 stroke, and ads only a simple barrel valve shaft down one side of the engine. Would save a LOT of weight on a V-6 or V-8 engine, and with no reciprocating parts pushing against springs, the exhaust barrel valves would be very reliable and require relatively little energy to operate. Further, this design would save space by making the expansion chamber un-necessary. Video is 3D printed mock-up. Roots type blower would be better at low revs than centrifugal blower shown, due to the pressure of a centrifugal blower rising with the square of the speed. ruclips.net/video/5s3OJUyJJJs/видео.html
The engineers didn't because it's not allowed by section 5.9.2 of the technical regulations, where it states: "Variable valve timing and variable valve lift profile systems are not permitted." On top of that they probably want to not increase the complexity since a current F1 power unit costs somewhere between 10-11 million USD, whereas the car costs roughly 13-14 million USD (with the PU included).
My trimmer has a four-stroke engine ... Edit: the Detroit Diesel ... 4-valve two-stroke, blower scavenged, old school at this point. The "blowers" have evolved to sit atop every NHRA nitro car.
Large capacity high HP 2 strokes have been around for a long time. Outboard Marine Corporation produced 3.5 litre V8 2 strokes for the F1 Powerboat series in the early 80's. They were producing north of 500hp over 40 years ago. The sound they made running at 9k to 10k rpm was incredible, Whilst I'm sure you're right and it will never happen, it would be amazing to see what a modern 2 stroke built with modern materials and techniques and an F1 budget could achieve!
Do you live under a rock? The Rotax voice coil direct injection 2-stroke engine has been used by Skidoo for more than a decade to power their snowmobiles. They even make a turbo-charged version. Up until about a year ago Evinrude was producing the E-TEC 2-stoke for their outboard motors
They just need to give him a 20 minute video to do whatever he wants. Just once. Characters, techno dancing in whatever the fuck he wants to wear, bald caps, everything.
when i was in school learning to be a car mechanic i designed an engine that was two-stroke with direct injection that won't scavenge exhaust in the intake its not so hard to design i was 16 then
Balakai8, It's been done, it's called the Rotax ETEC direct injection 2-stroke engine that Skidoo has been using to power their snowmobiles for over a decade.
Check out the Rotax E-TECH - 800cc and 160 bhp. Skidoo snowmobiles use them with less weight and better fuel mileage than equivalent (1200cc) four stokes. Fuel is injected after the ports have closed so there is no smell. Rotax even have a turbo version for use at high altitudes. Exhaust has a variable height valve to give a wider power range. Inlet has reed valves to prevent blow back. Fuel is not run through the crank case so less oil is needed to keep the bottom end happy. Its also possible (with a small blower) to have a wet sump where air and fuel never goes into the crank case. This works well with V and Cross format engines.
I can only really talk from a motorcycle racing pov as I am more into bikes than cars. But the only two drawbacks from 2-stroke engines was when racing them was getting the air/fuel mixture right and they were more likely to seize if you ran them too lean. Hence why you always had your hand over the clutch all the time in case it seized and the back wheel locked. But they were quicker and the smell of a 2-stroke is just heaven.
2 stroke engines are for generators or AC converters for electric motors. No battery's so low weight, no loss of range or power etc. Just big gas powered drills stuck on a hot wheels.
Completely unrelated to whether it has a battery. It makes power on every down stroke instead of only half like a 4 stroke. This presents scavenging (exhaust out, fuel air mix in) challenges because there is no down stroke not making power to have a negative pressure and pull in fresh air and fuel. Many small engines use the back side of the piston going down to create a positive pressure to fill the cylinder. This is why they have no crankcase oil, and use mixed fuel and oil. With a supercharger or a turbo, this is not needed.
Awesome vid man, I am an old " stressing old" 2 stroke performance guy . Now direct injection, super charged induction, oil sump and valves in the head you are describing an old Detroit diesel system LOL. But the fact of 2 strokes, there is 25-30% less torque compared to a 4 stroke, a less major fact these days is the RPM, 4 strokes have almost the same rpm as the 2 stroke but given the 2 stroke weight is lighter. But torque is the king, hp is the queen. The king moves the mountain in one shot very slow, the queen takes small chunks faster, but the mountain gets moved with in the same time frame. rpm X torque divided by 5252 = hp. Two strokes need to develop a little more torque instead of relying on weight and RPM.

A good 2 stroke is always gonna be better for the displacement, as long as fuel emission and economy aren't concerns. Plus it would make it very exciting as a lot of 2 stroke development has halted so it would be amazing to see what would happen with 2 strokes with F1 money thrown at it. Shame we won't see it

At this point the FIA is so stringent in its regulations, that a different, less-restricted, open wheel Motorsport class that could be used for engineers to go all out in all areas would be more interesting than what F1 has become.

And who would be funding this “balls out” engineering approach? Who is paying for that beryllium alloy engine? Who is paying for those two dozen aero-plasticity winglets? And….so on. The answer is: NOBODY. Formulas exist in racing for a reason mate. So you have an “interesting” formula on paper but no money to build it. Nice one mate. I guess you could transform the drawings in to CGI and use an existing gameplay engine to develop an esports thing. Or you could just have a wank and play Forza on your Xbox.
@@Lailas776 it would definitely be grassroots like you’re saying, but you have to look where formula 1 has come from How did it start.
Also, a lack of massive funds would breed cost effective innovation. And the lack of regulation would allow more routes to be used.
As diesel two-stroke engines work very differently to petrol two-stroke engines, you really could create an F1 two-stroke engine if it uses the two-stroke cycle used by diesel trains. (Hint: it uses a looooot of forced induction and forced exhaust) Ferrari didn't remotely do it first. :)

4 strokes don’t completely separate their intake, and exhaust cycles. There’re is a thing called overlap. Which is actually very important.

Wrong

@@grievuspwn4g3 it's not accidental lmao, it gotta mix to work properly
What is overlap? Can u explain in simple terms? I though an intake and exhaust phases in 4 strokes are happening separately?
One in two diesel locomotives in the US built since 1939 used a two stroke diesel with forced induction via a roots blower or turbo (with clutch so that it operates as a radial supercharger at low RPM to keep scavenging going), direct fuel injection, sump lubrication and exhaust ports.
And in the 10 thousands of these engines were exported or powered ships and stationary equipment.
They were made by a GM division called EMD and are still in production up to this day, and the engines have evolved a lot since 1939 with variable geometry turbo's and EFI, but are still based on that original design from 1939!
I'll say this, I'm fairly confident the engineers working for F1 will overcome a majority of the issues with the efficiency of a 2 stroke engine.
Given enough money and time, these guys have performed miracles us silly RUclips watchers could only dream. They'll awe us all with their ingenuity.
I also wonder if they'll eventually quit trying to make it tech relevant to road cars. We all know the future of performance is electric, so either F1 will go electric to stay relevant to that, or they'll just say screw it and stick with the loud visceral combustion engines fans love without trying to relate it to road cars that don't use them anymore.

2 strokes usually don’t have valves in the cylinder head. They have a reed valves (ktm v-force4 is a good example) which makes them so simple

"Adding a sump and valves introduces complexity", yea, but it's still less complex than a 4 stroke ;)

@@trashbandit2449 and the epa has cracked down so hard on small engine manufacturers in the last decade or so. the reason why people have so many problems with carburetors now is because the passages are so small to limit fuel consumption and emissions. then you add fuel that pulls moisture out of the air. and things get clogged. there's just a huge push for everything to go electric. we'll see silent F1 races before too long.
@@anester1866 already have E1. Formula 1 has already gone to smaller engines, no way were ever going to v10 or 12, and definitely not 2 stroke.

To go two stroke... almost every manufacturer on earth would also be powered by a two stroke, and with environmental regulations, that can't happen.
Personally I'm not going to waste my time supporting bringing two strokes into the market, too busy trying to get people to keep gas engines in general around. Everyone wants electric, they don't realize that some of us want more than just transportation.

Hybrid is the future, EV is wishful thinking hopes and dreams. Technology trickles down from aerospace, aeronautical and F1. Currently non of the above are EV with zero future of them becoming solely EV. Technology just isn't there, probably a century plus away. People forget EVs have been around before IC engines.

@@trashbandit2449 2 strokes already pass emissions. Bought my son a 2021 TE250i, fuel injected and oil injected and yes EPA compliant.
Id love to see a 2 stroke, 3 cyl (6 piston) turbocharged, opposed piston Achates engine, powered by liquid hydrogen or carbon neutral synthetic fuel with a beefed up ERS deployment. I could imagine them being mounted boxer style for low COG, retaining their stressed nature rather than employing a spaceframe, revving at insane RPM speeds with no valvetrain to worry about and being very durable to the point of 2-3 engines per season.
It'd represent something quite useful to the future car industry in developing H2 or synthetic fuel.

Sounds a little too much like 'oral' to me. Especially when he's talking about engines being dirty.
You forgot to mention 2 stroke engines have issues with heat dissipation, because they have a combustion phase every time the piston is at TDC. A 4 stroke has a 'cool stroke' on the intake stroke when there is no combustion taking place. This effectively cools the piston crown, cylinder and valves. This also increases efficiency and the longevity of the engine.
This issue also effects Wankel rotary engines, their combustion chamber sees no 'cool stroke' either, which is why rotary and 2 stroke engines exhaust manifold and tail pipe is always extremely hot, and also why they have issues with cooling.
Yes, and we should never eat too many calories, smoke, drink, use drugs, associate with wayward women, gamble or drive over the speed limit.
@@johnnyquist8362 or run near the pool. cant forget that one
In the dirt bike world, you will almost never see a 2 stroke bike over heat, but you see 4 stroke bikes over heat all the time, and people have to add fans to the 4 stoke radiators to help cool the bike down. Same sized radiators on both types of bikes... Just sayin..
Two stroke engine needs half of the fuel of the 4 stroke engine. Because every time when piston goes down its making power, in exhaust and intake piston is free fire, but all forces are applied

The oil-injection bit is the least-high-techy bit of KTM's setup (and pretty mainstream from the 70s until most two-strokes left the market throughout the 90s). The means of *feeding the fuel*, however, is the Big New Deal here. What this means for two-stroke engines in general remains to be seen.

When talking about 2-stroke engines, one must clarify the distinctions between a crankcase scavenger design from a forced induction design. Engines in 2-stroke motorcycles and weed wackers all use crankcase scavenging. Engines like large diesel buss engines (Detroit diesel) are 2-stoke that use large blowers/supercharges, often paired with turbo chargers, to scavenge the exhaust out of the cylinder with out using the underside of the piston for scavenging.

@@autodidact537 Now scale that up to a 600CID 10L v8 for a BB Etec 2 stroke!
fun fact: you can drastically change a 2 strokes power band even with the same expansion chamber by just using spacers before the expansion chamber. a longer pipe will pull harder down low and a shorter pipe will pull harder up high. i believe its due to the fact that the shorter pipe gets the pressure back to the exhaust port quicker hence holds the air fuel mix in better at higher rpms, the same logic applies the other way. when at low rpm and the piston takes longer to move up and down, the longer exhaust will have a delayed pressure wave holding in the air fuel mixture better when piston speed is lower.
just my 2 cents
I imagine you could further improve 2 strokes with modern E tech. Can you imagine Mazda bringing out a new cheap little Rx, but with a 2 banger?
bots are stealing your comment
But an rx is a rotary
@@olileoli2788 yes. That's the point. A rotary will never be on the road with modern emissions regulations. A 4 stroke would be too heavy for a real Rx. But a 2 stroke....
@@Vok250 good point.
@@Vok250 rotary is 2 stroke but better, and its emission problems would be solved with turbocharging and direct injection just like for the 2 stroke.

If F1 plans to move to a more electrified future, wouldn’t the higher power to weight ratio of the 2 stroke engine be better?
No cuz they’re trying to be carbon neutral . How does going to a 2 stroke engine move in that direction
@@fastballfilms4214 who gives a f
@@fastballfilms4214 - Burn only fuels derived from above-ground sources, and the car is carbon neutral. Just like you when you breathe; as long as you’re not eating fossil fuel, your body is carbon neutral.
@@fastballfilms4214 Dont care abt carbon restrictions in F1 they make little difference to the world. Implement them on road cars but keep that shit away from racing. I just want good sounding engines in F1.
@@bottomtext593 It does make a difference. Race cars are years ahead of market cars. Of course eventually the market implements some of the tech they use when the cost to make it is more affordable. If F1 keeps using non renewable energy, what good would that be for the market? I think it would only slow the transition to green energy and reduce public market innovation in the future.
y’all make learning about cars so fun
I apologize on behalf of the Asian community
Two-strokes smell so good. That’s why I love snowmobiles and a lot of boats.
Bring back 2-strokes in MotoGP... The sound and smell of my childhood, sitting trackside at Phillip Island.
**sniiiiiiffff** yeah
My father worked for Chrysler at the Huntsville Alabama plant as a electrical engineer. Back in like 88-89 they had a "Open House" where you could see airbags being blown up with slow motion high speed video of them, new cars, electronics of all sorts, and several prototype cars. One of them was (I kid you not) a prototype Dodge Shadow 2 stroke turbo. Don't ask me how, why or anyway how it all worked, as I know how 2 strokes work and at the time I was just a kid and my dad remembers the car and powerplant but doesn't remember anything about how it was setup. So Chrysler was playing around with 2 strokes as well back in the late 1980's.
To answer the original titles question of "Is F1 Switching to 2-Stroke Engines"
No homie, they is not.
Maybe a good idea though idk.
I got really excited at the thought of these amazing engineers building the best two stroke possible
“Are you tellin me we should all be two strokein here” was my favorite skit by far 😂😂😂
It seems like hybrids would benefit from a smaller, forced induction 2 stroke
Yeah makes allot of sense for a hybrid, and the sound, even boring hybrid road cars could sound awesome.. Changing up everything we base ICE vehicles around could be a way to discover more efficient ICE systems too.
Talk about the Ski-doo Rotax e-tec 2 stroke engines! They’re know to be better on emissions than some 4 strokes
Just when I'm starting to think "god I've lost him..." there's always this "AHA!" moment when everything is falling into the right place. Awesome explainer, thanks!
Maybe 2 stroke engine better for instantly accelerate and higher rev engine
@Harum's Piit🌹 You can get a free eternity by offing yourself scammer.
I thought about this as well. This engine design uses a wet sump, transfer port induction, a blower and direct injection. It also ads a simple barrel valve to the exhaust port to allow for asymmetrical exhaust timing (can close exhaust port early enough on the up-stroke to allow time for the fuel to atomize before the spark, but then open the exhaust port early enough on the downstroke to allow the cylinder to clear out before the fresh charge of air comes in. Keeps the simple construction of the 2 stroke, and ads only a simple barrel valve shaft down one side of the engine. Would save a LOT of weight on a V-6 or V-8 engine, and with no reciprocating parts pushing against springs, the exhaust barrel valves would be very reliable and require relatively little energy to operate. Further, this design would save space by making the expansion chamber un-necessary. Video is 3D printed mock-up. Roots type blower would be better at low revs than centrifugal blower shown, due to the pressure of a centrifugal blower rising with the square of the speed. ruclips.net/video/5s3OJUyJJJs/видео.html
Im surprised F1 didn't go in the direction of free falve to create a more mechanically simply engine for 4-strokes.
The engineers didn't because it's not allowed by section 5.9.2 of the technical regulations, where it states:
"Variable valve timing and variable valve lift profile systems are not permitted."
On top of that they probably want to not increase the complexity since a current F1 power unit costs somewhere between 10-11 million USD, whereas the car costs roughly 13-14 million USD (with the PU included).
My trimmer has a four-stroke engine ...
Edit: the Detroit Diesel ... 4-valve two-stroke, blower scavenged, old school at this point. The "blowers" have evolved to sit atop every NHRA nitro car.
Bait! “Why they’re switching”
“Well actually they’re not switching at all”
Large capacity high HP 2 strokes have been around for a long time. Outboard Marine Corporation produced 3.5 litre V8 2 strokes for the F1 Powerboat series in the early 80's. They were producing north of 500hp over 40 years ago. The sound they made running at 9k to 10k rpm was incredible, Whilst I'm sure you're right and it will never happen, it would be amazing to see what a modern 2 stroke built with modern materials and techniques and an F1 budget could achieve!
Do you live under a rock? The Rotax voice coil direct injection 2-stroke engine has been used by Skidoo for more than a decade to power their snowmobiles. They even make a turbo-charged version. Up until about a year ago Evinrude was producing the E-TEC 2-stoke for their outboard motors
Just imagine a 16,000 rpm two stroke engine. What could have been
Absolute Beauty.
Jerry's content is absolutely hilarious. Always informative, and good for a laugh too.
They just need to give him a 20 minute video to do whatever he wants. Just once. Characters, techno dancing in whatever the fuck he wants to wear, bald caps, everything.
when i was in school learning to be a car mechanic i designed an engine that was two-stroke with direct injection that won't scavenge exhaust in the intake its not so hard to design i was 16 then
Design and execution are 2 different things
@@nicoesko1956 if i have money and time i could make it
Balakai8, It's been done, it's called the Rotax ETEC direct injection 2-stroke engine that Skidoo has been using to power their snowmobiles for over a decade.
Check out the Rotax E-TECH - 800cc and 160 bhp. Skidoo snowmobiles use them with less weight and better fuel mileage than equivalent (1200cc) four stokes. Fuel is injected after the ports have closed so there is no smell. Rotax even have a turbo version for use at high altitudes.
Exhaust has a variable height valve to give a wider power range. Inlet has reed valves to prevent blow back.
Fuel is not run through the crank case so less oil is needed to keep the bottom end happy.
Its also possible (with a small blower) to have a wet sump where air and fuel never goes into the crank case. This works well with V and Cross format engines.
"Why F1 is Switching to 2-Stroke Engines" Okay, the title was a straight up lie
Did it change?
"Why F1 Should Switch to 2-Stroke" is up there now, 60 min after dropping.
They DID change the title. Good catch. Serves me right for being late to the party.

I love 2 strokes. Amazing when tuned and engineered the right way
If it's 2 stroke engines, i seriously hope the engine regulation is freed up so maybe we'll see some flying spinning doritos??
That would be good!!
I can only really talk from a motorcycle racing pov as I am more into bikes than cars. But the only two drawbacks from 2-stroke engines was when racing them was getting the air/fuel mixture right and they were more likely to seize if you ran them too lean. Hence why you always had your hand over the clutch all the time in case it seized and the back wheel locked. But they were quicker and the smell of a 2-stroke is just heaven.
I was so excited at the prospect of 2 stroke F1 engines 😭😭😭
But I still love you J
The more engine manufacturers enter the sport the better, as they say variety is the spice of life.
2 stroke engines are for generators or AC converters for electric motors. No battery's so low weight, no loss of range or power etc. Just big gas powered drills stuck on a hot wheels.
Completely unrelated to whether it has a battery. It makes power on every down stroke instead of only half like a 4 stroke. This presents scavenging (exhaust out, fuel air mix in) challenges because there is no down stroke not making power to have a negative pressure and pull in fresh air and fuel. Many small engines use the back side of the piston going down to create a positive pressure to fill the cylinder. This is why they have no crankcase oil, and use mixed fuel and oil. With a supercharger or a turbo, this is not needed.
Awesome vid man, I am an old " stressing old" 2 stroke performance guy . Now direct injection, super charged induction, oil sump and valves in the head you are describing an old Detroit diesel system LOL. But the fact of 2 strokes, there is 25-30% less torque compared to a 4 stroke, a less major fact these days is the RPM, 4 strokes have almost the same rpm as the 2 stroke but given the 2 stroke weight is lighter. But torque is the king, hp is the queen. The king moves the mountain in one shot very slow, the queen takes small chunks faster, but the mountain gets moved with in the same time frame. rpm X torque divided by 5252 = hp. Two strokes need to develop a little more torque instead of relying on weight and RPM.
Formula one's engineering ingenuity would be good for the 2 stroke, curious to see what comes of it if anything.
