From The Volvo Press Kit:
"Turbo lag. If the term is unfamiliar, there’s a high chance you have still encountered this common powertrain affliction.
This is the experience with many turbocharged engines, when there’s a delay between the driver pressing the throttle and the engine responding as it waits for the turbine to supply its performance boost.
Volvo’s D5 twin-turbocharged four-cylinder diesel engine, however, features an ingenious solution. It combines an electrically driven compressor and a pressurised air tank to ensure immediate, on-demand acceleration.
When the driver requests rapid momentum by pressing harder on the throttle pedal, compressed air from the tank is released into the exhaust system feeding the turbo to quicken response.
And because Volvo’s Drive-E powertrains are engineered to deliver efficient power, the PowerPulse technology is a performance benefit that doesn’t come at the expense of fuel consumption.
The D5 twin-turbo diesel engine with PowerPulse is currently available on Volvo’s 90-series models, including the XC90, S90, and forthcoming V90 Cross Country."

NEW VIDEO EVERY WEDNESDAY! 
Авто/Мото
Remember when Volvo was synonymous to simplicity and reliability?
As a previous owner of a 240 and current owner of a 140, I agree. Still, it's cool to see the company is still relevant and innovating.
It all went downhill when they got taken over.
Jurre Volkers by ford..... Don't forget that.. But with the Chinese money now, at least we're seeing boats load more innovation
I'm starting to think that Obama and him making a law saying 50 mpg for cars was really about forcing more people to ride public transportation. Basic simple affordable cars will be no more
My Volvo S60R despite being very complex has been way, way more reliable than my newer CPO Mercedes SL550. My next car will be a NEW Volvo. I could have bought a new Volvo for what I paid for my CPO Mercedes SL550. There is also statistical data from Warranty Direct (largest British extended warranty company) listing Volvo engine's in the top 5 for reliability even ahead of Lexus at the time. BMW, AUDI, VW engines were all in the bottom 10 for reliability. Warranty Direct keeps detailed statistical records of engine faults since they are on the line financially to pay for repairs for customers.
You should have mentioned the supercharger on the T8 engine only works below 3,500 rpm. An electromagnetic clutch disengages it when the turbo makes enough boost on its own.
Correct. Didn't mention the specific RPM, but mentioned the supercharger is used at lower RPM, while the turbo handles higher RPM. They've done this in the past as well with non-hybrid versions using the same engine - ruclips.net/video/zVx-YcviGYY/видео.html
Oh great. Another part that can fail.
A Volvo mechanics nightmare.
Christ imagine diagnostics on that thing.
I'm a Volvo mechanic, and were already rebuilding the "power pulse" system on warrenty becuase it's faulty already lol
Mathias Gj, How much better is it working with new Volvos, especially when they got the Auto-Service mode, compared to mechanical analog cars?
ZEDreality cool
ZEDreality Fun and challenging, but to be honest there's not much of a difference
Well that engine is going to be a mechanics nightmare !
Andrey Arkashin or ya know a mechanics wage for the next 10 years
im a volvo only mechanic and the new T8's are really easy to work on to be honest. plus they are new so rust isnt a problem yet either. tho it takes ages to read the car, unless u have a cord on ur obd
Mechanics should be happy, it means they have still work to do.
Clicked the video as soon as i read Volvo in the title.
Z4G yeaa me too
And ofc, its a video by Engineering Explained on top of that!
+1 :D
but one thing is missing.... the 5th pot !!!
so sad we won't see him anymore... :(
lol yep
Bbbbbbut does Volvo still use clutch cables that break in the middle of busy intersections at the most dangerous possible time
how volvo try to eliminate turbo lag: add compressed air
how bmw try to eliminate turbo lag: add 4 turbo (bmw 550d) lol
the m550d has 4 turbos to eliminate boost threshold. the turbo lag is actually eliminated by other things.
Audi use an electric compressor in the SQ7 TDI, so maximum torque is available from pretty much idle.
Tony x How American brands eliminate turbo lag: not using turbos in the first place.
American brands eliminate turbo lag by having no power in the first place.
lol true, because THERE' S NO REPLACEMENT FOR DISPLACEMENT BECAUSE MURICAAAAA
:P
Always helping me learn more, clearly explained and interesting. Thank you for your time and effort!
Great graphics! Made the video very easy to understand
That was the most awkward ending ever lmaoo
Good technology more headache at repair shop .
That's putting it mildly!
It will be quite a headache when there is a leak somewhere on that tank-to-turbo line.
They'll probably patent it so only they can use it, so we wont see it on other cars any time soon.
I'm a Volvo mechanic, and the power pulse system is already faulty so were rebuilding it on warrenty
Rimac, nio or delta motorsport es very superior, four stroke is shi* is to want to improve what is already deficient. And more maintenance cost.
Soapy water u can find leaks fearly quick no big deal
As a mech. engineering student, I must say this is fantastic. Simplicity and functionality coming together!
Great animations and visuals. Thanks for sharing!
Hahaha the end though I was like wtf!!😂😂😂
All of this sounds great.....until it needs to be fixed.
I was sent.
The message is:
God loves you so much,
he didn't spare his own son(John 3:16)
that died for your mistakes.
He is not religious.
He isn't about religion.
He wants a relationship.
He wants to be your friend.
If you'll accept him.
I learnt it that way.
We all have our own beliefs
and that's why we have to trust the only usable source: The HOLY Bible.
He didn't put a bunch of rules you have to follow,
It was people that did.
Those are false.
Only way you can come to God
is you coming to his son.
His only begotten son died on the cross of Calvary,
For YOU.
So you may come to God
and to heaven
to be with him.
God *focuses on the individual*
you are that one today.
He loves you so much,
He created you,
He shaped you,
He formed you.
Why don't you accept his love today?
All you have to do
is to come to the cross
Ask Jesus for forgiveness by saying you're sorry.
That's where the journey of passing from death to life begins!
Full of future blessings for you.
The Bible says "do not let your hearts be troubled, for I am your God, I am Here to give you a future and a hope"
Wow perfect timing. Yesterday my wife and I were at the mall and they had 4 Volvo's on display. I thought they were beautiful and well designed. They feel really comfortable, too. Let's just say I want one now. When I read the specs and I was suprised to see a supercharger with a turbocharger. What an amazing machine! All I gotta do now, is test drive it. Great video like always!
Thank you for these videos! Keep up the good work! I enjoy them!
If you cannot afford a Ferrari but always wanted a Ferrari maintenance bill, Volvo has something new for you....
Baerchenization true dat
Na my 740 has 300k and still kicks ass and my xc90 has only had to be repaired once due to alternator being bad
That's not actually true. I had a 850 T5 Volvo and the Volvo dealership took like circa 400 euros for timing job with out a water pump. That's not bad at all if you think about all the space (which it don't have) and all the crap you need to get out of the way lol
Baerchenization haha warranty warranty
Then buy a BMW snd you will see s high maintenance bill
You could make a video about the new Audi TT Clubsport Concept with its twin-charged engine. They use an electric supercharger to eliminate turbo lag. Also a pretty interesting concept.
Thanks mate...your videos are always top
Awesome video Jason.
The Outro was the highlight of the entire video 😀
Why not sending the compressed air directly into the intake manifold to compensate the lag instead of spooling the turbine?
thats a good question though
That would be way more complex thing to setup. You need a certain amount of air to fuel so you would need to control amount of air you send depending on multiple factors.
I think, you would need a bigger tank for that. If I am not mistaken, this device only helps to overcome turbos moment of intertia.
Well, a couple reasons I can think of, but it's an interesting thought for sure! First, it's not passing through an intercooler, so the air is going to be hot, not great for combustion. Second, it's not really that much air. The idea is to simply get the turbine wheel spinning, where it then takes over and provides ample boost. Third, it may be a bit awkward for easily controlling air/fuel ratios if you simply inject super high pressure for a very brief moment.
Yea y not str8 into intake after a pressure regulator. Abit redundant to pump into exhaust
quick maths on the whiteboard!
Good stuff! really excited for the Polestar1 now
This video was a gem!! Best explanation 👌👍
How noticable is it? Would this be a good aftermarket addon to an custom twinscroll turbo setup?
But it doesn't have 5 cylinders
Volvo Brad I’m sad to see that as well. I drive two five cylinder Volvo’s, but I’m happy to say that the new fours still have plenty of character to them just like the old fives.
in the video it is written to a be a 2.4 litre. sadly it is just a 2 litre :S
But it works fine ^^
I can totally relate :D 2.4i v50...
Animation on point!!! Well done
I really like the way you explain things!
I've always wondered why cars have never used an onboard air compressor as forced induction for full throttle application.
They do. That's what a supercharger or turbocharger is - an onboard, engine-driven air compressor.
Yep, you can also do this with an electric motor that spins the turbo initially before there are sufficient exhaust gases, but Volvo found this to be a more cost effective method to achieve similar results.
koenigsegg did that with a freevalve engine
because you won't nearly have enough volume in that small air compressor tank to fill up the cylinders with pressurized air, it's better to just use that stored energy to drive the turbine.
He meant electrically driven...
I dont get why they dony just add a BLDC motor to the turbo. You could use it as a generator when cruising , you could use it to spool the turbo , or disconect it AND use the turbo as a turbo. Is there any downsides that i am not looking at?
yes, at the RPM of a turbo, the brushes would last about 2 minutes, and there would be so much commutation noise you wouldn't hear anything on the radio.
jayxtreme6 agree, but bldc dont have any brushess. BLDC (brushless DC) have permanent magnets , and can handle very well high rpm. Ofcourse , the design of the turbines may be a Litle different, so the propeler wont have to spin as fast as 150krpm
Turbo requires a huge amount of power to spin up, hundreds of amps from 12V. While that is not a problem for modern BLDCs and ESCs, existing 12V system just can't do it. It is, however, possible with 48V system. But that does require either a separate 48V system, or a complete move from 12V to 48V, which is too complicated, as every tiny piece of electronics would have to be redesigned. Even car fuses will not work with 48V.
Maybe for cost + reliability reason. They use the hybrid-Turbo tech in F1. In this case, To power the Turbo's e-motor, you'll need a good reliable battery (or super capacitor) which should handle continuous charging and discharging, and whole system has to be provided at reasonable price.
Maybe that's the reason BMW and now Volvo have not bothered with electrifying the Turbo.
elektrinis power=voltage x current. So just use more current. Like a starter motor. It would dip the voltage but it would be cheaper and easier because a sepparte compresor is more parts
Lag is part of the charm of a turbocharged engine. Loved it in my '89 Escort and '99 WRX.
Love a bit of lag. Makes it all the more exicting when the turbo does kick in!
I was scrolling the comments hoping to find one like minded person.
IIRC years ago Ford developed a prototype compressed air system to accelerate F150 pickups and said it could easily accelerate a F150 to 25MPH without assistance from the internal combustion engine. The compressed air was used to spin the drive shaft from my understanding. Perhaps they placed vanes on the driveshaft similar to a turbo and made it from a light weight material such as aluminum and carbon fiber?
Interesting stuff! I wonder what became of that.
Cars Simplified not a damn thing
I'll take "Expensive Automotive Maintenance" for $500, Alex.
I thought of this design several years ago, also thought about air brakes and active aero years ago. Love this kinda stuff!
Up next for Volvo in 2023 an electric hybrid 4-cylinder twin/single turbo supercharged variable pulley system 1, 2, 3, or 4 wheel drive with an option for an additional 8 cylinder diesel mounted in back for when you need to tow something. All this mounted to a 6 speed manual and a 7 speed auto simultaneously!
Makes me excited to think about having to spend $15-20,000 a year on repairs after warranty period. Nice three intake systems and two engines. Nothing could possibly go wrong with that, so easy to diagnose problems! And so easy to find a cheap mechanic to work on this!
I will stick to my BRZ.
Dorian Gray brz? Clearly you are not in Volvo target market if you're too poor to buy real sports car. The people who buy $100,000 Volvo XC90 s are not concerned with repairs I can tell you that much.
Even if I had the money, I don't think I'd want it. Supercharger does the same thing with out a fing air compressor. On top of that, highly doubt all these "rich people" buying expensive cars even know what turbo lag is. And if you are rich and enjoy cars, you're not buying a Volvo.
There seems to be a trend of car makers offering expensive luxury sports vehicles that have incredible performance, but who's value plummets after just a few years. The value goes down so fast because these beasts are difficult and costly to maintain and repair. No average person in their right mind should ever want to own one of these money pits, even a low-valued used one.
John Doe tell that to Jeremy Clarkson who literally owned one and drove his family in it for years. As far as safe, fancy, practical family-oriented luxury subs go, there's no beating the xc 90. Hence it's place firmly in the rich persons bracket for suvs.
Probably needs 6 digits to cover all the problem codes.
but will it run crysis?
Only on high settings.
This will be Crysis it self.
I Thought the video was a perfect length. Besides the quality content I can count on from your videos you explained the information well without losing my attention by being overly lengthy.
Awesome as always.👍👍
My question is for how long would the overpowerd turbo and super charged engine with hybrid live before you have to throw ton of money at it?
Not that long.
@@Petrezen1982 right after the warranty expired of course
Could I install this in my internet router?
Yes, CenturyLink will charge you a 1-time reoccurring fee of just $99.99 (increase by $4.98 monthly) to have it installed. Don't bother calling Comcast, they'll claim you already have it (and thus have already been charing you for it).
Engineering Explained Dang,I almost got scammed,thanks for heads-up
Miscellaneous Dudes OK you win lol
Most likely.
lol a 1 time fee that is reoccurring, that makes sense
THANK YOU FOR NOT TURNING A CONCISE TOPIC INTO A 10 RANT FOR AD REVENUE, YOU ARE AWESOME!!
i told you in your previous video to do volvo's e-turbo and you did it....nice :)
What happens if you floor the gas multiple times? How fast does it fill up
It would work better (in theory) with multiple charge tanks, once one is charged another starts charging.
It supercharges the air going out to minimize the time it takes for the turbo to spool, also it the tank is probably big enough for you not to notice that it's empty unless you abuse it like Bleh Tubezz said.
Tbh I quite enjoy an old laggy turbo engine. It takes skill to controll the boost.
Flooring it with a supercharger and getting instantly pinned to your seat feels way more satisfying to me, but I can admire diversity in cars and their owners. Keeps it interesting!
what kind of argument is that lol
Arend Mookhoek It‘s not an argument. It‘s an opinion.
sure, but how does it being harder to use make it better? but yeah i see why it might be fun to you. i own a volvo xc70 2007, and i really enjoy the feeling when the turbo comes on too.
Arend Mookhoek Harder is more fun. That‘s the reasons I like manuals aswell.
Nice explanation . Continue posting more awesome videos
i love turbo lag, i like when it starts to spool up and when it really gets going, you know exactly what its worth, what its doing and how much more power you get ... it also sounds amazing
I like how u end this video lol
Turbo lag is a feature!
Great explanation, thanks.
How has nobody ever done this, great video
Very informative!!
So freaking complicated, poor mechanics must hate working on these things.
pedro fernandez I hate working on modern cars in general. Have worked as a mechanic for 3 years and the only exciting that ever happens around here is when 40+ year old cars come in, which is almost never.
I just love old engineering, simple but gets the job done.
I started as a mechanic working on modern cars so I'm used to fixing them
I also started working as a mechanic 2 years ago on modern cars and I can tell you, If someday in the future you have to fix an older car, see for yourself how fast and easy it is, you even need less tools and the process in general is straightforward.
The thing I hate working on new cars is that everything is cramped, most of the time you need to disassemble things that could break just because they are in the way, there are lots of plastic pieces with rubber gaskets that aren't reusable. You need to reflect this things on the bill, customers don't like that. I have a hard time trying to explain why such a simple repair comes so expensive and they don't want to come again to the shop.
If you choose not to do or replace this little things, the repair might be compromised, the car could not run fine or even worse than before, so customers aren't happy with that and they don't come again. Either way I have a problem when a new car comes to the shop.
Most of the time, people with modern cars ask me why this or that breaks, if they are using the new car for the same purpose as the old one, and even doing the maintenance as the manufacturer says. How do you explain to this people, who bought their new expensive car with their hard earned cash, that the new car broke down just because is built worse than the old one?
Sometimes (lately more so often), people come asking me if I know of a good old second hand car that has less maintenance and it's less expensive to fix than the new one they have. These people just need a car to go to work or from point A to B, they don't need turbos, exhaust particle filters, multimedia screens, sensors for whatnot or anything that could break and cause a problem their old cars never had.
I know cars have to evolve, there's a reason a new car is different than the old one, but I think there are other ways to enhance the overall performance of a car without having to be so overly fancy and engineered.
I also can see this as a trend with all product manufacturers, not only cars, but I just wanted to share my everyday experience.
Difference between my 1959 Deville and a modern CTS is that the Deville has style and joy. There is a reason why I daily drive a 1973 Merc E-class, to avoid all the electronics, maintenance and weight. I would love to daily the Deville but gas prices are way higher now than 58 years ago in America.
BTW Luv the channel. Keep it up!!
Maaan! Bout time you did a Volvo video! They've made many innovations. I miss my S60R. Love the Audi I traded it for tho! Do a vid on Audi's sport differential that multiplies torque at one of the rear wheels in a turn!
I've got more faith in Mazda's compression ignition system.
why not hcci with turbo and hybrid?
Volvo is the most reliable and mazda is unreliable...
polychronio Mazda is very reliable they only have issues when Ford decides to try and design then
popdancebeats i have a mazda car....mazda is very unreliable...i fix computer, link, hose, radiator, etc etc after fix, again and again in every 3 months...it drives me crazy....
Drive a 2010 Mazda 3 s Sport Sedan with 160k miles. Only had to replace a burnt transmission module. $800 fix with only maintenance. Been running perfectly fine and even picks up alright.
Volvo is known for being innovarive but doesn't get alot of recognition lol.
A novel solution. Also I love the amount of "oh noes it would be unreliable!" when it is actually quite simple in design. I don't have an engineering degree like you do, but even I know how simple a simple air compressor can be. Heck you might just be able to make one with tools in a hardware store & throttle mappings of your car.
The awkward wait at the end lol. Great Video very understandable
great ideas, but how can they build this to be reliable?
+Dany test, test, and test some more. :)
the automotive industry doesnt know what the hell reliable is.
to be honest,
volvo haven't had any significant problems with these engines since 2015 ...
they did have some software issues, but they were rather quickly resolved with an update.
but the engines don't seem to form a problem whatsoever, let's see how they continue to hold up. :)
Dany Turbo + Air compressor are both unreliable and unnecessary, so if you're looking for reliability just do away without them.
Albert S. Thick block how is that going to affect reliability?
So your injecting air into the exhaust and presumably before the lambda sensor... So how are they stopping it from reading a lean situation and thus dumping more fuel in?
Well this is a diesel engine, so they run a very wide range of air/fuel ratios. It would be a bit more complex if it was gasoline, for that very reason. Diesels can regulate power based on how much fuel is injected, and run just fine at very lean ratios.
Except you'll be producing a lot of NOx.
NOx is somewhat an issue in Diesels but the point is that this technology doesn't affect that since a Diesel doesn't have a lambda sensor and the maximum amount of fuel injected is determined by the air mass sensor (in the intake).
PbPomper No, it's well known that with Lean AFR (most diesels) the NOx emissions are very low compared to a Stoichiometric AFR .
UpShiftTrackdayVideos
They could also have an input to the computer when the air is being relesed aka activated, the computer can be programmed to expect a change in lambda reading a bit like how they do for the secondary air injection system
Great video! Thank you for sharing your knowledge. Is that a dual stage air compressor?
The latter part of your video reminds me of the old Golf 5 GT with a turbo and supercharged engine. While I think the concept is cool to help mitigate turbo lag in a sense and maybe add a little sportiness to the Volvo brand, the extra added cost for these components, should one fail would be a turnoff for me. Also the added cost to the overall MSRP of the vehicle when you look at purchasing new. Although I don't call Volvo's a high end luxury car, I think this may push prices to more than what people would be willing to possibly spend on a Volvo. Especially if the performance doesn't match up to a car of similar price, especially if you look at the V90.
You produce some great videos, so please keep up the great work.
My Name You have a good point, although, considering recent Volvo depreciation, one of these would probably be a screaming bargain in a few years as a used car or CPO.
That is a good point about being a CPO car.
Good thinking from Volvo to add a compressor
I wish Volvo could eliminate North Korea.
???
HAHAHA
Or better yet, USA.
sithlordsoup North Korea eliminates whole Sweden with their pee. Sweden is only 9million
Albert S. North Korea will eliminate itself. There will be a revolution elentually. Keep it peaceful. Let the locals sort their own problems out
Always love watching your videos. They answer questions I ask myself all the time. I'm extremely into automotive engineering and am only now realizing that I should be an engineer. The good thing is I'm going to be entering college again soon, but what do I need in order to become an engineer? I'm strong in math just need to refresh myself. I have always built cars and learned all the engineering aspects myself and understood them well before I had ever had hands on. My father always worked on cars with his hands so I have a good grasp of hands on and also a brain primed for being schooled in engineering, I think it would be a very good combo and I also think I have already waited too long to decide to do this. Any pointers you have for me? I was either doing this or computer programming, and while I know computers are much more guaranteed than cars in the state their in now, I still have much more passion for the inner workings and designs of automobiles than computers.
Yung Padawan Get a Mechanical Engineering degree. Insanely broad so you can go into whatever field you want. Cars? Sure. Manufacturing? Yep. Tooling? You know it. Heavy machinery? Absolutely. Aerospace? Yessir.
@EngineeringExplained is there a possibility you can do a video or series on trucks: specifically Chevy/GMC, Ram, and Ford. You could touch upon the Diesel variants Cummins, Duramax, Powerstroke. Maybe picking out the fallacies and doing some mythbusting amongst those who choose one company's truck over another while choosing your favorite based on criteria you've used in the past to choose a preferred car. You could even get into the gasoline versions as well. It would be very interesting.
Your videos are great. Keep up your hard work!
Great, one more expensive thing that will fail.
Not that expensive if you think about it from a manufacturing standpoint.
You have calculated proof that it would fail? Or have you worked on it personally?
Arjun Bhat Its more moving and working components thus making a higher likelihood of something failing. Think before making a comment
Hahaha yeah well they don’t really care past warranty.
Jonathan Stewart
How about making one more reliable, volvo??
Steve Jones volvo is the most reliable in the world??
thats to much technology for them lol
volvo makes the most reliable cars in the world...
*Volvo used to make the most reliable cars
This is what I was thinking of when burning some late night oil. I'm glad it's already beeing implemented
last 15 seconds is golden :)
Can you explain why when u compress air into lets say a air tank it becomes cold, but when a turbo compress air into a combustion engine its creates heat. Ive always wondered this. Im a scuba diver and when u let out the air from the scuba tank is freezing since its compressed. Hope u see this
air in =hot
air out=cold
It becomes hot (warm) when you fill a scuba tank and increase the pressure.
The cold comes when you release the air again and thereby reduce the pressure.
They 2 methods you referred to are opposites. Compressing air = hot air & uncompressing air = cold air
+carlos caro When you compress air into a tank, it does indeed build up heat. When you release pressure from a tank, the air cools while dropping from high pressure to low pressure. Same thing happens with paintball guns, you’ll notice the CO2 tank gets super cold as you play. The tank gets super cold from changing from a high pressure liquid state inside the bottle, to a low pressure gaseous state outside the bottle. I don’t know much about scuba, but their may be a phase change occurring as you transfer air into your tank, which could make it cold. Can also witness this with a gas grill, the propane tank will get cold as you cook, as it releases pressure.
Air going into a scuba tank is also heated by being pressurised. It simply bleeds that heat away into the atmosphere over time through the tank walls until it reaches around ambient temperature. Later, when you start using the tank, you decrease the internal pressure, which lowers the temp further, giving you that cold air you're used to feeling. In an engine, it's _constantly_ being compressed and heated as the engine uses whatever the compressor supplies...so the heating becomes more noticeable, as it never gets much time to bleed that extra heat off into the atmosphere (other than briefly as it passes through the intercooler.)
Who liked the video before they watched it?
D'awww, thanks guys!
I liked it as soon as the picture was displayed. The idea of using an accumulator to ameliorate turbo lag has been around for awhile, so I'm glad to hear the issue materialize.
Liked the comment before I read it.
But did you share it on a Dodge salesmans page before too? Lol....just to show how Volvo will own the market in 10 years or less....just my guess.
Simple and ingenious!
I thought of this type of thing and someone told me volvo do it haha
Nice vid ☺
whats important to Volvo owners is having the ability to jump right out into traffic right in front us just to drive 10 mph below the speed limit and without that instant power you could miss out on annoying someone thats trying to get somewhere
the best turbo lag reduction is to use 6+ litre V8 instead of 2 litre I4
some people dont want to buy that much gas...just money for greedy opec and big oil
And get less power and torque out of the v8 than the i4
You hate cars don't you?
Who? Me ?
turboing both.. wat?
Literally had this idea before, but I wondered what issues would come with the increased backpressure
Don’t forget to mention that if you have a Turbo and Supercharged vehicle, of your Turbo is big enough, at higher RPMs it back drives the supercharger and the PSI generated by the Turbo now drives the screws on the compressor and the parasitic drag normally incurred by a supercharger’s belt now becomes power because the pulley is now being driven rather than dragging the crank down.
Super cool phenomenon you only see in twin-charged Vehicles.
I like trains
ASDF reference. I see you.
Choo choo!!
Stutututututu
Haven’t they been doing this with nos for awhile now?
Nitrous oxide doesn't fix turbo lag
s i d e w a y s l i f e s t y l e I don’t remember the name of the company but there’s been a kit out there for a while that injects no2 into the cold side of the turbo to bring it up to speed it may just be a drag car thing to help cut down 60ft times I’ve even seen it done with a bottle of regular compressed air
Never heard of it, don't think it's common either tbh, if it even exists.
Very cool. Pneumatic booster for turbo.
The sound of a turbo spooling up is cool. Nothing like easing into the throttle while it does its thing and then mashing it. I just like to feel the added power come on and put me in the seat more I guess.
(Almost) First
Volvo isn't the first to use electric motors along with gasoline engines as a means to increase fuel economy and performance.
StrangeClouds I think the prius popularised that, as much as people love to hate it.
He didn't day that, they've been doing it for years
thanks captain obvious
Lol nobody said they did
ok
Love your videos🔥Props to you💯💯!
Pretty smart use of the stored air. By increasing back pressure, its affect is multiplied by the increased pumping energy from the engine's exhaust.
How bout just don't use turbos lol.
but mah psssssssshhh tsu tsu tsu
turbos turbines and compressors are great technology why not use them?
StrangeClouds bit what about baaaaap stutututututu and the spool up sound and the speed when it kicks in
In a diesel, turbos are essential to performance, and almost no diesels are made without them. As compression engines, the turbo helps with the compression of exhaust gases and allows the engine to produce significantly more power than a naturally aspirated diesel.
Yeah that would really make coold diesel engines.
That is a very sophisticated animation
independent and rechargeable NOS for the intake! Smart!!!
Now this is exciting!
You remind me of Leonard Nimoy (Spock) with the eyebrow lift ;-)
Fascinating, well done Mr EE :-)
Live long and prosper!
Well... I understand that in racing application turbo-lag is bad, but when you're cruising around just for fun, I think that floor it, wait a second and then "feel" the power and torque kicking in is priceless. Another example can be in cars like a Single-Turbo Supra or any powerful car with high turbo-lag when someone challenge you and you both floor it, he starts to gain and with you at firts nothing happens but than the boost kicks in and you troll the opponent saying goodbye...
P.S.: sorry for the grammar, I'm italian
This is one of those interesting implements that we've all thought was too silly to do before. Add all the rest of the goodies, and it's already pretty daring.
I feel like I saw an article a few years back talking about a similar set-up with the pressure tank feeding the intake side instead of the exhaust. Did anything become of that?
Cars Simplified I don't think you can get much benefit by pressurizing the intake manifold of a car that uses forced induction. But maybe that's not what you were suggesting.
In some marine engines, this system is used to prevent black smoke on starting and of course sudden changes in load. In a car this must have this benefit too and prevent damage to the Catalytic Converter by unburnt fuel.
Great way to overcome the lag.
Cool eyebrows play from nerdy guy!
