The dreams of engineers are often the nightmares of the mechanics who have to service them.
There are too few of us engineers that actually wrench ourselves, so you're right, serviceability is almost always thought of last. Unfortunately, that is unlikely to ever change.
Brilliant observation. So true.
This is also making many vehicles a major cost liability once out of warranty for the average Joe.
Most of the engineers coming out of college today couldn't engineer themselves out of a wet paper bag.
@@Rsenior1981 all we could ask for is a minimum of 6 inches all around the engine to access nuts and bolts, without the need to remove a cab or pull major components to access a few 10mm bolts. Lol.
@@generalkayoss7347 Why engineer yourself out of a wet paper bag when you could just engineer an entirely different container to begin with?
Quasi-turbine, spends $86,000 on machining internals, spends $7.95 on plumbing fittings to pipe it up...
the quasi turbine never works as combustion engine, only blow with steam or compressed air: this engine as far to much friction losses...
And therefore it is a motor and not an engine...
@Coalicious more like 800
@@brianevans1946 the non sense differenciation between engine or motor exists only in english, in all other languages it's only motor
@Brian Evans.
No... it’s an engine.
It turns heat into mechanical motion... the very definition of an engine.
A steam engine is still an engine.
A turbine engine is still an engine. A pneumatic engine is still an engine. Feel the discharge air... it’s cold.
Good content. Thank you. So little filler and healthy scepticism with a chuckle even! :D Love it! +++
I did enjoy the video. The engines shown in the video were definitely strange. I would have liked to have seen more information about the engines. All in all, very informative.
I really like it when the thumbnail is in the video nice job
No clickbait👍👍👍
Then you should check out my new channel I made @Noarth Creations, I have my new and first video out "making leather knife sheath". I would appreciate the support!
#truth 💯
Feels like a low bar. It used to _always_ be like that because you couldn’t do it another way.

that circle cycle motor had me on the edge of my seat lol
Hey man, love the video! Quick, to the point, informative.
Thank you for including as many videos as you could.
the major benefit of the Liquid Piston engine when it comes to Rotary type engines is that they have managed to get rid of the Apex points, which is a major issue for Rotary Mazda owners. By getting rid of them, they can increase the efficiency and power of the block.
It seems that there's still Apex points, just on the other side, the 3 sharp edges, but it also looks like in this design they will wear slower than a regular rotary.
Hows the oil consumption going to be though? Lol
@@JordonPatrickMears11211988 seeing the clip of the chainsaw makes me wonder if it's a straight 2 stroke. 😂
Mazda has pretty well fixed the apex points in its latest engines.
Thanks for the video bud, lmao at the way you laughed at the name liquid piston, took me a minute to get that.

I remember reading about the quasiturbine back in the late 80's in 'Motorcycle news' here in the UK.
30 years later it's still being tried...
Excellent video. Thanks
Go over a bump with No 6 Circle Cycle and everything will go with a mighty Bang !.
All clever stuff though.

Thank you for this awesome list video with 7 items that doesnt take 27 minutes to watch!
Some interesting design engines out there hopefully I get to see them one day and some of these newer cars
Wow, the cycle engine! I thought several times about a similiar concept with magnets. But I am not an engineer. :p
You're an engineer if you make it happen and it works. Maybe not an engineer on paper but who cares about that. Hopefully you try it someday. 👍

"An engineer's wet dream is a mechanic's nightmare"
I was previously unaware of your channel’s existence but I’m intrigued as ever.
You have earned yourself a subscriber
very good visualisations - great job, did you model them yourself?
the second one is really interesting. it has issues though. it'd cost a lot to manufacture and build. alignment of the chamber and piston would present great challenges for companies to be consistent. it however, looks like it'd rev extremely efficiently. especially since it combines the physics of a fly wheel into a crank shaft. but one misalignment of the piston or chamber and the thing will explode. damaging the entire engine, while most issues with normal engines are fairly salvageable.
that second one looks like it would be susceptible to alignment problems...
Heh yeah, points for originality though,.
matthew hurley - I thought the video of the open one was going to demonstrate the *_catastrophic_* failure mode that could occur with that engine... I’d not want to be anywhere near that thing... it definitely is unique tho :)
If anyone in the room even thinks about wiggle room... That thing is going to explode
I've had that happen before, rapid misalignment can result in slap to the face.
Neil Dohi - 😂🤣 It can also cause bruised equipment !!
Dude. I love all those engines. Thanks so much for the great video.
Great video beautiful 💡
I really like the concept of Ion engines although we have to find a way to make them more powerful :D
We can't. Because the energy required to accelrate ions increases almost exponentially with size.
@@harikrishnav.s.1299 Oh, I see. Yeah, I was a little younger back then when I commented ;)
@@emberdrops3892 sure. I'm not much older from when I read about ion propulsion. It's a bit above high school physics.

#5 Quasiturbine - This is very similar to a concept put forward in the early 1970s by the Rotarymotive Developments group in New Zealand. RMD was engaged in exploring various rotary concepts, many of them developed from inventions of Mr Hamilton Walker. Most of his patented concepts were based on an oval piston or stator as in this engine. This particular geometry - using a lozenging rhomboid piston - can provide consistent seal engagement between the stator and pistons but that is about all it has going for it. Otherwise it has most of the shortcomings of the common Wankel with high surface to volume, even more complex sealing grid, plus a few extras such as the varying angular velocity of the drive shaft (or the need to add a differential mechanism to take out the hunting of opposite piston pairs) and high mechanical forces at the seals which have to drive the inertia forces as the pistons rock back and forth...........9 out of 10 for complexity
Even problematic will be to design it's intake and exhaust , along with cooling systems.
@@aravindb8232 eh?
Interesting take. Appearing akin to a square rotary engine, it is my personal opinion that this design should be referred to colloquially as the scrotory engine. Partly because of the s denoting the squared-off look but also partly because it sounds like scrotum and I'm immature so that's funny to me.
@@cosmicturban2797 😂😂😂😂😂
This engine has no vibration! It is also a detonation engine opposed to deflagration engine (your regular petrol engine). I wish there would be more development on this engine.
Cool video, thanks :)
that circle cycle has a LOT of meme potential.
nice
That 2nd one looks dangerous as hell
the second one just making the infinite popping sounds lol
I love that 'pocket tanks' background music in this video.
You should've mentioned konigsegg's electronic valve engine. That thing is dope
Nah the raptor methalox engine is better.
Imagine a 4 cylinder push rod with a simple carb.
So a 35-year-old Toyota Corolla then? What about it?
Imagine a 2 stroke single cylinder engine
godyea wow are you crazy?
Imagine a flat-opposed air-cooled four cylinder engine that can be mounted in the rear of a car...
@@JBofBrisbane sounds like Nazi spawn to me

@@ghoulbuster1 the engine already exist. check out their channel. its already being tested in a pickup truck
Thank you for the great video
Yup more moving parts has come to mean "oops more to fail" and that in itself does not usually inspire buyer confidence. Opposing piston though sounds really cool.
@Юрий Тойкичев yup engine technology seems to be stuck in the rut it has been for many years.
I agree, JWST has over 500 failure points on it... but its not had a RUD or any other sub nominal performance yet.
Wow yeah this thing probably hits way harder than my zvx 18 what was I thinking
The dreams of engineers are often the nightmares of the mechanics who have to service them.
@@rommelcorpuz4157 yeah I can vouch for that, even simple stuff like putting the oil filter housing in the V of the engine, terrible idea.

Love the 2.0 Vc-Turbo on my Altima & 1.5 on the rogue. Provide nice power & efficient on fuel ⛽️
I can already see Nr. 6 exploding in spectacular (and expensive) fashion.
We need thinking like this now more then ever. Really cool.
Yaa
Damn I saw a rotary engine so I though of a new way to make an engine, then found this video and the arches 2.7 is what I was thinking of trying 😂
The achates engine design is already is popular use at Fairbanse Morse for their giant diesel engines used for ship power and emergency generator power etc... so its a proven design and extremely reliable. There is really little to no reason not to trim the fat from it and put it in automotive applications. The military is also contracting Cummins to build a 4 cylinder 1000hp tank engine using Achates technology called the ACE (advanced combat engine)... they also have a big 10L engine for freight tractors being tested by I think it was Tyson and Walmart that meets all next generation emissions requirement while also reducing the need for so much DEF.
The have been a number of opposed-piston engines in production. Perhaps the most notable is the Napier Deltic, which had three banks of cylinders of opposed pistons. It's an 18 cylinder two stroke diesel, supercharged. Used mostly for railway engines and in ships. You can read up on it here:
en.wikipedia.org/wiki/Napier_Deltic
The Skyactive engine design has been around for ages.
Think it has promise, that rotary too?
The 6 piston 3 cylinder engine is basically an evolution of the Napier Deltic, the German Jumo 205 and the Fairbanks Morse 38 8 1/8 submarine engines. Look them up, especially the Deltic, a fascinating and complicated engine.
The Liquid piston would be good for power armor where light weight, fuel efficiency and high output power is more important than engine longevity.
Having a disc like that spinning on your back would also shake your teeth out
@@halipatsui9418 Less reciprocating mass than a piston engine, so I don't think it would be easier to find a more helpful gasoline method
Heck yeah POWER ARMOR!!!
Snow White - I’d think power armor would be better served by a distributed network of energy storage devices (batteries, capacitors, whatever), rather than a single point of failure. One slingshotted kamikaze goblin to the back and your armor is out of power with the liquid piston...
What happened? Did you run out of the standard Fusion Core? Diamond City might be able to hook you up =)
Gm: yeah, just reuse the block... New heads? Sure, yeah that works. Just make sure they fit that one block we made in 1997...
Nice engines but lack of subscribers keep up the good work and maybe days months? You may gain more subs and i'm in😁
That was interesting, thanks for sharing this video
Achates 2.7 is really nice concept that way 360° blast efficiency can be captured.
It's definitely better than that Ecoboost heh. I believe the old Junkers from WW2 used the same kind of design.
Those WW2 Germans invented our world we live n Today!!!
@@Tech_Planet The napier diesel uses that principle too, tho it has been used in railroading.
If you look at marine engines used on ships, this engine design has been around for about a century. (Not really a concept, but well proven.) Displacements on those tend to be ridiculously huge even when compared to semi-trucks. (You could fit a regular car engine inside one of those pistons.) They just chug along quietly and smoothly.
Yeah, the Commer Knocker was particularly good at converting fuel into noise.
Had about 18hp (i'm joking for idiot naysayers) and consumed about the same as 400hp - most of which was converterd to the most sublime very loud noise.
A number of these have practical potential !
Like you,
I would like to see more actual hard data on them before I make up my mind.
We are a small engine repair facility, and would love the opportunity to test a few of the smaller engines in real world application !
The chainsaw, and the
Go-Kart definitely have our attention !
I like the circle cycle, and achates engine. Definitely game changing designs.
What an awesome selection of engines!
I've had an idea for a motor for the past 30 years but never did it. After watching this (and kind of expecting to see my motor) I should try to build it.
Well what happened
@@SS-ts4ht What happened after I wrote that 2 years ago? I have a better idea that I think should be mass produced. I tried making the parts but couldn't get within any tolerances so I bought a bridgeport milliing machine, south bend lathe, Jet horizontal/vertical 7x12 bandsaw and have been buying steel on Craigslist in the Pittsburgh/Cleveland area and am working towards that goal. Surprised I got asked. I don't think anyone believes I can do it. But I'm trying.
@@onenewworldmonkey good luck bro , you will definitely make it
@@onenewworldmonkey good luck to you then!
I wish I had a grip of this knowledge and imagine with the names and numbers and what each components individually do.
Excellent!!
These concept engines have been around for 30-40 years...
Except the opposing piston, thats been in production for over 100 years :p
Looking forward to the sky active X engine.
dark crusher1221 i have watched couple reviews. They say its really efficent but it has torque problems, low rpm kills all the power.
@@sirfranchiseofthefilth6791 ya. It runs a very lean fuel mixture. Meaning less power. Even with the supercharger.
Very intresting. It all depends on the efficincy and consumption for the future.
Nice video
the liquid piston rotory by simple physics is definitely a bit of an upgrade. Its basic physics. The rotor path is smoother and because it uses less forms of motion, more of an in and out AND round and round creates less dynamic internal momentum change=less momentum to change=less rptating weight+a round rotor design would seem to allow different terms of compression.
Do you have any links to forums or sites where people are actually making and testing these? Thanks.
Even mechanics are engineers themselves and they quickly pickup the defects of creators of machines
The Achates sounds like a rehash of the Leyland L60 engine the British used in their trains (where it ran at a constant RPM, and worked well) and the Chieftain tank (where its only saving grace was you could swap the engine for the spare you brought with you in three hours).
Those variable compression engines have been in Infiniti cars for 2 years... still nice video.
A good rule of thumb, fewer moving parts means better longevity. (Provided parts are made to a set standard)
As a layman, that's what I see: Too many parts, too often something is broken.
True but not always. For example a in linefour cylinder engine get better relatability with a balance shaft than without.
But there are many more important points to consider except longevity. For example turbo engines are likely more efficient than normal motors.
Rotary engine approx 16 moving parts, inline 4 cylinder approximately 100 but no comparison in reliability and longevity over a rotary 👍
@@jimdavis2385 yeah a part is a failure point, that's pretty obvious.
2:06-2:20 i thought i was having a stroke
Awesome 👍👍👍👍
The opposed engine setup is used as a train called a delta something. It’s got 3 cranks and 3 cylinders in a triangle, dunno how many in total.
... you're right. all strange, and i've only heard of 1 of them (Mazda's SkyActivX).. you get a Like, good sir
The things that Koensigg is doing is truly incredible . Check it out ! The guy is a genius ! Solenoid valve actuation , infinitely variable . He also came out recently and stated that all internal combustion engines will be ineffective in catching the quickness of the EV’s but that hybrid drives will be the best way to go until battery technology catches up . He is a man willing to see what is wrong with what he has been doing . I expect Koensigg to come out with a hybrid at some point now that he has seen what Tesla has done .
Agreed. I'd really like to see them pursue a turbine hybrid.
Chevy's solenoid actuated cylinder cancellation is garbage. Hope they can do better
Neil Dohi ruclips.net/video/S3cFfM3r510/видео.html
I can’t find anything online about Koensigg, Koenigsegg on the other hand...
They already make an hybrid, wich hold some record, like fastest 0-400-0 for a production car.
1:50 Gotta love that plumbing pipe handle.
The Duke engine is a pretty cool design. Fairly familiar. You guys should look into it.
Should make a video about new winding techniques for electric motors, new magnet technologies, transformer rectifiers, batteries or big capacitors.
We are not going to be using gasoline much longer.
Also the hall thruster was very cool.
#2 is cool, but even a small offset and it blows itself up
It would be possible to add guides with valves.
The Achates is a similar design to the old Leyland L60 or Commer "knocker" engines, or even a Doxford, being an opposed piston 2-stroke diesel engine. It's just a lot smaller than those older models.
good to see people trying to keep the rotary style engine alive
It's exciting to see engineering hasn't given up on the gasoline engines.
It is because there is no other good source of fuel or energy.
@@bond1j89 lol good one.
Is this a joke?
...which will however be extinguished, hopefully soon, I would put to the penalty those who still produce internal combustion engines
@@2sing internal combustion engines are not an inferior form of mechanical energy than electric motors. They both have similar carbon footprints and similar total emission levels from different sources. Electric motors may eventually overtake gasoline engines but both types of motors should be developed alongside each other to benefit from both. We should, however, definitely be focusing on moving away from fossil fuels as a source of energy for both power plants and internal combustion engines, as both engines use the same amount of fossil fuels. (Combustion engines don't need to use fossil fuels to burn, we have other sources of ethanol and other compounds that can work well)
The quasiturbine (No. 5) 1:32 is similar to an engine invented in the early 1960’s by Eton Rajakaruna, a friend of my father, in Hull, UK. He was from Ceylon (now Sri Lanka). He called it the “heart-beat engine”. It was featured in an article in Popular Science magazine in April 1962. He was inspired by a vague idea my father had about the possibility of containing the intake, combustion, expansion & exhaust cycles inside a bag-like vessel instead of using a piston & cylinder. Eton’s design looked very similar to the quasiturbine except the combustion took place inside the collapsible box. He was a proud man & claimed that he’d built the entire thing himself in his kitchen using minimal tools. In actual fact my father made most of the prototype parts for him & he made small changes himself. It never ran because it was almost impossible to seal the hinged corners & sides where the combustion chamber contacted the cam plates on either side. It recently struck me that it may have worked better as a steam or compressed air engine, a point that is also made about the engine in this video as well.
Cool story, bro 👍
There are some cool engines here for sure. The quasiturbine engine will probably sound really cool with a larger displacement. I agree though that it does seem a bit overcomplicated
What about the xeon ion engine? That is incredibly exciting. All these other engines would barely produce enough thrust to propel a Microsoft and probably have an ISP of 0.5 is going at max throttle.
My top three favorite new and upcoming engines by number, 6, 1, & 3.
The LiquidPiston X is going to end up having the same apex seal issues that all rotary engines have. I also have yet to see a multi-rotor LPX, as all of the ones I've seen have been single rotor with the same triangular shaped intake and exhaust; how would they design for a multi-rotor, or even a design for a more conventional intake and exhaust? Having the ports spaced around the shaft makes things more difficult, and a multi-rotor would have an odd design of intake-rotor-exhausts-rotor-intakes, or for 3 rotors it'd have to be i-r-e-r-i-r-e, and the piping for that kind of setup would be insane. What about chargers, with six inlets, and all the piping that comes with them, you'd end up needing some hefty charging equipment when compared to other engines. Wiring is another issue considering all the plugs are also located around the entire engine. Also the difficulty of machining the rotor is questionable.
There's also the fact that LiquidPiston disappeared for years, then came back just to disappear again, and last I know, nobody really knew why. Either they got a good contract, or they ran into financial issues.
Of all the new engines, outside of mass-production ones from large corporations, LPX is one that I would've hoped to see come to market and actually be decent. It'd be nice to have a modern rotary, other than being used as a hydrogen fueled range extender for electric driven hybrids, but I don't think we'll ever see one at this point. Hopefully someday LPX will have more than just a single rotor to show off, but I have my doubts.

I think the major advantage is that LiquidPiston X, can have higher (compared to Wankel) compression ratio due to geometry. And because of three combustion chambers, the temperature of the housing should be more uniform, that alone should improve seal design. So, overall it should be better than Wankel. Sure, the seals will be wearing off, but it is not that a big deal, and they can last years I guess. The biggest issue would be a lubrication of the seals, and emission issues.
The resolution to all the issues you stated above, are the same as for any Wankel... intermediate castings between rotor section to unify plumbing, and ceramic apex seals. Problem solved. NEXT!
@@driverjamescopeland the issue with intermediate castings on the lpx is how you'll route six ports to a single port for a header, the piece itself will end up being larger than the engine with that much complexity.
Also, ceramics are nothing new, you would think that, if they're effective, they would have been extensively tested and used.
In your absolutely annoying, and toxic, words: Next!
@@xaytana The improvement on the apex seal front, from LiquidPiston's own statements, is that you can cool them much more effectively because they're in the housing rather than on the rotor, which should make them last a lot longer, and because they're not moving, the tolerances can be better and require less lubrication. If this actually turns out to be the case, it could be a really useful engine.
Well, until then, we're still waiting for the interdimensional engine from Area 51 to appear.
It gets lousy mileage, we're still working on efficiency
It already has, it just ended up in someone else's dimention. 🤔
Bob Lazaar has it hidden somewhere in his underground garage, but don't tell the feds, they'll send nineteen hundred agents from twenty seven different agencies, just to look for it 🤣
At last a video that's MORE interesting than the title.
I really need to patent my magnetic induction engine with almost no wear at all!
Number 6 is a bit like a deltic engine
Some of these look like exercises in how to make an IC engine vastly more complicated (and thus, less reliable and more expensive) for a 5% or 10% gain in mass/fuel/power efficiency.

The CV four lobed epitrochoid motor could be efficient af!!! That is cool! Think it was #4 on here.
The Infiniti/Nissan engine is the best and practical.
Thanks.
The last one is just a updated rotary motor
Yes but it's a improved rotary engine.
Very interesting designs... The simplest and probably the most efficient one is the Liquid Piston engine... The power to weight ratio potential of this Liquid Piston design is also quite impressive... The Wankel Rotary engine was a very innovative design, and they had tremendous potential, but they had some serious inherent problems. The 'Liquid Piston' engine design seems to have solved all of the inherent problems of the Wankel design, with the high power to weight ratio and what appears to be extreme reliability and simplicity...
Any links to more info on actual testing besides their main website?
"Napier Deltic" is interesting. Was used in the locomotive.
The extra friction and weight of the Infiniti VC engine probably erases most of the improvement in efficiency. The extra manufacturing cost of the monkey-motion linkage makes it more expensive to build and buy, so it probably won't pay off for the user. I predict a short production run.
Nissan can't even produce a simple engine with a decent life-span.
@ale bob Fifteen years as an auto mechanic has shown me the strengths and weaknesses of every auto manufacturer. 2 years as a Nissan dealership tech made me realize that they make many of the most poorly designed vehicles available. The Nissan 3.5L V6 with its short-lived timing chain setup is quite possible the crappiest V6 engine of recent times.
Engineers also designed the Titanic and the Tacoma narrows bridge, so what is your point?
@@danielb6814 I've owned 12 Datsun 620 pickups with the L20b engines, one I put close to 300,000 miles on it before I pulled it, it was still running good but I swapped a Buick V6 into the truck, damn good little engines. I've never been into one internally cause I never had one that didn't run! Can't speak for other Nissan engines but the L20b is the best engine they ever made.

Quasiturbine: *Starts*

1:25 - that's not a running engine, it's being driven by an electric motor. It just proves you can make some things that fit together when rotating.
@Marijuana Piranha it's going "fop fop fop" which is what I'd expect the pistons to sound like when they rush out of the cylinders under external drive, not what I'd expect the explosion of an ICE to sound like.
Notice they cut away the normal spark combustion engine cylinder during the skyactive demo? That's because skyactive is almost literally the same thing just timed/metered more efficiently and works at a higher compression than a typical combustion engine. It is a step above normal combustion but that simulated cutaway veiw was the wrong way to show it because the difference is almost indefinable. It has a crank, pistons, valves (int/exh), spark plugs, works on 4 strokes, the same 4 strokes. It's not a new engine or even new technology. Hundreds of different combustion engines run the same way but with different compression/timing. Maybe it is different and was just explained improperly? But everything I see just shows a normal combustion engine
It is a normal combustion engine. While I certainly have issues when they call it a compression ignition engine, it is none the less an impressive technology. The real impressiveness comes in the fact that they are operating the engine in a heavy knock region that would normally destroy most engines. But they use live cylinder pressure measurement so that the PCM can monitor if things are really getting out of control. We (engine development engineers) have used cylinder pressure measurements to develop engines for a few decades now, but this will be the first application of cylinder pressure measurement in the field (in an automotive engine, anyway)
I think he describes it poorly. If it is what I think it is, then it actually has no spark plugs, but it does instead have direkt fuel injection into the combustion chamber, just like a diesel. Also, running really lean does not stop pre-ignition and knocking, but running richer does, so he has it a bit wrong more than once.
Running direkt fuel injection removes the need for stoichometric air/fuel mixture, because there is no fuel to ignite during the combustion stroke. Instead, the fuel is injected near the top of the stroke, just like a diesel engine, and ignites due to the high temperature of the compressed air.
I had to scroll down looking for this comment because I felt the exact same way and didn't want to put it up if someone else already did! That Russel Guy shed a little light on it though!
Nice video. Just now subscribed, too.
The circle cycle engine will make a spectacular bit of carnage when it goes even slightly out of sync or alignment.
The Achates reminds me of the Deltic opposed piston locomotive engine from 70's or maybe late 60's.
I remember seeing a working example of the deltic locomotive engine at a railway museum when I was TDY in England when I was in the air force! It was a way out there design, like something out of an engineer's fever dream involving the Greek alphabet! It was quite powerful and somewhat efficient but a nightmare for those who had to build and maintain it!

"Too Complicated!" LOL. Compared to what? Have you seen the inside of a Mercedes DOHC V12? And they run reliably for quite some time thank you very much.
