- The World's First Production-Ready Variable Compression Engine
INFINITI VC-Turbo Engine - Sponsored by INFINITI
Subscribe for new videos every Wednesday! - goo.gl/VZstk7
Infiniti's has developed the first variable compression ratio engine which will ever be used in a production vehicle. The compression ratio can vary from a highly boosted 8:1 ratio, to an Atkinson-cycle running 14:1 ratio. What this means is the engine can produce significant horsepower by using the low compression ratio with a turbocharger, or it can achieve excellent fuel economy by using a high compression ratio and an efficient engine cycle. Now there aren’t simply to modes the engine runs in, it can vary and run at any compression ratio between 8:1 and 14:1, allowing for optimal performance and efficiency for whatever the driving condition may be.
This video will discuss:
1. What is a compression ratio?
2. Why is it beneficial to change the compression ratio?
3. How does the engine alter the compression ratio?
4. What are the advantages of the VC-Turbo engine?
5. What are the balancing characteristics of the VC-Turbo engine?
6. How did INFINITI test this engine for durability and reliability?
The VC-Turbo engine will debut in the 2019 INFINITI QX50. It’s also incorporated within the Q Inspiration, a concept car INFINITI developed to speak to their new interior and exterior design language.

NEW VIDEO EVERY WEDNESDAY! - Auta a dopravní prostředky
The elimination of side force in combustion is like the biggest thing noone even talks about. Thanks for bringing it up; that's seriously awesome!
Can be done with any other engine design by just shifting the cylinder bank relative to the crank.
I guess so, but that sounds like it will cause a lot of imbalance and vibration that needs to be adressed.
Well, to offset the cylinder position relative to the crank center line isn't something new. For instance BMW did this with it's famous M10 engine which orignated in the early 60's.
But yes the imbalaces this creates is a problem and normally a relative complex balancing shaft is needed to counter that.
Ism Ael an easy way to decrease the side load on the piston is to install longer connecting rods. Racers have been doing that for years and years.
Or you can make the cylinders oscillate
My thoughts and prayers go out to all INFINITI technicians 🙏
Chris French Much agreed with this one
Because no customer ever misses an oil change.
As a Nissan/Infiniti tech, I thank you
Its really not THAT complicated.
They aint working on mechanical,they working on squeeks,rattles and window regulators
Engine rebuilding is very hard and tedious work.
Infiniti: hold my variable crankshaft.
Guess how many people will.
DexMaster881 enough to put out a recall
@@jjpablo Hahahahah American car recall :)
Right?! What happened to fewer moving parts and reduced friction points (on the crank/con-rod)?
The engine has perfect balance without a balancing shaft and it also low cylinder wall pressure.
It's not that complicated.
Maintenance aside, I'm glad to see that Infiniti and Nissan are still progressing forward with the gasoline engine
That mazda
Thanks Infinity, for flying my favorite nerd-gineer over to get the scoop on this. It' a fascinating design. Oh, and thanks to the nerd for yet another awesome video explaining cool engineering. :)

Simon, I like your's better. Well done, Sir. :)
PappyMan Infiniti*
Latino914, I stand corrected, sir. All I can say is "To Infiniti and beyond!". That's my toy story and I'm sticking to it. ;-) [groan]
My sincere apologies to -infinity- [damn it, I did it again!] *Infiniti.* I hope they realize that (their mizspelt treadmark not withstanding), I am very grateful for their support of Jason, my favorite "Enginerd" [thanks Simon].
PappyMan im shaking from the crriiinnggggeee
I love when companies break the mold and push for the unconventional.
I will always have more respect for the company that takes risks but occasionally fails over the one that rarely ever has issues but only uses whats already established.
Agreed! It’s wonderful to have some variety and not just another downsized turbo.
Robbie Callaghan toyota?
Robbie Callaghan Well I don't mind a company doing something new, as long as they tested it THOROUGHLY instead of bringing out something new and forcing on the public as test dummies Like what ford did with those dual clutch transmission stay put in the Ford focus,, Unlike when you compare Toyota with their first hybrid synergy drive which they got right the first time
Well, I mean, SAAB was all about that, they had a variable compression engine with very similar characteristics years ago. I don't know if it was patented and I know SAAB ran out of money before the could do anything with it.
You gotta hate Subaru then 😂😂😂
There was a diesel engine made in the 1930s called a Lister CS, which had two different compression ratios. There was an extra chamber in the head which could be opened or closed by a valve. High compression was used for starting without use of a glow plug. Once the engine was warm, the compression valve was opened to the low ratio, and then the engine could be loaded.
goodness I can't believe this took me 2 years to see. Thank you so much for these explanations! And your hard work.
VC kicked in yo!
Neo VVL
Oliver Lowe I can see this joke being used in the future😂
JulianBlyat I think your right on that.
Loooool
- A ricer, 2045
SAAB had a variable compression engine concept a couple decades back. The entire head would pivot a few mm on it's longitudinal axis via an electronic actuator (motor), like a hinge. It was supercharged and had the same 14/8:1 compression range. It was a small 5 cylinder and had the traditional bottom end.
It had a rubber skirt needed to seal the crankcase and allow movement of the cylinders relative to the crankshaft.
@@louisallen1437 That rubber skirt would have been a nightmare to replace, if it was single piece.
I will wait for the engine with RGB lighting and glass hood to show my homies all the diamonds and platinum I have on the radiator hose
Yes, but will the CVT transmission fail before the engine?
why not both
Probably
Lol it becomes the worlds most reliable engine on earth because the rest of the drivetrain fails before the engine has a chance to
Now it's a race to see what fails first.
Did they actually put it with a cvt?
Love the animation
Thanks Infiniti and EE :)
Very welcome, thanks for watching!

+Engineering Explained I luv cars and I trust your opinion so I would like to know what engines would suit being turbod AND supercharged that weren't done already and also want redline would you say if fall proof and what capacity and how many cylinders it has also what redline would you say if you you mixed tuner exotic and muscle car (the common types) and created a engine based of three to try get the good parts of them all I think that you will enjoy doing a video on that thank....PS what engine is better this one or the Mazda holy grail engine? plz be honest and not paid ;):):):)
Great video and wonderful stab at trying to explain this new complicated motor in about 8½ minutes.
His name contains Explained, thats his job :D
Looks like a handful at first, but if you know how leverage and fulcrum points work it's actually beautifully simplistic. The controls to make it all function optimally on the other hand.... well I'm sure it took the electrical engineers and programmers a good bit and a lot of coffee to get working somewhat reliably for testing
Great video on VC engine. Fifteen years ago, I designed a VC V8 engine that used a different mechanism. I altered the capacity in the combustion chamber and left the crank alone. From that, I designed a new engine; flat 12, (2) inline 6, 2 cranks, shared head with VC mechanism, forced induction. From that, I was able to go from 4 stroke, to 2 stroke with full time forced induction. It worked on paper, would love to see if it would in real life.
i'm glad they respected you enough to represent them,good job
WOW!
That is outstanding that Infinity hooked you up like that..... and it really shows that your channel is watched by smart people that wish to thoroughly understand the engineering of an engine! lol
Sadly though... I drive a 12 STi.... with an engine design nearly 30 years old... Sure it's been updated of course, but at it's core... it's OLD.
+TheDBall73 30 years old? What about it is 30 years old? Do you just mean the EJ platform or whatever?
Older designed engines are the most reliable
bokkey45 While normally I would agree I think lack of innovation is what kills companies. Take the 22RE from Toyota for example. The engine was a hell of a workhorse and reliable. But they dropped it. They had to innovate. Get more power and mpg out of an engine. That’s what these car companies have to do now. Or else electric will completely leave them in the dust.
EJ25 went into production in 1988.... Like I said it's been updated with fuel injectors instead of a carb and several other things, but it's still a 30 year old engine block, heads, and intake.
TheDBall73 And what's the issue? Old engines are the better, boy! More exciting
Amazing video, packed with information. You consider our time valuable and you make the most of it. Thank you for that! Amazing engine as well. Kudos to Infiniti and I look forward to seeing the results in the market and plenty of sales.
I appreciate the kind comment, and absolutely agree! Try my best to keep it information packed, while not repeating information much or straying from the subject.
Once again, another phenomenal explanation! My auto school used this video to test us on the Variable Compression engine, needless to say, just scored 100% on the test! Thank you for always explaining complicated things in an easy to understand manner!
Engineering Explained: Excellent job on presentation and video narration. You covered all the important points.
Thanks!
I'm happy for you and the success with your channel. Thank you very much for sharing your expertise and taking time to put this together.
Very welcome, thanks for watching!!
Fascinating engineering and design, very interesting and well done video.
Thanks!!
agree on all points
Charles Butler I remember seeing this years ago as a French prototype engine and had very little to do with the infinity brand at the same time as the Saab engine prototype
+Engineering Explained Next time make a presentation or review of a "Radical Engine Design" from Achates Power , they make OP (Opposed Piston) Engine combined with Compression Ignition for Light Trucks ;) !!!
This is actually very clumsy engineering. I'm an engineer and junior designer for Hyundai, and I can confirm now that this is the most uneconomical, unpractical, and expensive VC engine I've ever seen (aside from Renaud's engine). VC engines can be fantastic -- it's the future, not Teslas, but this simply isn't the way you go about VC.
I love my 2019 qx50!!! Once you learn how the CVT response works(which was a learning curve)you will realize going WOT isn’t really needed if your in a hurry.
- how many moving parts do you want?
- yes
I love that I work as an engineer for this company, and yet I’m learning about the product through you lol the main thing I wanted to know is if it’s truly a variable compression or if it was lock to lock. You answered it. Thank you!
Loved this as all your stuff. It is now technology instead of magic.
Also I feel in this case complexity actually improves longevity by mitigating the engines stress points and imbalances.
My Dad and I were always planning on making an offset crank engine to reduce side loading. I'm glad to see the idea has finally made its way into the production world.
Very informative. Thank you for upload.
Thanks EE! As always, a wonderful explanation!
Thanks!!
Engineering Explained hey.. Can you please do a video on 2 stroke diesel engines
Oil changes just got that much more important, especially in a Nissan
So here and the problem of the side forces from the piston on the cylinder walls resolved... Bravo!
Just about the coolest thing I've seen in a while!
Balance shafts add complexity? This engine is the definition of complexity. Will be interesting to see how this stands the test of public use.
Wonder how long this design will survive when Jane the Soccer Mom forgets to change her oil :)
Exactly my thoughts, instead of 4 main bearings to change you have, erm, lots! It won't be economically viable to repair. Not only that, but aren't they flogging a dead horse?
It's still too early to presume that ICEs would be completely replaced because BEV's aren't all that green technically. They rely upon Non-Conventional energy sources to produce power and ultimately pile up a lot of in-disposable hazardous waste. Also, battery pack replacements are gonna cost you a fortune!! So, all the marketing gimmicks aside, ICE still has a future until the all the issues get sorted out.
all that considered, they are still "greener" believe it or not. They are not the magic cars that savve humanity like some play it off. but they are still an improvement today over what we have been using up to this point.
A lot of the issues you mentioned are becoming less of an isue as well, For example, A huge portion of the waste comes from the Lit-ion bat production and disposal. but there are already systems that have reduced waste and found means of re-use from most of the "waste". The goal is 100% renewal. i think thats still a bit of a pipe dream, but they are defiantly well on the way,
all that aside though. its going to take a lot more than just being "better" economical or environmental options for them to truly dominate. some people just like combustion motors. they like the sound, the feel, they like the complexity, tinkering..... these are things you cant just replicate, and thus will continue to push a market long past its "prime"
I don't disagree with the fact that the most efficient ICE is still not able to convert much more than 50% of the available energy into useful work and that too with the help of MGUs. I just disagree with the common notion that this is the END of combustion engines.
Rocker arm on the crank to adjust CR, its simple, but Amazing ! Hats off to Nissan , and Another Exceptional presentation, Thanks!! EE !
It's funny..the negatives comments about being hard to work on or that it will explode get hundreds of thumbs ups, but comments like yours get few. I totally agree, hats off to Nissan! I hope these engines work awesome and deliver what they're looking for and more. All those negative guys probably said the same things when fuel injection then when turbo's were introduced! "ohhh...those turbo chargers will never last, they'll blow up, they'll be a nightmare blah blah blah"
How do you guys think innovation and advancement occur? By developing new things!
An impressive engine concept and well done video.
It's amazing that after so many decades of internal combustion engines, innovating engineering creates such milestones..!!
VC just kicked in yo
Quite a radical change in design. I like it. Be great to see that technology in higher outputs.
Nice video as always. Cool stuff. Thanks
Before being applied to internal combustion, this variable compression/displacement setup was heavily researched and developed for fluid pumps. AMAZING design, but I do worry about its resilience to inconsistent maintenance as the years go by.
Scotty Kilmer channel in 2021; Why not to buy an...
that's what I was thinking during watching this video lol.
Bingo Bingo I can't wait to see what all Scotty's got to say about that motor
He is probably right like he usually is unfortunately :( new cars suck
ICE powered vehicle
Besides, no secondary balancing needed, both injection types (port and direct), internal exhaust (more longevity for turbos), less cylinder wall damage...this is seriously not a bad engine design that will unfortunately be obsolete by the time it's affordable.
Great video! simple explanation! thank you 👍
Brilliant idea, control comes to a certain cost and if that reduces vibration and you get a more balanced motor, this is truly the best gain.
Another great video. Thanks!!
Nice video and information mate. Good stuff!
Thanks!
so in very basic terms, it has adjustable crank throw
bikerdhill ok make something better then
No not different crank throw that would increase and reduce the stroke think of this as a system that raises and lowers the whole crankshaft.
@@spedracer55 dont make anything,,,,,stick with what worked 20 yrs ago and still does and is affordable,,,,im at 292k miles on my ford and its never needed repairs,,,,not as much show or power but reliable and affordable,,,,,if you guys just have to have all sorts of complexity and computers then have at it,,,,as for me,,,,i can fix mine but have never needed to ,,,,dont have wild hp but manage to get along quite well without it
@@bill45colt if everyone though like that you wouldnt have your car, the technologies that go into it were once also considered experimental and unreliable.
@@lithobreak3812 True.
Here because I saw this on your FB page, and wanted to see the full video. What ever became of this? Anything? Just curious. It does seem overly complex, but I'm glad engineers are constantly trying to figure out new ways of doing things.
I like how infiniti/nissan is taking steps into improving their engineering. It's something new. Thank you for taking the time making this video. It's nice to see new vehicles that aren't electric powered. I'm very interested in how this new engine holds up with it's competition. Also, I'm interested in how they can further improve it in future infiniti vehicles.
Great video and awesome explanation !
When i first heard "Variable Compression", my immediate reaction was "What have they done with the heads?". And to my surprise, the answer was - nothing.
Nebojša Stojilković ..Yeah same here
Yeah
I just purchased a 2022 Rouge. 1.5 liter I-3 VC Turbo. Wow! great performance and 35 MPG!
Just got a Qashqai e-Power. (afaik it's the same or similar model in EU). I love it too, but I'm really keen on getting some insight whether these engines proven to be reliable. I hope so.
FINALLY some thing new thankyou its a totally new idea
I might only be a kid, but your content is AWESOME i'm glad my teacher told me about you :3
Thanks for watching, and tell your teacher I said thanks for the recommendation!
Will Do
Well what can i say it's a master piece of tech going to next level!!
Also nice and very detailing video E.E good job ;-)
Keep it up with more new tech ;-)
Thanks!
Twice as much to go wrong and three times the repair cost!
What do you tink about the Duke engine?
Great explanation- thank you!
Direct and port injection. Wowwe. Also like that integrated manifold. Interesting stuff from Infiniti.
Ok now, lets just imagine something:
Mazda HCCI + Infiniti VCT + Volvo precompressed supercharged-turbocharged system. Take the best of each and make it into a single engine. Now this would be something.
Than make it a V12 sheeeeet.....
David Miletič Congratulations, you just imagined a $50,000 engine.
Jordan Hillard Worth every dollar.
As a mechanic, this is going to suck to repair in a few years.
They could end up throw away cars which would pretty much off negate any carbon emissions saved by the increased fuel efficiency.
Armando Latour Haha so true. If just one of those extra pivot arms/rockers fails, bye bye engine!
I was just thinking that. haha
legionary illuminati really? Doubtful considering myself, and everyone I know, literally know 0 people that own an electric vehicle.
electric is too far behind sure we cam get cars to go 300 miles on a charge but after what a 4 to 8 hour charge gas,diesel,e85 etc you can fill in just 2 to 5 min until electric cars can charge in a matter of minutes or until under half hour but then you have the waste of the batteries after they are worn out which if they leak or blow up are more harmful to the world then emissions
as always a super presentation well informed easy to follow .
AMAZING bit of engineering!!!☺️👏👍.
Until you need to sell your house because it costs more to fix than the conventional enginr
That's impressive. But that's a WHOLE LOTTA new moving parts. I'm curious to see some consumer reports after the first couple of years of production. I'm also curious if there's going to be a big hesitation while the computer is thinking about which CR and fuel delivery it wants. Pretty cool and very innovative. I remain skeptical though 😁.
Amazing!,I wonder when this tech will be coming to Lawn mower engines,Fuel Racing etc.Maybe take 20 years but concept is very cool.Thank you EE for a fine video and such a great job at explaining.TY73s
Lol, its going into the QX50
push mowers don't even have fuel injection yet so keep dreaming
20 years haha cmon now, this engine will be ancient 20 years from now...
By then, all smaller applications will be battery powered and this engine will be outdated. This is, unfortunately, just a small postponement of the unavoidable paradigm shift in vehicle propulsion.
Sadly I agree with you. This seems to be a triumph of ingenious engineering, but 10-20 years too late. The days of the IC engine, however clever, are numbered. The major downside of this engine is the added number of moving / reciprocating parts to go wrong. Hundreds compared to the dozen or so, rotational only, in an electric car.
How does this engine compare to its rivals / immediate predecessor in actual numbers (HP, fuel consumption, torque, emissions etc.)? Does it have a flatter torque curve and hence, possibly, require fewer gear ratios?
I ended up watching this because I was confused by the thumbnail on your video about compression ratio. This is a really neat idea.
This reminds me a little of the Stephenson linkages used in reciprocating steam engines 100 years ago.
These will rarely if never be overhauled. When worn, the vehicles will be totaled, just as many other modern cars. I was at the metal recyclers a few weeks ago watching truckload after truckload of late model cars being brought in for shredding with no apparent external damage. No a dismantle yard... a metals yard where cars are immediately shredded for raw materials.
+Jennifer WhiteWolf : I agree with your premise. Only time will tell what will come of this engine and how it will hold up in the "real world". It's still pretty cool and will be interesting to see how well it holds up.
Turbo Diesel
It certainly is technically interesting... I will grant the design its due respect in that regard. It does solve some difficult problems with levers, cams, and well understood cylindrical bearings.
All re-usable parts should be re used as 2nd hand spares.
Environmentally Friendly is to use an item until it wears out or breaks. then recycle what's left.
New cars that get Totaled , all the undamaged parts should be re used and the damaged parts Destroyed.
If you dent a panel on a 2 yr old car, What is wrong with a replacement 2 yr old panel ? it matches the age of the car.
And is no better & no worse than what you had.
( Obviously scrap all the safety items that were damaged in the crash. )
Body panels, Interior trim, Glass, and many other parts are Perfectly Good & usable..
yeah more stuff to fail. Will see
Car manufacturers don't make money off cars that are already sold.
Saab was also experimentig with variable compression ratio
Ruben b yes but they do it by changing the head gap
I think SAABs design was much more elegant. To drop the SVC, the name of the engine, was one of GM:s many bad decisions that finally killed SAAB.
I disagree. I think rocking the whole cylinder head is far more crude. Doesn’t that not only change the size of the cylinder, but also the geometry? Many engines have carefully shaped chambers and pistons to maximize combustion events. Rocking the head affects that, no?
Kenny Howard what Saab did was integrate the cilinders in to the head and move both up or down with respect to the crankshaft. So the head with respect to the cilinders remained constant. Their main problem was oil seals. Have look at their concept.
@Ruben b: On the outside, the head rocks and noticably changes angle. Was there some internal mechanism to maintain cylinder geometry? Seems that would be complex.
Only time will tell the overall reliability of this design. I give them credit for thinking outside of the box. I do find unique engine designs quite interesting. One of my favorite engines ever built was by Honda for the nr750
So! Many! Bearings!
new owners in a couple years:
"Well if I woulda known it was going to be such a pain and cost me so much money I never would have..."
I'm curious how many pieces this block is? With two cranks, basically, and all the connecting rods it's gonna be a hell of a thing to torque all the bolts securing everything together.
What infinity did was amazing i once thought that if somehow the piston rod length also slightly increase the cylinder housing(like Older Radio antenna) can be changed which will help in create more power. i used to drive a 110 CC scooter and thing came to mind that how can be possible to let 110 cc engine behave like 125 cc engine. so by extending such and changing compression something can be achieved. This was somewhat exactly the thing.
The short story: Added complexity, more moving parts, and more to go wrong.
Yup
*Rotary_Engine has entered the chat*
I'm a mechanic for 40 years now, this looks like they've thought of everything but my concern is lubrication. I'm not sure that the offset links will get enough, good idea on the piston side load but there seems to be a transfer of it into the offset links, (a greater rotational speed at fulcrum points could spin a bearing in a start up scenario).
What about additional friction loss? Was there any info on it? Also can we talk about how amazing the engine model is? I wonder who makes these models.
This engine seems bulletproof it's amazing what people come up with
I have a particular concern with the harmonic drive; when it fails, will the engine fall back to a setting that favors efficiency or power? It's nice that it is a mechanical linkage and it's all really pretty. Will it be a transverse only layout or will there be plans for a longitudinal variant?
simply fascinating (in my best british voice)
Man you're up early this morning.
So are you
This dude is amazing and deserves every subscriber he has and more
Thanks for the report
Can't wait for Scottys input on this haha
He talked about it.
How much is the RPM? I think it can't rev high because of that mechanism
I’m old school at 58yrs old. I’m glad to see new ideas . It looks impressive like they thought of every efficient thing possible. It’s a little confusing to me , but if it holds up and saves fuel then more power to them . Thanks for sharing .
Awesome. Innovation for sure.
Rotary engines was great due to few moving parts & died due to poor emissions
This engine has 10x more moving parts to fail but that's okay it gets 36 mpg on premium fuel.
How many bearings are there ?
2 on each fulcrum (8) the lever end (4) and crankshaft arm connection (4) and the crankshaft main bearings (4) and maybe more ??
Simple is best for short & longterm gains.
A wise man once said, " Just because we can doesn't mean we shouldn't stop and think if we should".
Hmmm🤔🤔🤔🤔
Opposed piston and Duke engines are much more realistic for practical application without complexity getting in the way of profitability.🤑
I wonder how much money they put into developing that clear demonstration model
Peanuts i guess hehe...
Erkk so sad...
Not nearly as much as cutting, testing, measuring, recording and analyzing prototype engines.
This engine is simply a work of art.
Best engine review in century~
Don't expect to repair the motor from non dealer mechanic after warranty is over.
Why not? It's all just nuts and bolts.....
Toe Toeknee wrong, it’s easy to be fixed
Why not? Many shops take on major work on late model vehicles fresh out of warranty.
Dealership information is usually a resource many reputable shops have.
Of course they do not always disclose everything
Toe Toeknee you have definitely overestimated the competency of dealership mechanics and underestimated all the good and smart mechanics everywhere else. Well, I am not surprised at all. You are inherently a Chinese descent.
Japanese and Europeans seem bent on perfecting the combustion engine to derive maximum power and efficiency. I wonder though if they will be able to compete with much simpler electric motors with the passage of time. Remember all the hoopla about turbo engines. I don't think they turned out quite as promising as they were cited to be.
I feel bad for the people who buy the first production year of this model
I don’t. They probably have more money than either of us.
Z
Unlike GM Ford and Chrysler. The Japanese car manufacturers have embraced technology and believe in first getting it right instead of being first to get it to market.
Just look mitigating diesel emissions. They started back in the 1980s and have had reliable DPF and and SCA since the early mid 1990s. The Japanese embrace the concept of technology and conservation.
Here the ignorant and inbred masses insist on staying with outdated technology. That is why The Japanese will always be at the top of the technological food chain and us intelligent Americans will be trapped on Walton Mountain with the inbreds.
@@bdb3350 I like vehicles that can be fixed in the garage by 1 person
Josh Girolamo
Are you talking about being able to repair your own vehicle at home? There I agree with you 1 million percent.
As a Gen-Xer

I still get sexually aroused from the sound of a 262 -400 CI with a Rochester Quadrajet. At wide open throttle.
Especially when those secondary plates stand on their ends, and they are inhaling 800 cubic feet per minute.

Best explainded !!!
Excellent ideas realized here! 👍🏻This is real progress. Thousands of Indy race car engines have been wasted due to detonation. Here's the answer, With extra benefits! Beautiful!! 💜
can u do a video on koenigsegg's new 1.6l engine?
This is great an all... Until the compression gets stuck at 14:1, it hits boost, and the cylinders are vaporized
witch could happen if they thing that switches modes is a damn electric engine.
Vital Mendoza I would imagine it fails into the safe position of 8:1 so you will just end up with a slugish response off boost.
Well "vaporize" is a bit harsh. I'd say "melt".
Similar reault to what happened on the 6.0l fords VG turbo. Vanes got stuck in the fast spool position which at higher rpm caused too much boost and blown head gaskets lol
@@danielh4995 lol
Thanks for explaining. Nice to hear about new tech for ICE.
Don't get me wrong, I love zero?maintenance of EV's -not considering the battery-.
Brilliant engineering.
