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.

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.

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.

It was supercharged and had the same 14/8:1 compression range. It was a small 5 cylinder and had the traditional bottom end.

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.

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.

It's amazing that after so many decades of internal combustion engines, innovating engineering creates such milestones..!!

This reminds me a little of the Stephenson linkages used in reciprocating steam engines 100 years ago.

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 😁.

Quite a radical change in design. I like it. Be great to see that technology in higher outputs.

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

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?

Very informative. Thank you for upload.

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.

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).

I don't really think that this is really gonna be a succesful engine in the next 5+ years (unless they really decomplicate it) , but the crankshaft idea is amazing and can be applied to so, so many engines and solve the traditional issue.

Great video and awesome explanation !

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.

Another great video. Thanks!!

The short story: Added complexity, more moving parts, and more to go wrong.

Seems a lot less complicated mechanically than I expected when I saw the title of the video. Always great to see innovation like this! Hopefully consumer testing reveals it is more efficient. I may have missed it but what are the min/max volumes of the engine?

Displacement remains at two liters (swept volume), with the compression ratio changing.

can u do a video on koenigsegg's new 1.6l engine?

Everyone here seems to buy a car then immediately open the engine and start working on it.Really? Please give it a break man. Infiniti engines are bulletproof and the chances you will need to open and work on it are very small to none. Appreciate the innovation and thought that went into this. Else we will still be driving steam engine cars!

Can't wait for Scottys input on this haha

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.

The Mitsubishi 4B11( and 4B11T variance used in the evo X) don't use balance shafts, you're welcome, now you know there is a 4 cylinder engine without extra moving parts that don't need balance shaft.

There are many 4cyl without a balance shaft, CA18DET, SR20DET etc. you only add one if you really want to remove the extra vibration

I believe they did that with the 4B11 because they were trying to improve it over the 4G63. Also the Honda K20A doesn't have balance shafts.

I am not sure but same engine concept was already initiated by Peugeot MCE5 engine. Thanks Engineer for the cool video.

Thanks for the report

I'll keep my 2002 honda accord with 214k ....easy to work on it.

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.

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 gear head I grew up with cast iron V 8s. 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. Bolt two onto a big block and open it up on a dyno you won’t see me for a couple of hours.

As long as high quality internals are used, technically the internal is working 50% less stressful to your conventional engine due to the crank rotation assembly only requires to do half of work yet produces the more combustion at a higher compression. Also, this new rotational design of the combustion pistons are always sitting fully square, it will be alot less stressful on the bores unlike the conventional engines that has to pushed up from an angle and putting more pressure to one side of the cylinder bore.

FINALLY some thing new thankyou its a totally new idea

Saab had a way more simple design for a vcr engine based on felf contained cylinders and pistons, saddly they were unable to develop and accurate ecu controller and mechanism for a precise and variable valve opening time management as well as a header flexible enough to manage exhaust gases in different ci oression configurations. Finally they lack the technoloy for a variable compression turbocharger.

I think a factor was funding aswell... They was forced to use GM engines on last 9-3 and 9-5 generation

Infiniti just found a perfect way to reduce engine reliability even more

That is genius. There is so much admiration towards companies like Tesla that frankly do not innovate engineering as much as traditional ICE developers.

How much is the RPM? I think it can't rev high because of that mechanism

I saw an article in the early 90's about this. 2 litre engine producing 300 horsepower and no adverse mileage over it's conventional counterpart. D.I avoids detonation and other preignition issues with high mechanical compression ratio without utilizing "Atkinson" cycle to bleed off cylinder pressure. Change every constant to a variable in the I.C engine. Variable displacement, variable compression, freevalve(infinite variable valve timing) turbocharged direct injection. Combine that with a hybrid powertrain and a renewable fuel source

After reading several comments below, I find myself thinking this. The conventional way of thinking in regards to small engines, and really anything mechanical is stuck in the dark ages. Mechanics, service centers etc shiver at the thought of something new being introduced into production. I see comments from people who maybe are complacent with their knowledge of small engines up until this new engine is produced, and that's fine, previous engines were foreign and even alien until said mechanics/techs got their feet wet, and learned how it worked. Personally the introduction of a small engine of this magnitude is a game changer, it's greener for those who want to save the Earth, it's powerful enough to easily line up with a NA V6 and hold it's own, satisfying the enthusiasts demand, and it's overall design and internal mechanics are impressive enough for those tech heads out there. Even more is the fact that Infiniti's R&D for this engine is impressive, and that's an understatement, watch the video again and listen when he speaks of road testing numbers for other production engines, many of which were industry first, VVEL... Anyone....? I'd be willing to bet the first prototypes of the VHR VQ's didn't see even this much R&D back before it's release. I own a VHR and it's a solid built engine. When it comes time to move on to another vehicle, I'm sticking with Nissan/Infiniti, they stole my heart many years ago. Thank you for pushing innovation and really demonstrating what great minds can do!

Great video 🙂 combining this with Freevalve (camless engine) would be epic.

One would think, that a system like Freevalve would be cheaper to implement than a camshaft. And still almost all engines have a camshaft. I wonder if you can retrofit an engine with such a system.

@ZylonFPV

It adds complexity in terms of the actuators and electric control unit, but overall is far more compact so less machining. I suppose a retrofit might be possible!

MrDiarukia how could it be cheaper ? A camshaft takes minutes to be machined. Whereas freevalve uses one module per valve, there's no way it's cheaper.

I was not talking about machining them, but implementing. They are smaller, easier to calibrate etc.

simply fascinating (in my best british voice)

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?

This engine seems bulletproof it's amazing what people come up with
