Nissan VC-Turbo engine optimizes power and efficiency
Вставка
- Опубліковано 13 жов 2024
- Nissan's VC-Turbo engine offers any compression ratio between 8:1 (for high performance) and 14:1 (for high efficiency). The engine delivers 248 horsepower @ 5,600 rpm and 273 lb-ft of torque @ 4,000 rpm (premium fuel). The VC-Turbo's specific power output is higher than many competing turbocharged gasoline engines and comes close to the performance of some V6 gasoline engines. The unit's single-scroll turbo ensures immediate accelerator responses on demand.
Along with the world's first multi-link system, the engine features an electric motor with a unique Harmonic Drive reduction gear to manage the variable compression ratio. The electric motor is connected to the Harmonic Drive with a control arm. As the Harmonic Drive rotates, the control shaft at the base of the engine rotates, moving the multi-link system within the engine.

This motor has now made it even more crucial to change your oil religiously. So i just watched a video where this motor was torn down. Its honestly a amazing motor, a lot more to go wrong but that's the sacrifice. Its a pain to do any engine work if it really came to it. The tear down video showed everything in the engine to be extremely healthy and clean even after a failure. The failure of this engine, so far is only the bearings and piston side skirt coatings. With time and a little bit more R&D on bearing materials and side skirt coating this engine will be very promising and reliable. During the tear down the bearing spun and the material was all caught by the oil filer which was fantastic, keeping the whole engine very clean and healthy. Honestly if the bearings and side skirt coating get addressed which i wouldnt see it being very hard since its only two issues and lets be honest its probably a money thing, this engine will be a very successful and reliable motor. Nissan please put the extra effort into the next revision of this engine and address these two issues.
i do car video ?
This is actually a revolutionary design because even though there are added parts from the Compression ratio Actuator thing, You can see that the design made the engine run smooth enough by itself, that it doesn't need any balancer anymore. Plus, the crankshaft is offset, which allows the combustion stroke to be much more linear, where not only the Efficiency is upped, but also gives less stress on the piston and the crank. So, the lifetime could be possibly lengthened if the design is improved even further?
Well, there are 2 set of rods and a complicated balancer. It's complicate even sparing balancing shafts
"Hector is gonna be running three civics with vct engines"
Johnny Figueroa this would have more thumbs if people had good taste.
😂😂👌
Real talk 😂😂
He wouldn’t take out the VTECCCC
He has a whole stimulus check in vct upgrades you can't bet your pink slip jessy.
1:22 This is so awesome
Fix It Angel ，讚！
Very engineering
Engineer have been struggling for decades to find a perfect solution for compression problem of high speed engines , here there have done it eventually .. awesome 💪🚗🚗
Love it!
Variable Compression Ratio + Variable Valve Timing + Active Cylinder Management whould be epic
A lot of technology in one engine.
That won’t be reliable.
@@pattycarljackson why?
Luminous65 having Variable compression in one engine is going to put a lot of stress on that engine not to mention it’s a turbo and they do fail before the engine will fail and they can destroy the engine. On top of that it’s Nissan they aren’t the most reliable care company.
@@pattycarljackson ok but you can adjust boost to make engine really close to N/A on high CR or increase boost for low cr and high compression ratio is not always bad, Mazda make engine with compression ratio about 14:1 and this make their job right
And it is True about nissan
Luminous65 it’s Nissan I’d never trust any of their CVT’s, Automatics, or this new engine. Let’s wait a couple of years and see how well these engines actually hold up. People think because it’s new means it’s reliable and that is absolutely not the case.
This is VC turbo, powerful engineering the better porformens is better the future, advice speed and technology. Nissan innovation that excites, distributed by courtesy garage.
This is an amazing engine design that variable compression rate is not achieve solely by valve timing but actually varying the stroke. the no lateral force on down stroke is also achieved with the design. It's an expensive engine to make with more mechanical components.
I just leased one of these and the change over is seamless. The Xtronic CVT in the 2020 Altima is years ahead of any other CVT I have owned.
how is it going? I hope it's reliable and no issues. Very interesting concept.
CVTs are not as strong as their geared cousins
yay more moving parts! this is going to last forever!
What you are saying is the equivalent of being afraid that a crankshaft or connecting rod will break. It's like being afraid that one of the 2 crankshafts of an opposite piston engine will break. So why not take a 3-cylinder engine, the real problem with having more moving parts is that they do not hold, in fact, this engine will prevent the cylinders from turning into ovals and the connecting rods at the time of exploration will be exposed to less stress. in terms of the new parts because it's like being afraid of breaking a crankshaft
Yes, more points for failure. A turbo, direct injection non self-cleaning engine with a movable crankshaft spells trouble.
Nothing lasts forever idiot. Compression ratio is improved on a stock vehicle and you’re mad? HA!
Yes. Because this car is not for you who cannot afford it
@@riosena350 hey now that we're 3 years down the road and these are exploding left and right, how are you doing?
Its a really good thing this engine produces it's peak at such a low rpm. You can see that this engine can run on a low fuel economy.
Nissan has done it again folks the new generation of turbo and engines
VC-Turbo engine + CVT?!
What is that, 50 mpg city, 100 mpg highway?!
Sounds great!
Unfortunately, I still want my V8 after this 2015 altima 3.5SL finally dies on me... whenever that is considering it's clockwork maintenance and overkill with the fluid flushes for me!
392 V8 are going away next year, but not only do I like no car payments, i'm 100% sure I can get this altima of mine to 200,000 miles!
Ah what to do!
But Shinichi Kiga, Nissan's chief powertrain engineer, told me the VC-Turbo engine creates less friction than a regular engine. The secret: Nissan engineers moved the crankshaft out from being directly underneath the pistons' bores and offset it about 15 degrees. That, in combination with the multilink assembly, eliminates the usual side forces that act on a piston as it travels in the cylinder. In other words, the piston is pushed and pulled straight and up down in each cylinder.
Did you mean: Shinichi Koga
I've seen a tractor engine from the maybe 60s designed to run on any available fuel, so it had a large screw in the head. Turn it in, it increases compression. And that was it.
Impressive ! Nissans computer graphics animation skills is unbelievably AWESOME.
VC-Turbo kicked in yo?

Lol new meme?
Lol
Lol
Yeah, fuck yeah
Vc-turbo paaaaaaaaaaaaa 🤣
This in an RB26 😍 mixed with Skyactive X principes plus Camtronic from Mercedes and we have a high power super eficient engine with an awesome Sound
What ground breaking technology. In theory and hopefully in practicality.
Looks cool, hopefully it holds up for a long time but I'm sure they would have tested a few for longitivty of the engine.
More moving part- more room for failure
@@anpham8107 yeah, it's always factor
When these start crapping out I'll be waiting for the VQ to make a comeback 😎😎😎
UGLY-DUCKLING-ROASTS
VR>VQ
yes sir. 100% agree. the VQ is really hands down one of Nissans greatest acheivements. the power, reliability and ease of maintenance has been totally underrated over its lifetime.
@@AlienPizza38 without the VQ there would be no VR or VHR .... the VQ series is Grand Daddy Eastwood himself, for all of nissan's modern V6's
Nissan is the largest, most successful and reliable car in the world. I am a lover of Nissan Qashqai, and I hope that she will have it in the future
As a fan of ev, I cannot argue that gas engines are a marble of engineering and an important step in human history
mom lets me drive this (2019 altima vcturbo 2.0L) to go pick up food and boy that little engine and that turbo kicks in . its pretty good
This seems very interesting but I feel its the Cadillac v8-6/4 of its time. Not going to take off very well, overly complicated for our time but will spawn many ideas for future engines
Trazendo essa tecnologia para os carros flex até mesmo aspirado seria um sucesso, uma maior taxa de compressão para o etanol, uma menor para gasolina, até mesmo uma alta taxa para o gnv... Muito promissora essa tecnologia.
Very nice presentation of the concept. Thanks nissan.
I guess the all new 2019 Nissan Altima use the Variabel Compression Ratio Turbo engine, in short, VC Turbo engine
I wonder which one would self destruct first the engine or transmission
Painful accuracy
Clayson Webster if dimensioned right no one, but thats not the aim of todays car manufacturers.
It's sad to say the balance shafts are there for high rpm balance as well and Nissan went and f'd it up trying to be efficient on a turbo engine....trying to physically move the crank upward when off throttle leaning out the motor...how would this take affect in a cvt trans vehicle whilst moving 15mph and then proceeding to punch it then let off after reaching top of the rpm band while in sport leaving it in "1st"...
Clayson Webster not possible the don’t design engines to explode that way..... you think they will just explode when something like that is new and they only build it to explode.... no they don’t......
Too much parts to fail prefer mazda skyactive
wow, kudos to the engineers and the executives since the IC engines days are numbered.
Nope.electric cars don't have future.
Your demonstration is compatible with old trains drive system. Indeed , it’s old, but, extremely, correct. ✅
OMG Nissan is Awesome 🔥🔥
I wish that JDM cars should get the fame once again. 😍😍😍
Nissan knows what they are doing if they can build the Skyline GTR series they certainly know how to build a new motor with new technology
Being a newish concept brought to the market by Nissan, this will inevitably explode spectacularly at depressingly frequent intervals, be picked up by no other manufacturer, and quietly get dropped in a few years time. Enjoy!
R Soul Pretty much lol. The Japanese always did this kinda thing and when they do get it right, they get it right pretty well.
Calculator yeah, successful stuff like Honda 4 wheel steering, Yamaha 5 valves per cylinder, or anything made by Daihatsu. Apologies to all you Daihatsu fans btw.
They copied infinity's idea....
Olivier Haman yes, I am sure the corporate lawyers at the stand alone and totally independent manufacturer ‘infinity’ will be immersed in volumes of litigation regarding infringement of their steadfastly original and copyrighted design, that in no way is the work of a parent company. Noob.
R Soul You have no chill lmao
Proud Nissan owner. From Sr to rb love em all
even the leaf...or the micra...or the cube?
Shed MX my favorite Nissan sedan is the b13 add an sr20ve to that mix. Legend
dosnt really answer my question
Shed MX I love Nissan more than others, I love the culture, the history, the glory of motorsport with nismo, with such a great car and great machines. but, it doesnt say that I love that car which you said earlier, like honda they have terrible creation also, toyota has, mitsu has, every single damn car company has. so shut your mouth and sit down ! you dont really have to criticize other people interest so on their love in car or engines. so is my reply above answered your question ?
Hukukul Ibat just becuse i ask if he liked the bad creations, it does not mean that im critcizing his intrest. So dont jump to conclusions. And dont be rude
Variable valve from honda + Variable Comopretion from nissan = VVVTECC
The best tech in the entire world 😂😂
lol
dont forget mazdas tech as well
skytech vvvtecc kicked in yo
Right.
All that new development just for 26 mpg.
Combustion Engine tech has reached its peak. Any new improvement will be very small but will require huge amount of resources to achieve.
Battery Storage technology is the growing field and is the future.
It seems as though the variable compression is used in this case to increase reliabilityin high boost mode. This is great on paper but in practice it leads to a very narrow power band and low efficiency: cite: brm h16/v16. I would think the variable compression would be better set to low for startup and not much else in this case. I would like to see more data on how it is used in high power modes of operation, and that it does indeed actively change compression under high demand to limit the narrow power band found in low compression high boost engines. Until then i will still have little confidence in this and similar technologies.
Thanks
First SR Neo VVL destroyed VTEC
Now this
CANT WAIT
日産の開発力と横浜工場の製造技術力。本質的な技術革新で面白い車を世の中へ。
Like other GDI engines, direct injection while in high compression mode would screw up backs of the valves as happen in GDI engines (such as those of KIA).
In this IT age, I thought there was no room for innovation through mechanisms. This engine encourages me.
IT still needs to manipulate this design
Удивительно! Это действительно очень толковая концепция! Великолепно! Пара минусов - бо́льшая материалоёмкость - это бо́льшая масса двигателя. И бо́льшее количество элементов - снижение надёжности. Но с современными материалами это не проблема. Также понравилось, что кинематика такого кривошипно-шатунного механизма эффективнее (проход "верхней мёртвой точки"), чем классического. Молодцы!
Wouldn't be a Atkinson/ Miller Cycle with turbo-support be much easier than this highly complex masterpiece of engineering? Greetings
Definitely. This thing will be a big problem for Nissan, it's too complicated.
Stunning imagery
Mechanics are going to make a FORTUNE off this nightmare!
Now imagine this with Mazda sky active tech🧐
And add camless valves to boot.
Mazda has a fexed compression ratio, in the case of Nissan, the compression ratio is variable!
imagine the name of that shit
this technology is for turbocharged engines. mazda's skyactiv engines are naturally aspirated and they does not require variable compression.
@ffhgu 07Nissan's Variable compression engine is a wonderful design it will adjust to good or poor fuel quality by automatically adjusting the fuel ratio now try that in some other engines which comes with a specific grade fuel rating.
Nissan can you make a V6 Variable Compression Turbo For the Pathfinder and that thing will fly
VC Turbocharger will fit into any Nissan future models such as Nissan Z, Nissan Patrol and the Nissan Skyline R36.
Nissan siempre dejando a la competencia como basura 😍💙
Asi. Hermano como hermosa basura. Pero QX50 es muy caliente!
Meanwhile, here in America, as we continue to redesign LS and Hemi.
My 1st Japanese Car was a 1976 Datsun B-210 Hatchback 4-speed
Im a longtime Nissan owner. presently a 2016 Maxima and a F150 (not Nissan).
The new altima brings the variable compression engine to the masses. I'm Concerned about long term reliability.
what we need its a video about Nissan Skyline R34 Z-Tune, and history of Skyline
i think the more moving parts inertia less lifetime , more complicated
but the advantage is more controllable for better dynamic performance
Круто! Приятно знать что мы куда то всё таки двигаемся в вопросах двигателестроения. С другой стороны, увеличение массы, поднятие центра тяжести и влияние на конечную стоимость, думаю не позволят реализовать эту технологию в таком виде.
welcome on EURO6 for gasoline engine :'( manufacturers need to use these things to get rid of the GPF particulate filter
Nissan is getting so close to there huge comeback
I guess I don’t understand, the first thing I noticed is that for a stroke of the piston you are moving the output shaft 90° where in a conventional engine for a single stroke of the piston removing the output or the crankshaft 180°. Somehow the extra energy that is gained by variable compression ratio Hass to make up for this and more
It is an ART.
Just dream, no more for production, whereas in the world no need talk just action
Why is NHITSA looking into having Nissan recall the VC turbo engines? My 2022 (only 10K miles) runs just fine, lots of power. I sure don't want my engine replaced via a recall, it'll never be the same.
The federal entity is opening an investigation involving over 450,000 Nissan Rogue, Nissan Altima, and Infiniti QX50 models, which use those two engines. According to the NHTSA, owners are reporting knocking sounds, loss of power, metal bits in their oil pans, and even total failures. Nissan has made changes to the engines' main bearings and L-links since they've been on sale to address potential engine damage; however, a recall hasn't been issued yet.
I can't see the added complexity holding up long term, a chevy small block from 40 years ago should be the benchmark in longevity. Hella nice brown shoes in this vid tho.
I don' wanna seem pessimistic,but this needs wayyy more investment on it,basically on oil cerculation,cause with two connecting rods(and one not able to hit revs during the cycle),it can't move oil on the basic connecting rods.I think that can be solved with more oil within the oil panel (around 4-6 litres) or maybe a dry sump oil system,either way the cost is gonna be high with aaaall those things in it.I'm glad that this variable compression ratio system is aaaalmost fully mechanical,so reliability will be an issue only for the fact of the material of the bottom connecting rods,cause they take almost twice as much pressure that the other ones
Nissan and Ford, both going down the crapper, and FAST.
Most people on here are ignorant. These motors are really well designed and reliable with good solid tech behind it. Even though infiniti really used the most potential out of this motor it’s a good solid option for people who want a nice car with reliability. If your car isn’t reliable it’s probably because it’s clapped and never well maintenanced
Can't wait for Serena Turbo
Nissan the best petrol engines !
Yo for realz, aside from paying premium for OEM parts, this engine has some insane tuning capabilities. I can't wait till people realize that.
Ok Nissan, make a 250hp 2500lb/1150kg *REAR* wheel drive car with a *finite* gear transmission for 25k. :/
Nissan, is this different from the supercharged super high compression motor you are working on?
Que loucura o moto aumenta e diminuir seu curso e pressão. Deve ser muito bom nunca tinha visto algo assim
Я впечатлён великолепное решение. Вот только смущает непосредственный впрыск. Несколько порций топлива в такте сжатия видимо для улучшения гомогенности смеси тоже интересное решение. Да и снижать степень сжатия очень помогло бы турбодизелям на мощностных режимах снизить конечную температуру в камере сгорания и следовательно выбросы оксидов азота о которых все парятся, но это уже лишь предположение.
As a mechanic I love the video, very impressive, but spending all that time in developing a combustion engine is wasted. The electric motor is still much better.
theory816 nope, ev’s don’t have a good engine note
Electric cars are a novelty. Won't ever be a real thing.
Can’t agree with this but good take. Not to mention most EVs don’t even have the range of a modern four cylinder still which is honestly sad.
Electric is a fad, plus there will never be the electric infrastructure to support everyone charging their cars and large haul trucks. California barely has the infrastructure to run everyone’s AC with out brown outs, how do you charge cars at the same time. My outlander get 42 miles per gallon. You have any idea how far I can drive on the cost of an electric car battery? Battery cars are a joke. The Phev from Mitsubishi is the electric future. Internal combustion electric , like a locomotive drivetrain. Most efficient.
thats the engine what i dream long ago
Oh my god this is gonna be a pain in the ass to fix.
日産のエンジニアはつくづく頭がおかしいと思わされるよ。
圧縮比変えれば効率とパワーの両立ができるなんて机上では誰でも知ってるけど、具現化しちゃうんだもん。
最高だぜ。
上下死点の変化量とHDRGの可動域の減速比もよう考えられてる。これだけHDRGが動かれせればそりゃリニアに細やかに制御できるわけだ。
日本へもっと展開してほしい。
And let’s put all this amazing revolutionary technology in an engine and mate it to a cvt😢
Nice, high compresi for low speed, and low compresi for high speed
That is a lot of work for just 248hp. My wife's 2015 subaru wrx gets 269hp from a 2.0
2020: 2 Billions Cars Today .. Is absolute unsustainable.
Wow amazing.. 1 engine, can do efficien, or power.. awesome
VC- turbo is too good 👌🏼👌🏼👌🏼👌🏼👌🏼👌🏼
Parts for this motor is too expensive 🤑
But u have to admit, this is a pretty slick design
My mum would love a car like this
these might be our SR20's in 10-20yrs time..
The efficiency of any engine is measured in terms of torque and, definitely, not horsepower. The longer the con-rod , then , the greater is the leverage . That’s means, the higher is the torque. That’s, really, what matters.
NEW TECHNOLOGY! WICHCRAFT! BURNBURNBURN!!!
So many people here are caught by the dunning kruger effect thinking they're smarter than chartered engineers...
Cool concept. Im sure there will be bugs to be worked out in the first production years.
good engine but how about the reliability ? i like it. they put both the port injection & direct injection in that engine, it will fix the intake valve carbon build up problem that always happen with the GDI engine.
but i prefer high displacement non GDI-Turbo engine. small displacement turbo engine have shorter life span than N/A engine.
Does it just have two CR settings or does it move anywhere between the 8 and 10 CR? if u could tune it to stay at a certain compression ratio and turn up the boost might be a fun engine/car
I wish that car manufacturers make a car that friendly to mods and not affraid of hign horsepower
The only thing that I don't like about nissan is their CVT other than that, their engine is pretty reliable tho
I used to love Nissan back in the 90s but seems how they can't even build an automatic transmission right I can only imagine how bad this is going to be when it fails 🤗
How did you manage to eliminate the piston's lateral tension to the cylinder? 😮😮😮
Hello Friends!, Why do you say that lowering the compression ratio provides a boost of energy? I think the higher compression ratio the better is its efficiency and powering. What happen with the knock effect for higher compression ratios? it's necessary to use premium fuel?- Thanks!
I wonder if with power upgrades, will it influence the compression ratio by somewhat over powering that electric motor (somewhat, not entirely).
Now make a vc-vvt aka variable compression and valve timing.
Keren.. Tp sejauh mana 2nd kruk as nya bs nahan beban kompresi?
