- The new 2.0-liter VC-Turbo, which recently launched as a world's first technology in the all-new INFINITI QX50 crossover, replaces the previous-generation Altima's 3.5-liter V6, offering similar performance figures while providing 4-cylinder fuel economy. It will be available on the Altima SR and Platinum front-wheel drive grades.
World's first production Variable Compression Turbo engine
Designated as the VC-Turbo, the technology behind the new Altima powerplant was more than 20 years in development and represents a breakthrough in combustion engine design by continually adjusting its compression ratio to optimize power and fuel efficiency. It is projected to offer a double-digit percentage increase in fuel economy.
Assembled in Japan, the VC-Turbo changes its compression ratio seamlessly through an advanced multi-link system, continuously raising or lowering the pistons' reach to transform compression ratio - offering both power and efficiency on demand. A high compression ratio gives greater efficiency, but in certain applications poses the risk of premature combustion (knocking). A low compression ratio allows for greater power and torque and avoids knocking.
In operation, the 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.
As the angle of the multi-link arms changes, it adjusts the top-dead-center position of the pistons - and the compression ratio with them. An eccentric control shaft changes the compression ratio of all the cylinders at the same time. As a result, the engine capacity varies between 1,997 cc (for a low 8:1 ratio) and 1,970 cc (high 14:1 ratio). The transformative multi-link components are manufactured in high-carbon steel alloy.
The engine also utilizes two combustion cycles, with the electronic variable valve timing allowing the engine to switch between Atkinson and regular combustion cycles. This allows for greater efficiency and optimal performance as the compression ratio transforms.
Compared with the previous-generation Altima's 3.5-liter V6 engine, the 2.0-liter VC-Turbo requires less space in the engine bay. The integrated exhaust manifold in the cylinder head contributes to the compact engine packaging, improves turbo response and enables the catalytic converter to heat up quickly for lower emissions. The engine also contributes to lower NVH levels.
The VC-Turbo engine uses both multi-point injection and gasoline direct injection to balance efficiency and power in all conditions. Gasoline direct injection improves combustion efficiency and performance, and enables the engine to avoid knocking at higher compression ratios.
The multi-point injection system mixes fuel and air earlier, enabling complete combustion in the chamber for greater efficiency at low engine loads. The engine switches between both at regular engine speeds, with both sets of injectors able to work in conjunction under higher loads.
In addition, low-friction mirror bore coating contributes to a 44% reduction in cylinder friction, allowing the engine to rotate more smoothly. The coating is applied to the cylinder walls by a plasma jet, then hardened and honed to create ultra-smooth cylinder walls. And finally, a two-stage variable displacement oil pump raises the oil pressure as engine speeds rise and the compression ratio lowers.
Altimas equipped with the VC-Turbo (SR 2.0L and Platinum 2.0L grades) include a meter in the instrument panel's 7-inch Advanced Drive Assist Display so the driver can see, as well as feel, the control state of this unique technology while driving.

I work for Nissan. I was part of the team who launched the VC-Turbo in the 3cyl and 4cyl configurations. While this being an industry first mass production VC engine, something not even the Big 3 could get right, Nissan persevered and brought it to life. This engine has changed the game. Ford and GM are now trying to copy the engine and capitalize off a success by Nissan. Yes Nissan faced challenges with the motor at first. Many challenges. But our teams analyzed and trouble shooted and solved them as the came. This engine is a very precise engine. Unlike regular motors where tolerances can vary on a decent spec of hundreds of micons, this engine not so much. I've had the honor to build one of these VC by hand, and its a real experience. Nissan, setting an industry standard with breakthroughs once again. Just as Nissan done with their PR engine. Nissan engines continue to be the worlds most sought after motor.
For those who question the mileage life, I personally have a 2018 Altima with the 4cyl VC-TURBO and it hit 250,000 miles in 2023. The engine has minimal wear on it. Showing that once again the skilled teams at Nissan took an engine thought too difficult by the Big 3 to mass produce with a long reliable life span, and made it happen.
I'm amazed how one can lie about with such confidence. This shit of an myr engine literally fails after few thousands of kms use.
These engine's are under official investigation. " Nissan’s Variable-Compression Engine Failures Are Under Federal Investigation

Frequent engine knocking and metal shavings in oil pans. Yeah one heck of a success fk

I have a 2019 QX50 with this engine and a CVT transmission, because its a lease i dog walk that car, put 87 in it most its life, When i put 93 it takes off! ignored the break in period and went 2k miles over due on 2 oil changes, the car is also driven by my family and im constantly hard on the suspension and brakes, The car had its transmission replaced around 20k miles, the car now has 30k very hard miles, I also drove it without the intake half the time. Motor feels faster than ever especially when its 70 degrees F. or less, It makes like 300 crank hp especially because i make my own gas additives with Methanol and Toluene, a drop of nitro fuel, car spins all the way to 60, other than that I put straight 93 and 2 bottles of octane booster, I don't recommend it but that car has put up with a lot and it keeps pushing power with a little bit of rocker tick at idle when its cold, also gets pushed when its cold. I daily tf out of this car

Rotary engine: hello, first time?
All negative comments about reliability due to complexity are made by non engineers who would have said the same thing about vtec in the late eighties..
Try used a "vtec" from a brand that is not toyota/honda and see the shitstorm
It's not really that, it's just all the shit Nissan's on right now. CEO stealing/scandal. The really bad engineered CVT. That technically isn't Nissan's doing except the CEO decided to outsource that job. We just want Nissan to go back to the basic, "RELIABILITY" not coming out with another engineering gimmick, we know is going to fail. It's not like I'm not about progression, but let's get a stable footing. Honda's not the first variable valve timing, it was Fiat I believe. 🤔 they gave up on it because it wasn't cost effective and there was something to the engine they couldn't do back then. That they can now. Honda's more of the perfectionist and has several patents on that engineering marvel.
@@polentusmax6100 almost all cars have variable valve timing and i dont see where is the storm youre talking about... 🤔
I trust Honda to make a reliable engine a lot more than I trust Nissan.
Every comment about reliability/balance.....has been made by the unreliable/unbalanced. Coincidence??
Continually variable circumference wheels are on the next years model.
LOL I'm not sure if I would be willing to live in a world like that.
Independent research in engine technology by many universities, engine designers and smaller factories have shown but cannot sell their designs to larger car companies that a simpler 1.5-2.0L straight 6 or L6 with 10-16 degree offset crankshaft, variable boost, variable timing, passive combustion sparkplugs and 2 valve combustion chambers have proven a layout that is quieter, easier to build, easier to maintain, more efficient pulses therefore better economy, torque and acceleration than any complicated 4 cylinder design. However complexity destroys the profits once made by smaller third party aftermarket companies.
Love You NISSAN .👌
heartily Compliment by Indian.😘
Cool concept. But now a 4clyinder will have the same weight of a V8, and have same number of rods?! With less power?...I understand it's a new concept, and I would like to future models and see the improvements.
Главное чтоб писали о применении эдакой технологии большими буквами. На что только не пойдут чтоб уменьшить ресурс в угоду псевдотехнологичности.
А какой у этого двигателя ресурс?
По мне это не уменьшение а увеличение ресурса потомучто на поршневые стенки юбку нагрузка уменьшилась плюс вибрация дизбаланс уменьшилась в чем здесь плохого
@@dvikharev чем больше деталей в двигателе, тем больше возможностей для поломки. Учитывая что сейчас на рынке автомобили с классическим колен валом без наворотов бывает не доезжают до 100тысч пробега из-за проблем с корректировщиком фаз распределения, катализатора или непосредственного впрыска топлива, то это я расцениваю как дополнительный фактор риска
@@dvikharev согласен что на картинке вроде всё прекрасно. С перекладкой поршня и уменьшением вибраций всё просто шикарно... Ремонтопригодность мне кажется пострадает, а ремонт принесёт херовый русский бензин. По технологии тут всё продумано хорошо.
@@tomahawk648 по поводу херового российского бензина: так изменение степени сжатия как раз расширяет всеядность этого двигателя, потому как обычные движки не могут уменьшить степень сжатия, а этот двигатель уменьшил степень сжатия и нет проблем с детонацией. Также в этом двигателе из за более удачной (вертикальной) нагрузки поршня после воспламения износ цилиндра и юбки поршня сведены к минимуму.
I see everyone knocking the extreme complexity of this engine, but what Im concerned about is why did they even make this? How would this engine benefit the consumer in any way?
Car companies are making cars for no-brainers. Assist of this, assists of that, systems, helpers, everything automatic. Now even a monkey can drive a car. Here You can see a turbocharger lag and spool assist for people that don't know how to operate and what to expect from a turbocharged engine. They treat customers as idiots.
Well, high compression engines have many benefits in terms of power, torque, fuel efficiency. That’s why many car makers have pushed the envelope of high compression engines going as high as 13:1 or even 14:1. However, high compression doesn’t work so well with turbochargers as it increases the risk of preignition. So this technology solves the problem of allowing high compression at times when there’s low boost from the turbo and low compression when there’s higher boost from the turbo. That gives you the best of both worlds of power and fuel efficiency.
And it seems to have worked. The little 3 cylinder turbo in the Rogue feels energetic when pushed, but it returns the best gas mileage out of any non-hybrid in its class. I think this technology coupled with a hybrid system would be the next logical step if this technology proves to be reliable in the long term.
Saab developed a more simple system in 2000, but GM shelved it.
Now that fancy new engine design needs to be driven 300,000 or more miles in a 10 years or more time span and then we will find out if the new design is superior to the conventional engine designs.
Those parts are heavy, making this kind of engine heavier. Range extender like 1 stroke engine is more efficient in making power for EV vehicle.

I remember when Nissan engines were simple easy to fix I'm not buying it

Just fucking send it.
Looks so cool.
It's a good idea but I can't wait to see all the issues that arise
Why low compression if just make it a fixed at high compression without extra moving parts?
Некоторые говорят мало ресурса и то и сё. Но современному двигателю надо быть экологичным, а значит и экономным. То что ремонтопригодность будет никакая, это не беда, как и не ремонтопригодные современные смартфоны, типо одноразовые. Авто не должен быть вечным, он должен быть рациональным, безопасносным и главное эколгичным, что бы кто бы не говорил. Маркетология тут ещё на втором месте. Сейчас другие приоритеты. Но это всё для России не очень подходит, из-за суровых климатических условий, но всё же.

I'm pro electric cars 110kw max.
Complicated yes... but if you see how it's designed, the stressed that kill conventional engines are not present/as pronounced in this engine. So despite the extra complications, it's still an even more efficient and powerful engine.
If you want complicated?!? Look into Saab's attempt in the late 80s, early 90s for their variable compression engine. Wooo what an abortion that piggy was.
Sadly, our society is that of a "throw away" mentality, so when it breaks they'll just get a new one. Nevermind making something last, and then to be able to repair it, instead of replace.
