Nissan please put the extra effort into the next revision of this engine and address these two issues.
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?
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 💪🚗🚗
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.
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!
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
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.
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.
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.
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......
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.
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!
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.
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.
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
@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.
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.
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
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.
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.
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.
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!
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).
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
im with you on that but you are aware that Toyota, Honda , VW, Audi, and more have CVT now. and alot of Hondas CVT are having major issues specially toyota and there hybrids and corollas. NIssan was one of the first to bring it out yea.
@@robacejr Not sure about your common CVT used in most other popular car manufacturer's products because the Infiniti QX AWD Turbo's all use a rear wheel transmission double clutch drive system - not the usual competitions CVT at all, as you suggest? Also Infinity guarantee their great products with one of the very best 72 month warranties too? I think y'all need to study the Infinity QX AWD VC-T series a bit more before making fools of yourselves in public. Infinity are making great AWD SUV products now. Anyway even the Nissan rogues cvt transmissions you seem to be hung up on, are reliably tested to 200,000 + miles just the same as Toyota Mazda Honda and all the other cheap popular cars. Except Nissan have five times the experience at it.
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
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
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.
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.
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.
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.

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.
