Infniti showcases the Innovative Variable Compression Turbo Engine
Quite often, in fact, if you turn around and look again the possibility is you may be seeing something new. A new product screaming new technology. And this exactly what is happening in the cars as well. They are laden with the tech that we may never see yet being sold to us with the make-believe that what we are experiencing is simply owed to that unseen ultra tech!
However the engines and the drivetrains are pretty complex parts of the vehicle, they are essentially machine itself. Still we’ve progressed in the classic internal combustion engines, largely in the form of petrol and diesel fuel powered vehicles. And now lately the drive system is shifting towards electric powered motors. And not only a large mindset is shifting towards electric, the fact of the matter is, they are clinically clean, environment-friendly, yet performance oriented as well.
Displayed for the first time at the 2016 Mondial de l’Automobile in Paris, Infiniti unveiled the all-new 2.0-liter VC-Turbo (Variable Compression Turbo) gasoline engine, the world’s first production-ready variable compression ratio engine. This four-cylinder VC-Turbo promises to be one of the most advanced internal combustion engines ever created.
With the ability to continuously transform, Infiniti’s VC-Turbo technology uses an advanced multi-link system to seamlessly raise or lower the stroke of the pistons, detecting the car’s driving condition and driver inputs, and instantly selecting the most suitable compression ratio.
The engine is able to offer any compression ratio between 8:1 (typical for high-performance engines) and 14:1 (used by many manufacturers for high efficiency).
The result is an engine that combines the power of a high-performance 2.0-liter turbo gasoline engine with the torque and efficiency of an advanced diesel powertrain – without the equivalent emissions – offering a compelling alternative to similarly-powered four-cylinder diesel engines. The VC-Turbo engine will be comparable to certain six-cylinder gasoline powertrains for performance, while significantly outperforming them in efficiency.
It took Infiniti, 20 years to develop and perfect the technology of VC engines. Utilizing the extensive Formula 1 experience. Infiniti set the target high with this little variable compression turbocharged four-cylinder engine is aimed to produce 268 horsepower, and the torque target is 287 lb-ft. The VC-Turbo engine is said to be so smooth, it requires no balance shafts – conventional four-cylinder engines require two. Removing them offsets the space occupied by the multi-link system
Here’s a video below that Infiniti believes, this presentation makes us understand the human-inspired technology easily.
The four-cylinder VC-Turbo engine achieves lower levels of noise and vibration than conventional internal combustion engines, particularly diesel, and is lighter and more compact than V6 units with comparable power outputs.
INFINITI’s VC-Turbo technology marks a significant leap forward for the internal combustion engine, joining other renowned powertrain innovations such as liquid-cooling, fuel injection, catalytic convertors, and turbocharging. The arrival of the variable compression ratio engine will establish new benchmarks for power, efficiency and emissions.
“Vehicle engineers believe that a breakthrough in internal combustion technology would come from mastering the variable compression ratio. INFINITI will be the first to bring this technology to the market in 2018. This new generation of powertrains will help our global growth and expansion of the INFINITI product portfolio.” Roland Krueger, President of INFINITI
