As a concept, the internal combustion engine is as old as dirt. To our luck, the ICE is still relevant nowadays thanks to engineering developments such as direct injection, cylinder deactivation, stop ...

A gasoline piston engine that can dynamically change its compression ratio —that is, the amount by which the piston squeezes the fuel-air mixture in the cylinder—has long been a holy grail of engine ...

You know what variable valve timing is. You're quite familiar with Honda's VTEC system. Now Infiniti has something new for you dive into, and it's all about changing an engine's compression ratio. The ...

Forget variable length intakes and variable valve timing, Infiniti is going all the way and introducing variable cylinder compression ratios. The new VC-T turbo engine automatically adjusts between a ...

Infiniti's new VC-T is groundbreaking in that it now offers an engine with a variable compression ratio, meaning it can be driven with fuel economy or horsepower in mind, giving the driver the option.

Since 1998, Nissan has been working on a new kind of engine that could realize many automotive engineers’ dreams: an engine with a variable compression ratio. This was Nissan going against the hybrid ...

With Infiniti having recently revolutionized internal combustion engines by the introduction of a variable compression ratio mill, we're here to take the time to zoom in on the tech introduced by the ...

Nissan engineers have reportedly been working on the engine concept for more than 20 years, and the company claims to have filed more than 300 patents protecting the design and associated technologies ...

Nissan’s variable-compression turbo (VC-Turbo) is a unique engine capable of variable compression adjustment. Unlike traditional engines, which have a fixed compression ratio, the VC-Turbo engine ...

It seems like every major automaker these days is using tricks like variable-valve timing – often in conjunction with forced induction – to eke better efficiency out of their engines while still ...

Harry Ricardo built the first known variable compression ratio engine as a test engine in the 1920s to study knock in aircraft engines. Variable compression ratio was achieved by raising or lowering ...
