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 ...

Broadly speaking, the higher the compression ratio, the greater the engine’s thermal efficiency (that is, the more mpg you get). So why not run the highest compression ratio possible all the time?

N issan’s original variable-compression powerplant is an absolute marvel of engineering. This little four-cylinder wonder is ...

But too high a ratio causes knocking—premature detonation of fuel-air mixture during the engine's compression stroke caused by high cylinder temperatures.

This lowers the compression ratio to 8.1, but because the turbocharger kicks in at the same time, the engine's power output increases.

Infiniti's VC-T is the first variable compression-ratio engine to enter production.

Read on as we list ways to figure and measure your compression ratio, total piston volume, and choosing the best pistons. Read on for more details along with photos only in Mopar Muscle Magazine ...

The compression ratio isn’t just a number: it’s one of the greatest determining factors in engine building. Compression ratio determines the type of fuel, how much boost, and has a significant ...

The world's first production continuously variable compression engine setup, dubbed VC-T, will be first used in the Infiniti Q50 in 2018.

An interesting patent has been filed by Toyota for an engine with variable compression.The patent is for an engine with variable length connecting rods.The connecting rod features two hydraulic ...

Infiniti has a variable compression ratio engine, but Mazda has a different solution. It's set to release the first commercial compression-ignition gasoline engine, dubbed SkyActiv-X.
