This engine, capable of operating on both LNG and diesel, represents a significant step towards decarbonisation in the ...

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 ...

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

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 ...

The compression ratio can vary from 8:1 all the way up to 14:1, and Infiniti says this yields "an engine that combines the power of a high-performance 2.0-liter turbo gasoline engine with the ...

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

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 ...

Static compression is what engineers, engine builders, and even do-it-yourselfers dial in to an engine build. Basically, it's the exact compression ratio formulated into engine construction in a ...

Now Porsche is working on just such an engine, revealed in the form of a newly-published patent, which will be able to alter its compression ratio.

The MCE-5 engine from MCE-5 Development in Lyon, France varies its compression ratio and uses a combined gear and rod-crank mechanism.

The compression ratio describes the volume of an engine cylinder when the piston is at the top versus the bottom of its travel.

The latest miracle is Nissan’s VC-T engine, the first production engine with the ability to physically alter its compression ratio.
