Every car engine has quite a few details, ranging from cylinder count to compression ratios. How does changing the compression ratio affect the engine?

As you may know, an engine's compression ratio is directly linked to its combustion efficiency. All else being equal, higher-compression engines tend to make more power while offering better fuel ...

Nissan brought the first, and only, variable-compression engine to market. But its future doesn't look bright. Complexity in ...

A.Here's a pressure-volume diagram for a combustion engine. Although rough, it is an approximation of the so-called air-standard cycle. '' Point (a) is at atmospheric pressure, after which the air is ...

From June 1, the FIA will impose tougher tests on F1 power units in an attempt to clamp down on the compression ratio saga, ...

Compression: An automotive term used by everybody, forever. Let's get into some detail and maybe develop a better understanding. Pressure, and more pressure: It's a must-have to produce power within ...

Increasing an engine’s compression ratio is a proven way of unlocking extra horsepower, but there’s a point of diminishing returns. The team at Garage 54, the Russian mechanics who built a V16 using ...

At first glance, the concept of engine compression is simple enough:It's the ratio of the volume of the combustion chamber and bore when thepiston is at bottom dead center (BDC) versus when it is at ...

Compression in a diesel engine is essential for effective and efficient performance. And when compression is lacking, damage can result. That is why it’s imperative to know whether your engine’s ...

GM has filed a patent application for so-called “Multilink Cranktrains with Combined Eccentric Shaft and Camshaft Drive System for Internal Combustion Engines.” The system is designed to provide ...

Infiniti's new Variable Compression Turbo is the centerpiece of this crossover. Variable compression engine sounds like something you’d hear from a super villain describing his latest contraption. At ...

Compression ignition basically is the term that is used for describing the manner in which diesel engines function. It happens when intake air—which often is combined with recirculating exhaust gas—is ...
