You might have heard about high compression ratios, but what exactly are they, and what kind of effect do they have on an ...

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 ...

In a conventional piston engine, the compression ratio defines the relationship between the largest and smallest volume of a cylinder - when its piston is at bottom dead centre and top dead centre ...

Stock car racing engines are all about efficiency. That's because all the simple solutions for making power have either been maximized or eliminated by the rule book. You aren't allowed power adders ...

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: 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 ...

Mercedes' rivals succeed in securing a rule change following a pre-season technical row over engine performance.

Formula 1's governing body, the FIA, has announced a resolution to the sport's regulatory row over engine compression ratios, ...

Rivals push the sport’s governing body into a midseason tweak as a dispute over compression ratios spills from the garage to ...

IRVINE, Calif.—Despite rumors to the contrary, the internal combustion engine is far from dead. Recently we’ve seen several technological advances that will significantly boost the efficiency of ...

In December, it emerged that Mercedes had found a possible loophole in the rules that could lead to a performance advantage.

In a conventional piston engine, the compression ratio defines the relationship between the largest and smallest volume of a cylinder - when its piston is at bottom dead centre and top dead centre ...
