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 ...

Cylinder head milling has long been known as one of the shortest and easiest routes to increased performance. A few thousandths of an inch carefully machined from the surface of the head will increase ...

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 ...

Diesel engines are different from gas engines in numerous ways, including their use of high compression ratios. Here's why ...

Formula 1’s next-generation power units are not even on the grid yet and they are already reshaping the competitive landscape. At the heart of the storm is a seemingly dry technical detail, the ...
