Diesel engines do their hardest work in the toughest jobs, from highway semis to construction equipment, and the reason they ...

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 ...

We might be covering ground that's well trampled for many, but the static compression ratio of an engine is simple to understand: it's all the volume of a cylinder above the compression ring at Bottom ...

You've heard the term compression ratio before, but have you ever wondered exactly what it means? Well, it's time to explain exactly what compression ratio is, and why every carmaker is now obsessed ...

Dim’s fascination with cars began when he was just six. Born into a family of car enthusiasts and racing drivers, he started learning basic mechanics and driving from an early age. While he loves ...

One of the key variables for an internal combustion engine is its compression ratio. This is the ratio of the maximum volume within the cylinder (when the piston is at bottom dead center) and the ...

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