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 ...

A NEW BARRIER to higher compression ratios has recently become apparent — engine rumble! This phenomenon will prevent further increases in compression ratio unless corrective measures are taken. This ...

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

The temperature of the refrigerant entering the compressor’s cylinder also has an effect on capacity, but for this article, we’ll focus on pressures. COMPRESSION RATIOS Both the high- and low-side ...

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 ...
