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 ...

Assuming a properly tuned engine, there are three factors that contribute to poor streetability: long cam duration, high compression ratios, and excessive cruise rpm. Since cam selection is largely ...

Now that we know how to calculate a compression ratio, let’s dig a bit deeper into what compression ratio physically means when applied to a cooling system. In reciprocating compressors, there must be ...

Nissan’s variable-compression turbo (VC-Turbo) is a unique engine capable of variable compression adjustment. Unlike traditional engines, which have a fixed compression ratio, the VC-Turbo engine ...

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

Jonathan loves just about anything with a motor and a steering wheel. As a kid, Jonathan collected any kind of toy car he could lay his hands on, and begged his parents to take him to the monster ...

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 ...

Apart from the very curious, not many people ask why diesel engines, compared to gasoline, run higher compression ratios. The argument is reasonably straightforward and starts with fuel ...
