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

With the combustion chamber being the root of all horsepower, it only makes sense that you start spec'ing an engine build there. One of the key variables in engine building is compression ratio, or ...

Pretty simple question actually (or so my ignorant mind thinks): At what compression ratio would an engine benefit from higher octane fuel? The Focus I drive is just over 10:1, and I've heard some say ...

Since the detonation tendency of the fuel is the limiting factor in the development of power and the efficiency with which the fuel can be burned, the author considers this phase of the subject .with ...

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 ...

Opinions are divided about interpretations of compression ratio limits for engines in 2026. Controversies in the new season ...

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