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

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 ...

“Too little compression will usually result in unmet performance expectations. On the high side [too much compression] carries greater risk in tuning and potential component failure if appropriately ...

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