Diesel engines do their hardest work in the toughest jobs, from highway semis to construction equipment, and the reason they can survive that punishment starts with how fiercely they squeeze the air ...

A.Here's a pressure-volume diagram for a combustion engine. Although rough, it is an approximation of the so-called air-standard cycle. '' Point (a) is at atmospheric pressure, after which the air is ...

You might have heard about high compression ratios, but what exactly are they, and what kind of effect do they have on an ...

From a gearhead's viewpoint—take that back, anybody's informed perspective—there's one guy who stands out as a catalyst in the art of automotive as we know it. Not talking about the caveman who ...

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 ...
