Big rigs and commercial haulers often utilize heavy-duty truck engines to move massive loads across long distances.

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 ...

Four-stroke diesel engines operate in a similar fashion to their petrol counterparts, but there are a few major differences worth knowing about... Most conventional automotive diesel engines make use, ...

Compression ignition basically is the term that is used for describing the manner in which diesel engines function. It happens when intake air—which often is combined with recirculating exhaust gas—is ...

A gasoline piston engine that can dynamically change its compression ratio —that is, the amount by which the piston squeezes the fuel-air mixture in the cylinder—has long been a holy grail of engine ...

Any certified gearhead knows that diesel engines do not use spark plugs. But why not? If power in an engine is created by combustion or explosion of flammable liquids, won't a spark plug in a diesel ...
