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 ...

Performance diesel engines are usually the realm of European automakers, but the highest-revving diesel actually comes from ...

Compression in a diesel engine is essential for effective and efficient performance. And when compression is lacking, damage can result. That’s why it’s imperative to know whether your engine’s ...

Gasoline and diesel engines are very different. The former rely on spark ignition while the latter use compression ignition. Diesel engines typically run at much higher compression ratios than ...

Diesel engines and gasoline engines are so fundamentally different that it’s possible to do real damage simply by filling up your car with the wrong fuel. Converting a diesel engine to actually ...

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 ...

There are several types of engine compression testers. Be sure to use the correct type for your specific engine, otherwise ...

Ethanol-diesel blends represent a promising route to reduce carbon intensity and particulate emissions from compression ignition engines while utilising existing infrastructure. By incorporating ...

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 ...
