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

Dual-fuel combustion in compression ignition engines combines a high‐reactivity pilot fuel, typically diesel, with a lower‐reactivity secondary fuel such as natural gas, methane, ethanol or hydrogen.

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 ...

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 ...

Nissan's innovative variable compression engines were a fascinating innovation when they were first revealed, but the jury is still out on whether or not the combustion technology will stick around. A ...

We may receive a commission on purchases made from links. Developed and patented by Rudolf Diesel, the diesel engine was designed to offer higher efficiency than the widely-used Otto gas engine, using ...

Nanoparticle additives have emerged as a transformative approach to enhance the performance and emissions profile of biodiesel in compression ignition engines. By exploiting the high surface-to-volume ...

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 other forms of racing where the cars are designed to be equal (e.g. Race of Champions). F1 and most other series are not that. As others pointed out, there is a long storied history of ...
