Diesel engine fuel is mainly diesel, usually light diesel for high-speed diesel engines; light diesel or heavy diesel for medium and low-speed diesel engines.
Diesel engines use fuel injection pumps and injectors to inject fuel into the cylinder at high pressure, and the injected fuel is in the form of mist and is mixed and burned with air.
Therefore, diesel engines can be used with poorly volatile heavy fuels or inferior fuels, such as crude oil and residual oil.
