Definition - What does Diesel Fuel mean?
Any liquid fuel that is used in diesel engines is referred to as Diesel fuel. This fuel is specifically designed for diesel engines, where the fuel ignition happens without any spark due to the compression feature of the engine. Diesel fuel gets atomized in the combustion chamber, where it is mixed with air that leads to the production of the power in the engine. This fuel is ideally derived from petroleum (rock oil) by conducting fractional distillation. However, alternatives are being developed such as biodiesel, GTL diesel and BTL diesel. It is also known by many different names across the world such as distillate, DERV and petrodiesel.
Petropedia explains Diesel Fuel
Diesel fuel is a fractional distillate product of petroleum. This fuel is specifically produced for diesel engines. When used in a diesel engine, the fuel produces power when it is atomized and mixed with the air in the combustion chamber. This causes fuel ignition to take place without inducing any spark due to the compressed air and fuel injection. Due to its higher fuel efficiency, diesel fuel is preferred in thermodynamics and transport industry abroad because it has better performance as compared to normal petrol. There are many types of diesel fuel – petroleum diesel or petrodiesel, synthetic diesel such as biomass-to-liquid, coal-to-liquid or gas-to-liquid diesel and biodiesel.
