Diesel fuel is a liquid product used as fuel in a diesel internal combustion engine, as well as in gas-diesel engines. Usually, this term refers to the fuel resulting from kerosene-gas oil fractions of direct distillation of oil.
Area of use:
The main consumers of diesel fuel are railway transport, lorries, water transport, military equipment and agricultural machinery, as well as, more recently, passenger diesel vehicles. In addition to diesel and gas-diesel engines, residual diesel fuel (diesel oil) is often used as boiler fuel, for impregnating leathers, in lubricating coolants for mechanical and quenching liquids during heat treatment of metals.
The main characteristics of the fuel:
There is distillate low-viscosity fuel – for high-speed engines, and highly viscous, residual fuel, for low-speed (tractor, ship, stationary, etc.) engines. Distillate fuel consists of hydrotreated kerosene-gas oil fractions of direct distillation and up to 1/5 of gas cracking and coking gas oils. Viscous fuel for low-speed engines is a mixture of fuel oil with kerosene-gas oil fractions. The heat of combustion of diesel fuel in average is 42,624 kJ / kg (10,180 kcal / kg).
