High Speed Diesel (HSD) is manufactured between 200 °C and 400 ° C from fractional distillation of crude oil, resulting in a mixture of carbon chains and consisting of saturated hydrocarbons. HSD is used as a fuel in medium and high speed compression ignition engines (operating above 750 rpm) in commercial vehicles, stationary diesel engines, locomotives and pumps etc.
Use of HSD
Trucks
And now passenger cars
Power generation
Locomotives
Pump sets in agriculture
Properties of High Speed Diesel:
Flash Point : – The flash point of diesel is a minimum of 33°C for automobiles.
Flame Length :– Diesel oil should not produce a flame length of more than 18 mm.
Cetane Number :– Knocking quality of diesel oil is measured by cetane number.
