Liquid petroleum products. Determination of ignition delay and derived cetane number (DCN) of middle distillate fuels by combustion in a constant volume chamber1 Scope This European Standard specifies a test method for the quantitative determination of ignition delay of middle distillate fuels intended for use in compression ignition engines. The method utilizes a constant volume combustion chamber designed for operation by compression ignition, and employing direct injection of fuel into compressed air that is controlled to a specified pressure and temperature. An equation is given to calculate the derived
