Abstract
A method for determination of the bulk modulus of fuels in a fuel system of a combustion engine () with a common rail injection system (), with a high pressure volume () including the high pressure side of a high pressure pump () and a fuel accumulator () with injectors () for injection of fuel into the cylinders of the combustion engine. The method including: first determining the volume of the high pressure volume by supplying a fuel with a known bulk modulus to the fuel system and by controlling the high pressure pump () so that it performs a pump stroke with the volume of the high pressure volume closed. The value of the determined volume is later used with another fuel in order to determine the latter fuel's bulk modulus.
