Abstract
A method for determining the proportion of gaseous working medium in a cylinder of an internal combustion engine includes opening an injector so as to feed fuel directly into the cylinder. The injector is connected to a fuel line in which a pressure sensor is arranged. The pressure in the fuel line is measured when the injector is open. The proportion of gaseous working medium in the cylinder is determined in conjunction with an association between the measured pressure in the fuel line when the injector is open and the proportion of gaseous working medium in the cylinder.
