Abstract (en)
[origin: WO2012010383A2] The invention relates to a method for determining a characteristic for a pressure regulating valve of an injection system, by means of which fuel is injected into an internal combustion engine, wherein a flow of the fuel flowing through the pressure regulating valve is set to a minimum and a control pressure (6) of the fuel is reduced until the pressure regulating valve is opened, and wherein at least one value for the characteristic is formed from a difference of a value for the control pressure (6) at which the pressure regulating valve opens and a reference value for the control pressure (6).
