Abstract
A method for determining a characteristic for a pressure regulating valve of an injection system is described, using which fuel is injected into an internal combustion engine, in which a flow of the fuel which flows through the pressure regulating valve is set to a minimum and a control pressure of the fuel is reduced until the pressure regulating valve is opened, and in which at least one value for the characteristic is formed from a difference between a value for the control pressure, at which the pressure regulating valve opens, and a reference value for the control pressure.
