METHOD FOR DETERMINING A VALUE OF A CHARACTERISTIC PROPERTY OF A PRESSURE REGULATING VALVE

摘要

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, a flow of the fuel flowing through the pressure regulating valve being set to a minimum and a control pressure (6) of the fuel being reduced (14, 132, 134, 136, 138) until the pressure regulating valve is opened, and at least one value for the characteristic being 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).
