Method for detecting leakage of injector of injection system of internal combustion engine, involves operating injector at two different values of rail pressure, where no-load operating demand of injector is reviewed
Method for detecting leakage of injector of injection system of internal combustion engine, involves operating injector at two different values of rail pressure, where no-load operating demand of injector is reviewed
The method involves operating an injector (12,14,16,18) at two different values of a rail pressure, where a no-load operating demand of the injector is reviewed. A leakage of the injector is detected by a change in the no-load operating demand. The no-load operating demand is reviewed by a no-load operating controller (22) of an internal combustion engine. Independent claims are also included for the following: (1) an arrangement for detecting a leakage of an injector of an injection system of an internal combustion engine; (2) a computer program; and (3) a computer program product.
