In a method of operating a multi-cylinder Diesel engine in which fuel delivered by an engine-driven high-pressure pump is supplied to a high-pressure line from where it is admitted through injectors to the associated cylinders by an engine speed synchronous pulse and the pressure in the fuel line is determined by a pressure sensor at a certain operating point present during fuel delivery and, upon failure of the synchronous pulse, a pressure signal generated at this operating point is used to start the injection sequence with the activation of one of the injectors, and the time spans between subsequent operating points in the injection sequence are determined and, if a deviation between the time spans exceeds a limit value, another injector is selected for the start of another injection sequence, which is used as a new start of the injection sequence until the time spans between the various operating points in the high-pressure fuel supply lines which are a measure for engine speed are essentially the same. |
