Abstract

The invention relates to a method and arrangement for controlling the fuel metered to an engine and especially to a diesel engine. The engine includes a fuel pump drive by a shaft for which injection start and injection end is fixed by a corresponding control of the electromagnetically actuated valve. The drive pulses for pump-delivery start and pump-delivery end are generated in dependence upon the analog signal of an angle sensor.
