An electronic control unit (30) provides closed loop control of the instant at which an injector (14) injects fuel into the cylinder (12) of a diesel engine (10). The unit (30) computes a desired instant of combustion from input values from a speed transducer (16) and a load transducer (24). Actual instant of combustion is given by a crank angle sensor (22) at the time when a detector (22) senses combustion. The error signal between desired and actual instants of combustion modifies a signal setting the advance of injection over ignition to determine the actual moment of injection by the injector (14). |
