Abstract:
An engine controller for controlling a compression ignition engine that powers a motor vehicle containing an accelerator pedal for accelerating the vehicle, the controller comprising:a processor for processing various data to develop fueling data for accomplishing governed fueling of the engine; wherein the processor contains programmed engine speed setpoint data representing engine speed setpoints correlated with combinations of accelerator pedal position data and engine load data such that the engine speed setpoint data, when processed with actual engine speed data to develop the fueling data, causes the engine to be load governed; the processor processes accelerator pedal position data corresponding to the position of the accelerator pedal and engine load data corresponding to the load on the engine to develop engine speed setpoint data; and the processor further processes the developed engine speed setpoint data and the actual engine speed data to develop the fueling data to cause the engine to operate within an envelope of prescribed speed subject to limiting to a maximum speed.
