ABSTRACT:
A motor vehicle (20) has a diesel engine (22) and one or more sources (30, 36) providing data relevant to operations of the vehicle that are external to the engine but potentially influential on fueling of the engine. An engine control system (24) processes data according to an all-speed governing strategy for controlling engine fueling to develop all-speed governed fueling data (MFGOV) that sets engine fueling when a data input to the engine control system from the one or more sources discloses no need to influence engine fueling. When the data input from such one or more sources discloses a need to influence engine fueling, that data input causes engine fueling to be set by a strategy other than the all-speed governing strategy, a torque speed control strategy (54) in particular.
