Abstract
In a diesel engine control system, an intake air density compensation system is provided for compensating the control amounts of a diesel engine in accordance with the variations of intake air density. The variation amount of the intake air density is indicated by the difference between the control input amount obtained in accordance with an ignition timing closed loop control and the control amount obtained in accordance with an ignition open loop control. The various control amounts of the diesel engine is compensated on the basis of the difference so that the diesel engine is ensured to be optimally operated irrespective of the variations of intake air density.
