Steuerungsvorrichtung und Steuerungsverfahren für Verbrennungsmotoren

摘要

The control unit includes an arrangement for modifying the lag time period corresponding to the functioning state of the Electronic Control unit (16) for fixing the quantity of control corresponding to the torque reduction control during the period of switching between the two combustion states. The control unit is for an IC engine (10) having an exhaust gas recirculating unit EGR (14) between the exhaust (13) and an inlet (12), regulating the switching between a stratified charge mode and an uniform combustion mode by regulating the degree of opening of the EGR valve (20), in such a manner as to control the torque reduction of the IC engine.
