Internal combustion engine e.g. diesel engine, operating method for motor vehicle, involves adjusting actuator by regulator depending on regulating parameter, and using physical parameter as regulating parameter

摘要

The method involves adjusting an actuator by a regulator depending on a regulating parameter by comparing a reference value for the regulating parameter of the actuator with an actual value for the regulating parameter. A physical parameter influenced by the actuator is used as the regulating parameter. A reference value for suction pipe pressure (22) is determined from a reference value for combustion chamber pressure at a reference angle in a lower dead point. The reference value for combustion pressure is determined from a reference value for gas mass (11) in a combustion chamber (10).
