A method for controlling a fuel injector of a diesel engine having a predefined control time from a control start, in which a setpoint value of a combustion start of a combustion chamber charge of the diesel engine is ascertained. The method is characterized in that an ignition delay between the control start and the combustion start is estimated from performance parameters of the diesel engine using a computing model, and the control start is formed on the basis of the setpoint value of the combustion start and the estimated ignition delay. A control unit controls the sequence of the method.

Method for controlling a fuel injector of a diesel engine

A method and a device for controlling an internal combustion engine in which a combustion chamber quantity characterizing the combustion process is ascertained on the basis of input quantities. This takes place using a polytropic exponent. The polytropic exponent is ascertained on the basis of performance characteristics of the internal combustion engine.
