Diesel engine controlling method for motor vehicle, involves evaluating electrical resistance process for determination of combustion parameter, which signifies cyclic fuel combustion taking place in combustion chamber of engine
The method involves determining an electrical resistance process of a glow plug (5) extending in a combustion chamber. The electrical resistance process is evaluated for determination of a combustion parameter e.g. ignition point, which signifies cyclic fuel combustion taking place in the combustion chamber of a diesel engine. An actuator (2) is actuated depending on the determined parameter. A constant test current is fed into the glow plug for the measurement of an electrical resistance, where the glow plug is used as a temperature sensor. An independent claim is also included for an engine control system.
