摘要： An arrangement and a method for calibration or monitoring a combustion process in a combustion engine, wherein an injection device injects fuel into a combustion chamber of the combustion engine. A noise-detecting sensor at the engine detects a parameter which derives from the noise generated during the combustion process. A control unit receives signal values representing the parameter from the sensors and receives information on the rotation position of a crankshaft in the combustion engine. The control unit determines the crankshaft position when the fuel is injected into the combustion chamber. Thereafter the injection device can be calibrated. Detecting the noise from combustion also makes it possible to assess whether combustion takes place at the intended time.
