A method for evaluating the combustion chamber pressure in an internal combustion engine is described, in which the output signal of at least one cylinder pressure sensor and one crankshaft angle sensor is performed by the control unit of the engine. By analysis of the course of combustion chamber pressure over the crankshaft angle, characteristic pressure courses are obtained for certain valve control times. From these characteristic pressure courses, a conclusion can be drawn as to the valve control times "outlet opens", "outlet closes", "inlet opens", and "inlet closes", referred to the crankshaft angle. |
