The internal combustion engine includes a knock sensor which can sense the seating sound of the intake valve and/or the exhaust valve.
The invention relates to a method and a device for error detection or diagnosis, for use in a multicylinder internal combustion engine with a knock sensor.
In order to detect the stand-alone mode operation, a signal (30, 64) of a knock sensor (28) of the internal combustion engine (12) is evaluated.
To this end, a measurement signal of a knock sensor (2) is evaluated during a combustion inside a cylinder of an internal combustion engine in order to determine whether the combustion involves knocking or not.
As a result, the invention provides that the combustion noise is detected with the aid of a knock sensor (12) and is analyzed using an algorithm whereby enabling the obtained signals to be classified in statement intervals.
The invention relates to a method and device for the control of knocking in a multi-cylinder internal combustion engine with a guide cylinder (Z1) to which a knocking sensor is allocated.
