Control time reporting process for variable gas exchange valve system involves recognizing operation of control valve from signals of structure-borne noise sensor

The control time reporting process for the valve system (1) involves controlling the gas exchange valves by at least one control valve (MV1, MV2). There is at least one structure-borne noise sensor (70) to detect structure-borne noise. One or more operations of the control valve are detected from th...

Beschreibung
Zusammenfassung:	The control time reporting process for the valve system (1) involves controlling the gas exchange valves by at least one control valve (MV1, MV2). There is at least one structure-borne noise sensor (70) to detect structure-borne noise. One or more operations of the control valve are detected from the sensor signals, and depending on at least one detected operation of the control valve, the controlled times of the gas exchange valves are reported. Verfahren und Vorrichtung zur Ermittlung von Steuerzeiten variabel gesteuerter Gaswechselventile, wobei die Gaswechselventile durch mindestens ein Steuerventil (MV1, 2) angesteuert werden und wobei mindestens ein Körperschallsensor (70) zur Erfassung von Körperschall vorgesehen ist, wobei aus den Signalen des Körperschallsensors (70) eine Betätigung des Steuerventils (MV1, 2) erkannt wird und in Abhängigkeit mindestens einer erkannten Betätigung des Steuerventils Steuerzeiten der Gaswechselventile ermittelt werden.
