Abstract
The present invention pertains to a knock detection method for a gas engine, comprising the steps of retrieving a gas engine vibration signal; characterizing the retrieved vibration signal to obtain a characterized signal; detecting a knocking signal by comparing the characterized signal to a predetermined threshold signal; and qualifying the detected knocking signal as indicating a true knocking event or a false positive knocking event, based on at least one further gas engine operation parameter.
