Abstract:
A knocking control system comprises a knocking determiner device for determining whether or not knocking with a predetermined intensity or higher has occurred in a cylinder of a gas engine in each cycle; an integration variable calculator which adds to an integration variable CT when the knocking determiner device determines that the knocking with the predetermined intensity or higher has occurred, and subtracts from the integration variable CT when the knocking determiner determines that the knocking with the predetermined intensity or higher has not occurred; and a main controller for reducing a power output of the cylinder if the integration variable CT is not less than a threshold.
