Abstract:
A gas engine system controller: calculates a delay calculation value of a knocking occurrence ratio; determines a primary target ignition timing; sets the primary target ignition timing as a current ignition timing if the occurrence ratio difference is positive and an ignition timing does not exceed a converted value of a first advance rate; determines whether a rapid advance condition is satisfied if the occurrence ratio difference is positive and the ignition timing difference exceeds the converted value of the first advance rate; sets a secondary target ignition timing as the current ignition timing if the rapid advance condition is not satisfied, the secondary target ignition timing obtained by adding the converted value of the first advance rate to the previous ignition timing; and determines the current ignition timing so as to achieve a second advance rate greater than the first advance rate if the rapid advance condition is satisfied.

Claim (Index 1):
A gas engine system comprising:\n a gas engine including at least one cylinder that combusts therein an air-fuel mixture of a fuel gas and air; an ignitor provided in the cylinder; a pressure sensor that detects a pressure in the cylinder; and a controller that controls the ignitor, wherein the controller:\n calculates a delay calculation value of a knocking occurrence ratio based on the pressure in the cylinder, which is detected by the pressure sensor; \n determines a primary target ignition timing based on an occurrence ratio difference obtained by subtracting the delay calculation value of the knocking occurrence ratio from a target occurrence ratio, such that an ignition timing is advanced if the occurrence ratio difference is positive, and such that the ignition timing is retarded if the occurrence ratio difference is negative; \n sets the primary target ignition timing as a current ignition timing if the occurrence ratio difference is positive and an ignition timing difference obtained by subtracting a previous ignition timing from the primary target ignition timing does not exceed a converted value of a first advance rate; \n determines whether or not a rapid advance condition is satisfied if the occurrence ratio difference is positive and the ignition timing difference exceeds the converted value of the first advance rate; \n sets a secondary target ignition timing as the current ignition timing if the rapid advance condition is not satisfied, the secondary target ignition timing being obtained by adding the converted value of the first advance rate to the previous ignition timing; \n determines the current ignition timing so as to achieve a second advance rate greater than the first advance rate if the rapid advance condition is satisfied; and \n controls the ignitor such that the ignitor ignites the air-fuel mixture at the current ignition timing.
