摘要： A control system (20) for a gas engine (1) including a controller (21) being configured to execute load equalization control such that a fuel feed amount corresponding to a higher-temperature cylinder of a first predetermined number which is selected to include a highest exhaust gas temperature, among cylinders which are controlled targets, is reduced, and a fuel feed amount corresponding to a lower-temperature cylinder of a second predetermined number which is selected to include a lowest exhaust gas temperature, among the cylinders which are the controlled targets, is increased; and a sum of the first predetermined number and the second predetermined number being less than the number of all of the plurality of cylinders so that there is a cylinder whose fuel feed amount is not changed.

摘要： PROBLEM TO BE SOLVED: To restrain deterioration in combustion performance by maintaining stable combustion in a main combustion chamber, in an auxiliary chamber-type gas engine having the main combustion chamber and an auxiliary combustion chamber. SOLUTION: This gas engine ignites fuel of the main combustion chamber 1 by injecting combustion gas from the auxiliary combustion chamber 2 via a plurality of nozzles 9 for communicating the auxiliary combustion chamber 2 with the main combustion chamber 1. The opening edges on the auxiliary combustion chamber side of the plurality of nozzles 9, are formed as curved surfaces 11. Curvature radii R of the curved surfaces 11 are set so that the rising or lowering temperatures of the opening edges on the auxiliary combustion chamber 2 side of the plurality of nozzles 9, become smaller than the rising or lower temperatures of the most easily temperature rising place except for the opening edges in an inner wall of the auxiliary combustion chamber 2.

摘要： A knocking control system 1 comprises a knocking determiner device 24 for determining whether or not a knocking with a predetermined intensity or higher has occurred in a cylinder 3 of a gas engine 2 in each cycle; an integration variable calculator 30 which adds 1 to an integration variable CT when the knocking determiner device 24 determines that the knocking with the predetermined intensity or higher has occurred, and subtracts 1 from the integration variable CT when the knocking determiner 24 determines that the knocking with the predetermined intensity or higher has not occurred; and a main controller 20 for reducing a power output of the cylinder 3 if the integration variable CT is not less than a threshold.
