GAS ENGINE CONTROL APPARATUS AND CONTROL METHOD

摘要

PROBLEM TO BE SOLVED: To achieve both control of knocking and improvement in efficiency.

SOLUTION: A control apparatus 100 of a gas engine 1 includes: a water injection means 14 for injecting water toward an inside of a cylinder 4 of the gas engine 1; a water injection control means 56 for controlling the water injection means 14; and a knocking occurrence ratio measuring means 45 for measuring a measurement value RM of a knocking occurrence ratio in the cylinder 4. The water injection control means 57 controls the water injection means 14 such that an amount of the water injection toward the inside of the cylinder 4 is set on the basis of a deviation between the measurement value RM and a target value RT.
