摘要： An object is to prevent an engine from entering an unstable combustion state such as misfire upon recovery, by halting or reducing gas fuel for a cylinder in which knocking is occurring, and then increasing the gas fuel again to appropriately perform a recovery control upon recovery to the optimum operation. A combustion control device for a gas engine includes: a knocking determination unit 49 configured to determine occurrence of knocking of each of cylinders; a knocking reduction unit 55 configured to halt or reduce supply of gas fuel to a cylinder in which the knocking is occurring and reduce supply of the gas fuel to other cylinders in which the knocking is not occurring; a first recovery unit 57 configured to recover a state where the gas fuel is halted or reduced in the cylinder in which the knocking is occurring; and a second recovery unit 59 configured to recover a state where the gas fuel is reduced in the other cylinders which are not the cylinder in which the knocking is occurring. A recovery time of the first recovery unit 57 is shorter than a recovery time of the second recovery unit 59, and recovery of the cylinder in which the knocking is occurring is performed as a priority.
