METHOD FOR OPERATING A GAS MOTOR OR A DUAL-FUEL MOTOR OPERATED IN A GAS FUEL OPERATING MODE AND CORRESPONDING MOTOR

摘要

Method for operating a gas engine or a dual-fuel engine with several cylinders operated in a gas fuel operating mode, an ignitable mixture (4) of a gaseous fuel (10) and combustion air (8) being ignited and burned in the cylinders (1), and wherein the ignitable mixture (4) of the gaseous fuel (10) and the combustion air (8) is provided for the respective cylinder by the fact that combustion air (8), which via a combustion air line (7) in the direction of the cylinder (1) upstream of an inlet-side gas exchange valve (2) of the respective cylinder (1) is mixed with the gaseous fuel (10), which is metered in individually for each cylinder via a gas valve (14) assigned to the respective cylinder (1). A non-ignitable premix (9) consisting of the combustion air (8) and the gaseous fuel (10) is fed in the direction of the cylinder (1) via the combustion air line (7). The non-ignitable premix (9) of combustion air (8) and gaseous fuel (10) is metered individually for each cylinder upstream of the inlet-side gas exchange valve (2) via the gas valve (14) assigned to the respective cylinder (1) to convert the non-ignitable premix (9) of combustion air (8) and gaseous fuel (10) into the ignitable mixture (4) of combustion air (8) and gaseous fuel (10).
