Method for Operating a Gas Engine or a Dual-Fuel Engine Operated in a Gas Fuel Operating Mode and Corresponding Engine

摘要

A method for operating a gas engine, or a dual-fuel engine operated in a gas fuel operating mode, the gas engine having a plurality of cylinders, structured to withstand ignition and combustion of an ignitable mixture of a gaseous fuel and combustion air, includes: preparing a non-ignitable premixture of the combustion air and the gaseous fuel; conducting the non-ignitable premixture toward the cylinders; adding further gaseous fuel to the non-ignitable premixture upstream of an inlet-side gas exchange valve via a gas valve assigned to a respective cylinder, so as to convert the non-ignitable premixture into the ignitable mixture; conducting, via the combustion air line, the ignitable mixture toward the cylinders; and providing the ignitable mixture to the respective cylinders.
