OPERATING METHOD FOR A GAS MOTOR WITH A LEAN MIXTURE AND GAS MOTOR WITH A LEAN MIXTURE

The invention relates to an operating method for a lean-burn gas engine (1) with multiple cylinders (2, 3, 4), wherein the lean-burn gas engine (1) comprises cylinder-individual gas metering, cylinder-individual combustion progress detection, wherein the lean-burn gas engine (1) is controlled by a control device (5) such that a combustion duration of the individual cylinders (2, 3, 4) is regulated cylinder-individually by the control device (5) through a variation of an ignition timing, and such that the control device (5) regulates the ignition timing cylinder-individually in such a way that all cylinders (2, 3, 4) are equalized with respect to their conversion point such that a defined conversion point is reached at a defined crankshaft angle.
