Abstract
A regulation for a gas engine with a rotational speed probe for the crankshaft rotational speed, with a rotational speed-load-ignition angle-performance graph memory read out during each crankshaft rotation, with an ignition pulse generator controlled by the performance graph memory, with a lambda-probe, with a load probe, with a vacuum-controlled gas pressure adjusting device for the propulsion gas and with a flow-mixing device for the propulsion gas and the air. The invention provides a regulation for a gas engine which offers a full utilization of the possibilities of the gas engine above all in lean operation and in the partial load range. A rotational speed-load-lambda-performance graph (36) is provided for producing lambda-desired values. The lambda-desired values readied by the rotational speed-load-lambda-performance graph (36) are compared with the lambda-actual values under formation of a lambda difference value. For the adaptation of the ignition angle to the respective lambda actual value a lambda-difference value-load-ignition angle correction value performance graph (29) produces an ignition angle correction value which is added to the base ignition angle value of the rotational speed-load-ignition angle-performance graph (27), respectively, is subtracted therefrom.
