Abstract
A method and a device for the optimization of the efficiency and/or exhaust-gas quality of lean burning Otto-cycle gas motors or gas motors with pilot-injection ignition. The fuel-gas quality is measured by a measuring device and the measured value is fed to an electronic controller which in turn controls the oxygen concentration in the exhaust gas and/or the timing of ignition or pilot injection.
