摘要： The invention relates to an additional process for the spark advance adjustment. This process is used for the tight adjustment of the spark advance angle depending on the structure of the fuel molecules from at least one mapping. This adjustment covers the entire operation range of the engine. This process reduces the pollutant emission when the engine is cold, as soon as the engine starting and stabilisation phase when the engine control and adjustment systems are not in a closed adjustment loop yet. The spark advance adjustment can also be used for operation at the rattle boundary during high load operation and at the engine full load.
