| 摘要 |
The invention relates to a method of operating an internal combustion engine operated on gasoline type fuels, more specifically on gasoline, wherein ignition of the fuel-air mixture is initiated spontaneously in at least one operational range of the engine, preferably in the part load range, and wherein a stratified charge is produced in the combustion chamber, preferably in the higher load range. In order to achieve in the simplest possible manner high exhaust quality for an internal combustion engine operated on fuel with poor ignition characteristics in the range of higher mean pressures as well there is provided that combustion is initiated by spontaneous ignition of the fuel in the full load range as well and that preferably the in-cylinder charge temperature is controlled throughout the load range by way of internal exhaust gas recirculation and that, in the full load range, the start of fuel injection occurs after top dead center.
