Verfahren zum Betrieb eines Ottomotors mit Direkteinspritzung |
摘要 |
In a method for operating a spark ignition engine with direct fuel injection, in which the engine is operated either with charge stratification or with a homogeneous charge, the open and/or closed positions of the inlet and exhaust valves are controlled with variable timing depending on the engine operating condition. The timings are determined on the basis of basic timing settings, which are provided in basic timing performance graphs for operation with charge stratification and homogeneous charge operation. The basic timing settings are modified by means of correction values to raise the temperature of the exhaust gas for internal exhaust-gas recirculation and for causing a movement of the charge in the cylinders. |
