Method for assisting with heating a catalytic converter of an internal combustion engine |
摘要 |
The invention relates to a method for heating a catalytic converter which is arranged in the exhaust-gas path of an internal combustion engine with direct injection and spark ignition. In the method, a first fuel injection takes place in the intake stroke (E), whereas a second fuel injection begins in the combustion stroke after top dead center and prior to the spark ignition of the air/fuel mix. It is preferable for the second fuel injection to continue beyond the ignition instant until the pressure in the combustion chamber reaches the fuel injection pressure.
