Method for heating up a catalyst in combustion engines with direct fuel injection |
摘要 |
A method for heating up a catalytic converter in internal combustion engines having gasoline direct injection is presented and has the steps: shifting the ignition toward retard; checking whether the charge of the cylinders with air exceeds a pregiven threshold; and, dividing the fuel injection into two component quantities which are injected in advance of the ignition when the air charge exceeds the threshold.
