摘要：AbstractAs an effective device to improve emissions for gasoline engine, the catalyst has been widely applied in vehicles. Long time fuel cutoff condition will lead to the increase of oxygen content in catalyst. To improve the emission performance after fuel cutoff recover, a control method of purging oxygen in catalyst is proposed in this paper. The model of oxygen storage and purge is built. Then a state machine of oxygen purge is designed based on this model. Finally, the strategy is applied on the real vehicle test. Through the test results under theNEDCdriving cycle, it is shown that the proposed method of catalyst oxygen purge can effectively reduce the emission forGDIengine.
