Vehicle with reduced emission of harmful component |
摘要 |
An amount of oxygen accumulated in a catalytic converter after an engine stop by discontinuing a fuel supply to an engine is controlled to be within a preset range by controlling an engine speed into a preset range, controlling an engine revolution phase into a preset range, feeding air into the catalytic converter until the accumulated amount of oxygen becomes saturated, and controlling a catalytic converter temperature into a preset temperature range. Increase of an appropriate amount of the fuel at re-starting of the engine may prevent oxygen from deteriorating the NOx removing function without degrading an emission and the fuel efficiency.
