摘要：On the start of a fuel cut, valve timing is moved to increase the amount of internal EGR (FIG. 2C). A throttle opening degree (TA) is controlled to be not less than a basic idle opening degree (TA0) until a sufficient amount of internal EGR is obtained, and at the time when the sufficient amount of internal EGR is achieved, the throttle opening degree (TA) is restricted to be not more than the basic idle opening degree (TA0) (FIG. 2D). In a fuel cut in low rotation speed, the amount of increase in internal EGR is made less than that in a fuel cut in high rotation speed and the amount of restriction of the throttle opening degree (TA) is reduced. ® KIPO & WIPO 2007
