Abstract

냉기시동 직후의 무부하운전 시에 양호한 무부하운전 안정성을 확보하면서 배기성능도 향상시켜 배기중의 유해성분의 저감성능을 크게 높이는 것을 목적으로 한다.The object of the present invention is to improve the exhaust performance while ensuring good no-load operation stability during no-load operation immediately after cold start, and greatly increase the reduction performance of harmful components in the exhaust.

에어컨 스위치(22)가 오프이고(S1) 기관이 냉기상태에서 차량이 정지해 난기하고 있는 경우(S4,5,6)만, 압축기(15)만 강제적으로 온으로 해서 기관(8)에 부하를 가한 후 부하상태에서 회전수 제어가 가능하다고 판단된 경우에는 강제적으로 부하를 가한 상태에서 냉기무부하운전 제어를 행한다(S9, 10).Only when the air conditioner switch 22 is off (S1) and the engine is stopped and the engine is in a cold air condition (S4, 5, 6), only the compressor 15 is forcibly turned on to load the engine 8 with force. If it is determined that the rotational speed control is possible in the load state after the load is applied, the cold air load operation control is performed under the forced load (S9, 10).

When it is detected that the external load is inoperative, the external load operating means for forcibly bringing the external load into an operating state and the rotation speed control for controlling the no-load operation rotational speed to the target rotational speed by controlling the control amount to the auxiliary air control valve. Means and the rotational speed control means when the external load is brought into operation by the external load operating means. The no-load driving speed maintainability determining means for judging whether or not the down-operation empty number can maintain the target rotation speed, and the no-load driving speed maintenance determination means have determined that the target speed cannot be maintained by the operation of the external load. And an external load operation stop means for stopping the operation of the external load at the time of control. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
