Abstract: PROBLEM TO BE SOLVED: To provide a control device for a vehicular internal combustion engine optimizing overlap quantity control in an internal combustion engine equipped with a variable valve timing mechanism. SOLUTION: When the engine is gets in idling operation state, this device waits for stop of a vehicle. When the vehicle stops, the device sets overlap quantity of an intake valve and an exhaust valve small. Consequently, vibration of the engine in the vehicle stop state is reduced. Even if the engine is in idling operation, the overlap quantity is set greater than that in normal control if the vehicle is travelling. Consequently, engine load is increased by accelerator step-in action of a driver during vehicle travel or the like, and the overlap quantity is appropriately provided in a state where engine speed rises.

解决方案：当发动机处于空转运行状态时，该装置等待停车。 当车辆停止时，设备将进气门和排气门的重叠量设置得较小。 因此，发动机在车辆停止状态下的振动减小。 即使发动机处于怠速运转状态，如果车辆正在行驶，则重叠量设定为大于正常控制。 因此，通过驾驶员在车辆行驶等期间的加速器踏入动作来增加发动机负荷，并且在发动机转速上升的状态下适当地设置重叠量。 版权所有（C）2011，JPO＆INPIT

Abstract: PROBLEM TO BE SOLVED: To inhibit drop of cooling capacity of a cooling means by stopping exhaust gas supply when cooling capacity of the cooling means is at most a predetermined capacity.
SOLUTION: An internal combustion engine device controls an EGR valve not to supply exhaust gas to an intake side (S120, S160), if it is judged based on cooling water temperature Tw and ambient temperature Tout that cooling capacity of a cooling system is at most a predetermined capacity with which minimum capacity necessary to cool the engine can be secured even during execution of EGR (S130) when EGR execution conditions are met in operation of an engine (S110). Consequently, drop of cooling capacity of the cooling system can be inhibited. The EGR valve is controlled to supply exhaust gas to an intake side with keeping target EGR quantity R* calculated based on intake air quantity Qa (S140-S160) if it is judged that cooling capacity of the cooling system is the predetermined capacity or greater (S130). Consequently, the engine can be operated more appropriately thereby.
