Abstract: In a system for controlling an internal combustion engine, first opening determination of determining whether to open an air bypass valve 22 on the basis of a compressor flow rate (target compressor flow rate QAIRCMD) passing through a compressor 17 and a compressor front-rear pressure ratio P2/P1, and second opening determination of determining whether to open the air bypass valve 22 on the basis of an opening ratio reduction amount DRTHO as a reduction amount of an opening ratio RTHO of a throttle valve 13 are performed. The air bypass valve 22 is opened when it is determined in both of the first opening determination and the second opening determination that the air bypass valve 22 should be opened.

Abstract: A control device is provided capable of reliably preventing occurrence of a surging state by judging a possibility of the surging state in a relatively easy manner and promptly executing a surging state avoidance control. When a supercharging pressure decreasing state in which a target supercharging pressure decreases is detected, an operating speed of a wastegate valve is determined based on a detected engine rotational speed. That is, by lowering the operating speed as the engine rotational speed lowers, reduction in flow rate of the air passing through a compressor is prevented, and the occurrence of the surging state is reliably prevented. By lowering the operating speed instead of changing a target opening degree of the wastegate valve, a maximum opening degree of the wastegate valve can be suppressed, and responsiveness in the case where an acceleration request is made immediately after deceleration of an engine can be improved.

Abstract: An evaporated fuel treatment apparatus includes a diagnosis section for leak diagnosis of an evaporated fuel tightly-closed system. In first diagnosis stage in which an atmosphere on-off valve is in close state after an ignition switch is turned off, the diagnosis section performs first leak diagnosis, based on relationship between tank internal pressure detected by a tank internal pressure sensor and first threshold value; and in second diagnosis stage in which the atmosphere on-off valve is in close state after completion of first leak diagnosis, the diagnosis section performs second leak diagnosis, based on relationship between tank internal pressure detected by the tank internal pressure sensor and second threshold value. The atmosphere on-off valve is once opened after completion of first leak diagnosis. First threshold value is set with larger deviation from the atmospheric pressure compared with second threshold value used in second diagnosis stage.
