摘要： A compressor has a hub-side wall of a hub-side wall plate, a shroud-side wall that faces the hub-side wall and forms a diffuser path between the shroud-side wall and the hub-side wall, vanes that protrude from the hub-side wall plate into the diffuser path, and an actuator capable of changing the distance between the vanes and the shroud-side wall in accordance with a flow rate of air in the diffuser path. Adjacent ones of the adjacent vanes do not overlap with each other when viewed from a center axis of the compressor. When the actuator maximizes the distance between the vanes and the shroud-side wall, the distance between the vanes and the shroud-side wall is smaller than the distance between the hub-side wall and areas of the shroud-side wall that face the vanes.

摘要： A control apparatus is applied to an internal combustion engine. The internal combustion engine includes a turbocharger; an exhaust gas purifying catalyst which is arranged at a section downstream of a turbine in the exhaust passage; and a low pressure EGR passage which connects a section downstream of the exhaust gas purifying device in the exhaust passage and a section upstream of a compressor in the intake passage. The compressor is provided with a movable vane mechanism capable of varying throttled quantity of a flow passage of intake gas by moving diffuser vanes. The control apparatus controls the movable vane mechanism so that the throttled quantity of the flow passage is decreased when the exhaust gas is led to the compressor via the low pressure EGR passage as compared with a case when the exhaust gas is not led to the compressor.
