<p><P>PROBLEM TO BE SOLVED: To reduce variation of torque in re-acceleration from a deceleration state. <P>SOLUTION: A control device is provided with: a supercharger 5 driven by exhaust gas energy of an internal combustion engine; a variable valve train 14, an intake air quantity adjusting means 4; a pressure detection means 11 detecting supercharged pressure which is pressure in an intake air passage 6a at a downstream of a compressor 5a and at an upstream of the intake air quantity adjusting means 4; a recirculation passage 10 providing communication between the intake air passage 6a at the downstream of the compressor 5a and at the upstream of the intake air quantity adjusting means 4 and an intake air passage 6b at an upstream of the compressor 5a; an open close valve 9 opening when differential pressure of supercharging pressure and intake air pipe pressure which is pressure in the intake air passage 2 exceeds a prescribed value; and a deceleration state detection means 13 detecting deceleration state based on accelerator pedal operation quantity. The device executes deceleration control for changing open close timing of an intake valve according to supercharging pressure so as to keep the differential pressure of the supercharging pressure and the intake air pipe pressure, constant during deceleration under a condition where the recirculation valve 9 is opened. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
