摘要： A pressure accumulation system for an internal combustion engine can prevent exhaust pressure from excessively increasing when pressurized gas is contained in a pressure accumulation container. A pressure accumulation system is applied for an internal combustion engine provided with an exhaust shut-off valve mounted in an exhaust path. The pressure accumulation system has a pressure accumulation tank into which gas can be introduced from that portion of an exhaust path. The pressure accumulation system also has a sensor for detecting the exhaust pressure, and an EGR valve is controlled based on the detection value from the exhaust gas sensor such that the pressure in that portion of the exhaust path which is on the upstream of the exhaust shut-off valve is limited below a predetermined exhaust gas upper limit value (Pmax) when gas is contained in the pressure accumulation tank.

摘要： In an internal combustion engine provided with a rotary intake control valve, preferable position convergence at the end of inertia supercharging is ensured while avoiding an influence on combustion performance. In an engine provided with an impulse valve, if the implementation of the inertia supercharging is stopped and a request to maintain the impulse valve at a fully-opened position is made, an ECU stops the supply of a braking force to the impulse valve until the rotational phase of the impulse valve enters dead band, and the ECU performs a BRK mode for stopping the impulse valve under the condition that the rotational phase enters the dead band and that the impulse valve is in a deceleration state. At this time, electrification or power distribution for acceleration of the impulse valve during stop control of the impulse valve is forbidden. Moreover, the converging position of the impulse valve by the BRK mode is allowed to deviate in a range with an allowable width set in advance with respect to a target.
