CONTROL APPARATUS FOR AN INTERNAL COMBUSTION ENGINE WITH SUPERCHARGER AND METHOD FOR CONTROLLING THE SUPERCHARGING PRESSURE |
摘要 |
A control apparatus for an internal combustion engine with a supercharger capable of adjusting the supercharging pressure to a target pressure. The control apparatus includes a supercharging pressure control unit adjusting the supercharging pressure to the target pressure by changing the opening degrees of exhaust flow rate regulating valves based on the physical model of the engine with a turbocharger, a supercharging pressure state determination unit determining whether the actual supercharging pressure is equal to or more than the target pressure with the exhaust flow rate regulating valves put in the fully closing state, and a valve opening release unit changing the opening degrees of the exhaust flow rate regulating valves in the opening direction from the fully closing state when the actual supercharging pressure is equal to or more than the target pressure with the exhaust flow rate regulating valves put in the fully closing state. |
