Abstract
In a control apparatus of an engine having a first fuel injection valve for injecting fuel into an intake path of the engine, a second fuel injection valve for injecting fuel into a combustion chamber of the engine, a supercharger for supercharging intake air for the engine, and a waste gate valve for opening and closing an exhaust bypass passage for bypassing a turbine of the supercharger, the waste gate valve is controlled to act in a closing direction in response to an increase in the injection amount of fuel injected from the first fuel injection valve, in a region where the injection amount of fuel from the first fuel injection valve is larger than the injection amount of fuel from the second fuel injection valve.
Claims8
A control apparatus of an engine having
- a first fuel injection valve for injecting fuel into an intake path of the engine,
- a second fuel injection valve for injecting fuel into a combustion chamber of the engine,
- a supercharger for supercharging intake air for the engine, and
- a waste gate valve for opening and closing an exhaust bypass passage for bypassing a turbine of the supercharger,
- the control apparatus comprising:
- fuel injection control device that controls injection amounts of fuel injected from the first fuel injection valve and the second fuel injection valve in accordance with an operating state of the engine;
- and
- valve control device that controls an opening/closing action of the waste gate valve,
- wherein the valve control device controls the waste gate valve to act in a closing direction in response to an increase in the injection amount from the first fuel injection valve, in a region where the injection amount from the first fuel injection valve is larger than the injection amount from the second fuel injection valve.
