Abstract
A control apparatus for an engine includes an engine, a state quantity setting device, a spark plug, and a controller. After the spark plug ignites air-fuel mixture to start combustion, combustion of unburned air-fuel mixture is caused by autoignition. The controller outputs a control signal to the state quantity setting device such that, when a number of revolutions of the engine is high, a temperature in a combustion chamber before start of compression is higher than that when the number of revolutions of the engine is low.
Claims13
A control apparatus for an engine, the control apparatus comprising:
- an engine having a combustion chamber;
- a state quantity setting device mounted to the engine, the state quantity setting device configured to adjust introduction of fresh air and burned gas into the combustion chamber;
- an injector mounted to the engine, the injector configured to inject fuel;
- a spark plug disposed so as to face an inside of the combustion chamber;
- and
- a controller connected to the state quantity setting device, the injector, and the spark plug, the controller configured to output control signals to the state quantity setting device, the injector, and the spark plug, wherein
- after the spark plug ignites air-fuel mixture to start combustion, combustion of unburned air-fuel mixture is caused by autoignition, and
- the controller outputs a control signal to the state quantity setting device such that, when the number of revolutions of the engine is high, a temperature in the combustion chamber before start of compression is higher than that when the number of revolutions of the engine is low.
