Abstract
This control apparatus for an engine includes an engine, an injector, a spark plug, an intake electric S-VT, an exhaust electric S-VT, and a controller. The controller outputs a control signal to at least one of the intake electric S-VT and the exhaust electric S-VT so as to perform valve control of opening an intake valve when an exhaust valve is open, and then outputs a control signal to the spark plug at predetermined ignition timing such that, after air-fuel mixture is ignited and combustion is started, unburned air-fuel mixture is combusted by autoignition.
Claims11
A control apparatus for an engine, the control apparatus comprising:
- an engine having a 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;
- a variable valve mechanism configured to change valve timing of at least one of an intake valve and an exhaust valve;
- and
- a controller connected to each of the injector, the spark plug, and the variable valve mechanism, the controller configured to output control signals to the injector, the spark plug, and the variable valve mechanism, wherein
- the controller outputs a control signal to the variable valve mechanism so as to perform valve control of opening the intake valve when the exhaust valve is open, and then outputs a control signal to the spark plug at predetermined ignition timing such that, after air-fuel mixture is ignited and combustion is started, unburned air-fuel mixture is combusted by autoignition.
