Abstract
A control device of a direct-injection engine is provided. The control device includes an engine body having a piston provided inside a cylinder and a combustion chamber formed by the cylinder and the piston, an injector for injecting fuel into the combustion chamber, an ozone generator for generating ozone inside the combustion chamber, and a controller for controlling the injector and the ozone generator. The controller controls the injector to inject a first amount of the fuel and, after this fuel is ignited, to inject a second amount of the fuel, and the controller controls the ozone generator to generate ozone in synchronization with the fuel injection that is performed by the injector after the fuel ignition.
