Abstract
A gasoline direct-injection engine is provided. The engine causes a self-ignition of a fuel injected into a cylinder by an injector and at least containing gasoline. The engine includes a controller for controlling the fuel injection by the injector. A geometric compression ratio of the engine is 15:1 or higher. The controller causes the injector to perform a pre-injection for keeping a variation of an in-cylinder temperature after a compression top dead center within a predetermined temperature range by injecting an amount of the fuel that causes an oxidative reaction without resulting in a hot flame reaction. The controller causes the injector to perform a main injection for causing self-ignition combustion of the fuel after the compression top dead center while the variation of the in-cylinder temperature is kept within the predetermined temperature range, by injecting the fuel after the pre-injection.
