摘要
To offer a fuel supply system and fuel supply method for direct injection engine that realizes higher output. In a fuel supply system for direct injection engine of the present invention, equipped with a primary fuel injector that injects fuel directly into the cylinder of the direct injection engine and supercharger that increase the intake air quantity of the engine, a secondary fuel injector is installed in addition to the primary fuel injector. In a specified engine load area, fuel is supplied using the primary fuel injector and secondary fuel injector. Even though the fuel quantity injected from the primary fuel injector into the cylinder is limited, the fuel supply system for direct injection engine constructed as above can increase the engine output because the fuel insufficiency can be supplied by the secondary fuel injector.
