Abstract:
A fuel supply system for a direct injection engine comprising a fuel pump which supplies fuel to fuel injectors by varying the volume by the reciprocal movement of a single-cylinder plunger, a driving mechanism which makes one reciprocal movement of said plunger while two of said fuel injectors inject fuel into two cylinders, and a controller which controls said fuel pump to adjust the fuel supply pressure, the injection start timing, and the injection time width of said two fuel injectors, wherein said controller operates to make the injection time width of one of said two fuel injectors longer than an initially set injection time width for said one of said two fuel injectors and that of the other of said two fuel injectors shorter than an initially set injection time width for said other of said two fuel injectors.
