PURPOSE:To adjust fuel injection timing by displacing a sleeve in the rotary direction of a fuel cam in relation to the center of the fuel cam. CONSTITUTION:A sleeve 5 is inserted between a cam upper case 6 and a slide cylinder 3, and the inner diameter center 7 and the outer diameter center 8 are located eccentrically. A cam roller 2 drives a fuel injection pump plunger 4 through the slide cylinder 3, and the fuel is injected into the cylinder with a fuel injection valve. Since the centers of the inner and outer diameters are eccentrically located, the cam roller center is moved in the rotary direction of a fuel cam 1 by rotating the sleeve, thus resulting in a change of the fuel injection timing. |
