Abstract
A fuel injection system which can effectively control a residual pressure in an injection pump so as to reduce soot and hydrocarbons in an exhaust gas when an engine is operating at a low speed. The fuel injection system features a structure in which a passage is formed in a plunger barrel, extends between a delivery valve chamber and a pressurization source, and is in communication with these chambers via a plunger when it is in contact with a base circle of a cam.
