Abstract
PURPOSE: To enable to facilitate the pilot injection and as well as obtain the optimum injection rate pattern for engine combustion by a method wherein a pressure reduction chamber to temporarily reduce the pressure of the fuel within a pressure feed pump chamber or an injection pump chamber of the fuel injection equipment.
CONSTITUTION: Now in running, when a pressure feed plunger 3 is pushed downward by a cam (not shown) and a metering lead 30 closes a metering port 10, the fuel within the pressure feed pump chamber 32 is pressure-fed so as to apply on an injection plunger 2. As a result, the fuel within the injection pump chamber 22 is led through passages 41, 43 and the like to a nozzle 44 and injected from nozzle holes by pushing up a needle valve with the fuel itself. After that, when the pilot lead 71 of a plunger 3 clears a pilot port 70, the highly pressurized fuel within the chamber 32 is released through vertical openings 34, 72 and the like into the pressure reduction chamber 6. Consequently, the injection plunger 2 stops and the pilot injection is ended. After that, the main injection is commenced by the continuous downward movement of the plunger 3.
