摘要： PROBLEM TO BE SOLVED: To reduce NOx from an engine.
SOLUTION: A jerk type fuel injection pump pressurizes fuel in a plunger chamber 6 to high pressure and feeds it to a fuel injection valve as an upper end reed 3 of a plunger 2 slidable for reciprocation in a plunger barrel 1 closes an oil inlet/outlet 5 and a lower end reed 4 opens the oil inlet/outlet 5. An outer circumference of the plunger 2 in a range from the upper end reed 3 for closing the oil inlet/outlet 5 to the lower end reed 4 has an initial pressure relief groove 20 for letting a trace quantity of fuel in the plunger chamber 6 out of the oil inlet/outlet 5 for a given period after the upper end reed 3 closes the oil inlet/outlet 5 to thereby form a shelf period with a gentle pressure rise gradient in a pressure rise process up to a maximal injection pressure.

摘要： PROBLEM TO BE SOLVED: To provide an engine, particularly a gas engine, which can be applied not only to a fuel injection valve of a relatively medium or small size but also to a fuel injection valve of a large size and which is enabled, by lowering the temperature near a nozzle seat portion, to prevent deposition and separation of carbides, thereby to perform the normal fuel injection control of a fuel injection system. SOLUTION: A fuel injection valve device comprises a nozzle equipped at its leading end with an injection hole for injecting fuel and a needle valve fitted reciprocally slidablly in the inner circumference, and a support body supporting the nozzle and having a cooling member housed therein for cooling the essential portion of the nozzle. The fuel injection valve device is characterized in that the distance A between a seat portion of the nozzle and the needle valve for controlling the ON/OFF of the fuel injection and the lowermost face of a nozzle inserting chamber of the support body is made smaller than the distance B between the lowermost face of the fitted portion of the nozzle fitted in a nozzle housing hole formed in the support body and the lowermost face, thereby to suppress a heat input amount to the seat portion.
