FUEL JETTING DEVICE OF RECIPROCATING PISTON COMBUSTION ENGINE

摘要

PURPOSE: A fuel jetting device of a reciprocating piston combustion engine is provided to excite individually an injecting nozzle. CONSTITUTION: The fuel jetting device comprises:a metering piston(1) measuring the fuel amount for injecting; a control device(2) controlling a metering piston; a controlling member supplying fuel to a fuel nozzle(5); and a fuel supplier(14) having a hydraulic-electric device(4) that controls the injection. Then, the metering piston increases fuel by injecting pressure as designing with a pressure amplifier(1) and the controlling member is placed in the rear of the pressure amplifier in fuel flowing direction as designing with a control valve(3). Also the control device and the control valve control the injection by connecting with the hydraulic-electric device.
