  • Publication number: 20130068193
    Abstract: The present invention relates to a dual fuel injection valve apparatus provided with a hybrid nozzle for a diesel engine and a gas engine and an objective thereof is to provide a dual fuel injection valve apparatus provided with a hybrid nozzle for a diesel engine and a gas engine, being capable of respectively injecting two kinds of different fuels from one fuel injection valve by pressure of fuel and tension of a spring. In a fuel injection valve apparatus for injecting fuel to a cylinder of a diesel engine or a gas engine, the present invention sequentially injects, without mixing, two kinds of fuel through respective nozzle holes by pressure of the two kinds of fuel introduced to a fuel valve and tension of a needle spring.

  • Publication number: 20130037004
    Abstract: The present invention provides a two solenoid valve relay with a two-phase fuel injection valve for a diesel engine, which is installed on a valve itself to enable injection at pressure greater than opening pressure, at which the fuel enters into a fuel valve, thereby improving fuel injection performance, and which is configured to enable adjustment of an injection timing at the opening pressure within the valve, wherein injection timings through a solenoid valve is provided for low load and high load, respectively, such that a distinct difference exists between the injection timings to open the nozzle hole of the nozzle in a differential manner at pressure higher than the pressure, at which the fuel enters to the fuel valve and internal spring opening pressure, thereby injecting fuel at high pressure even at low load to facilitate vaporization, and wherein, in case of a high speed operation or high load, low pressure/high pressure needle valves are opened at the same time to quickly inject fuel of a high vol

  • Publication number: 20130015274
    Abstract: The injection system of a fuel injection pump is provided. In the injection system of a fuel injection pump, a plunger performs a reciprocating slide motion in the axial direction inside of the plunger chamber of a barrel for compressing fuel. The plunger has a release groove and a control edge. A spill port is formed in the wall surface of the barrel. A damping groove is formed in the upper-part outer circumference of the control edge and provides a fine fuel flow path. The damping groove meets the spill port in advance to form the fine flow of fuel from the plunger chamber to the spill port before the control edge of the plunger meets the spill port to release pressure.

  • Publication number: 20120325937
    Abstract: Disclosed herein is a two-stage fuel injection valve for a diesel engine. The valve includes a fuel valve block (110) having therein a passage (1701) into which fuel is supplied; a nozzle (140) having a low pressure nozzle hole (160) and a high pressure nozzle hole (161); a needle valve (130) differentially opening the low pressure nozzle hole and the high pressure nozzle; pressure booster spindles (141), (142) and (143) pressurizing the needle valve to boost pressure of low-load fuel; a shuttle valve (150) configured to supply a gauge pressure to the pressure booster spindles, thus raising the pressure of the fuel; a lifting bush valve (180) discharging fuel to a fuel discharge hole through a gap between the fuel discharge hole and a nozzle holder when a solenoid valve (201) is moved upwards; and the solenoid valve (201) controlling pressure applied to the lifting bush valve.

  • Publication number: 20110259302
    Abstract: The present invention relates to an apparatus for preventing cavitation damage to a diesel engine fuel injection pump, wherein a pressure control valve for shutting a barrel port is mounted on a deflector or a barrel of the fuel injection pump to increase the fuel pressure in the barrel port during an early stage of fuel compression. This prevents fountain-type or jet-type cavitation from occurring before and after the opening of the barrel port during a late stage of fuel compression, thereby preventing corrosion damage caused by cavitation occurring mainly in a plunger and the barrel port of the fuel injection pump.
