    摘要: The high pressure fuel injection system utilizes a pressure regulating or control valve (28) in an injector leak-off fuel conduit (26) to provide a high residual pressure within the injector (5) between injections. Maintaining a high residual fuel pressure boosts the injection pressure to provide improved fuel atomization, with consequent reductions in particulate emissions and increased fuel efficiency. The pressure regulating valve (28) may be controlled in accordance with engine operating conditions to provide a variable injection pressure boost commensurate with engine requirements.

    摘要: Accumulator injector comprising a needle valve (30), an accumulator chamber and an amplifier chamber (64) in communication with the source of pressurized fuel, the end (74) of the valve (30) being subjected to the pressure in the amplifier chamber (64). An amplifier piston (70') is provided for boosting the pressure in in the amplifier chamber (64) and in the accumulator chamber. A duct (80') extends from a valve assembly (82) along side of and spaced from the amplifier cylinder (72) and communicates with the cylinder (72) by means of a smaller lower port (106) and a larger upper port (108). By restricting the rate of movement of the amplifier piston (70') upwardly, the pressure in the amplifier chamber (64) and hence in the accumulator chamber is relieved at a slower rate, hence changing the rate of opening of the needle valve (30) and the rate of fuel injection. The initial fuel flow from the end chamber (116) through the small port (106) produces a pilot injection. The injection rate is controlled by restricting the pressure decay in the amplifier chamber (64).

    摘要: The high pressure fuel injection system utilizes a pressure regulating or control valve (28'') to provide a high residual pressure within the injector (5'') between injections. Maintaining a high residual fuel pressure boosts the injection pressure to provide improved fuel atomization, with consequent reductions in particulate emissions and increased fuel efficiency. The pressure regulating valve (28'') located in the high pressure line (6) connecting the fuel injection pump (90) with the injector (5''), may be controlled in accordance with engine operating conditions to provide a variable injection pressure boost commensurate with engine requirements.

    摘要: A fuel injection pump of the rotary distributor type having opposed fuel pumping pistons (1121 housed within a rotor (94) and actuated by an internal ring cam (128). Fuel distribution, metering and timing control are effected through ports and slots associated with the rotor (94), the pump (hydraulic head (80) and a spill sleeve (176). The angular position of the cam (128) is varied automatically in accordance with changes in engine speed as are the relative positions of certain ones of said ports and slots to provide an automatic advance of the fuel injection timing. The pump is particularly suited for electronic governing, electronic timing control and electronic control of rate of injection.
