摘要： A distribution type fuel injection pump for use in a fuel injection combustion engine comprising a plunger capable of moving reciprocally along its axis and simultaneously rotating about its axis and a couple of members forming a cam mechanism having a first cam member and a second cam member. The first cam member is mounted on the plunger and the second cam member is mounted on a housing rotatably about its axis. The couple of cam members cause the plunger to reciprocally move while the plunger is rotating. The angular position of the second cam member about its axis can be controlled by a fuel injection timing control means in accordance with the engine speed. The second cam member can also turn about its axis so as to be adjusted in its angular position by a fuel injection timing adjustment when a selected operating condition of the engine, for example the engine start, is carried out.

摘要： A fuel supply pump supplies fuel from a fuel reservoir to a fuel injection pump which comprises a piston for injecting fuel from a fuel injection nozzle into an internal combustion engine. The piston is reciprocated for fuel injection by an engine driven rotary cam. The fuel injection pump further comprises a fuel control sleeve which is positioned by flyweights to control the fuel injection volume in accordance with the engine speed. A modulator valve is actuated by the flyweights to control the supply pump pressure in accordance with engine speed. A fuel injection timing means is responsive to the modulated supply pump pressure to control the angular relationship between the engine crankshaft and the rotary cam and thereby the fuel injection timing in accordance with the modulated pressure.

摘要： A control system for a fuel injection pump assembly wherein the regulation of the fuel quantity is influenced by a control rod. This control rod is displaced by a cam follower assembly and the cam itself is a three-dimensional cam whose spatial orientation may be changed, firstly, by rotation about its axis where the magnitude of this rotation depends on the amount of air aspirated by the engine and, secondly, by longitudinal motion along its axis, where the magnitude of this motion depends on the rotational speed of the engine.

摘要： A pintle on the tip of the nozzle needle, which is disposed to be fitted through the nozzle hole of the nozzle body opening in a combustion chamber of an engine, has a conical portion. The conical portion extends along substantially the whole length of the nozzle hole when the nozzle needle has its seating portion seated on a valve seating portion of the nozzle body, and has a depth gradually decreasing toward the combustion chamber to define between itself and the nozzle needle an annular gap gradually expanding toward the combustion chamber. A portion of the pintle, which is substantially on a level with an end of the nozzle hole remote from the combustion chamber when the seating portion of the nozzle needle is in its seated position, has a diameter substantially equal to the inner diameter of the above end of the nozzle hole.

摘要： A servo piston is driven to compress fuel in a pressure chamber which communicates with a needle valve which is spring biased to block communication between the pressure chamber and a fuel injection nozzle. When the fuel pressure exceeds a value equivalent to the preload of the spring, the pressurized fuel moves the needle valve off its seat so that fuel from the pressure chamber is injected into an engine through the injection nozzle. Further movement of the servo piston unblocks a port to allow fuel at supply pressure to act on the needle valve in the same direction as the spring to sharply seat the needle valve and cleanly terminate fuel injection. Further movement of the servo piston uncovers another port so that the pressure chamber is depressurized through connection with the supply and the needle valve is firmly held on its seat.
摘要翻译：伺服活塞被驱动以在与针阀连通的压力室中压缩燃料，所述针阀被弹簧偏置以阻止压力室和燃料喷射喷嘴之间的连通。当燃料压力超过与弹簧的预压相当的值时，加压燃料将针阀从其阀座移开，使得来自压力室的燃料通过喷嘴喷射到发动机中。伺服活塞的进一步运动解除了一个端口，允许供应压力下的燃料在与弹簧相同的方向上作用在针阀上，以锐利地安置针阀，并且清洁地终止燃油喷射。伺服活塞的进一步运动揭开另一个端口，使得压力室通过与电源的连接而减压，并且针阀牢固地保持在其座上。
