摘要： A start lever (56) and a tension lever (18) are rotatable about a pin (19). The tension lever (18) is connected to a fuel control sleeve (28) so that an amount of fuel pumped and injected into an engine depends on the position of the tension lever (18) and sleeve (28). Upon rotation of flyweights (13), a governor rod (52) is urged through a hole (54) in the start lever (52) toward the tension lever (18) against the force of a start spring (22). A flange (53) formed on the governor rod (52) abuts against the start lever (18) so that the force of the start spring (22) is transmitted to the flyweights (13). The end of governor rod (52) abuts against the tension lever (18) at a certain engine speed so that further movement of the governor rod (52) is opposed by a governor spring (26) connected to the tension lever (18).
摘要翻译： 启动杆（56）和张力杆（18）可围绕销（19）旋转。 张紧杆（18）连接到燃料控制套筒（28），使得泵送和注入发动机的燃料量取决于张力杆（18）和套筒（28）的位置。 在飞轮（13）旋转时，调速杆（52）抵抗起动弹簧（22）的力被推动通过启动杆（52）中的孔（54）朝向张力杆（18）。 形成在调速杆（52）上的凸缘（53）抵靠启动杆（18），使得起动弹簧（22）的力传递到飞轮（13）。 调速杆（52）的端部以一定的发动机转速抵靠张力杆（18），从而调节杆（52）的进一步运动由与张力杆（18）连接的调速器弹簧（26）相对。

摘要： In a distribution type fuel injection system, the fuel injection advance angle, or the relative angular position at which fuel injection begins, is controlled by a first spring loaded piston (44). The spring force is opposed by pressurized fuel from a pump (14), the pressure increasing with engine speed. A second spring loaded piston (49) moves the first piston (44) to an advanced position for starting the engine and is retracted when the fuel pressure reaches a certain value to subsequently retard the advance angle in an idling speed range. The fuel pressure moves the first piston (44) to progressively advance the angle in a higher speed range. An electromagnetic valve (62) is controlled to trap fuel and apply a hydraulic lock to the second piston (49) during starting of the engine to prevent retarding of the advance angle until the engine speed or coolant temperature reaches a predetermined value.

摘要： In a distribution type fuel injection system, the injection advance angle, or the relative angular position at which fuel injection begins, is controlled by a first spring loaded piston (44). The spring force is opposed by pressurized fuel from a pump (14), the pressure increasing with engine speed. A second spring loaded piston (49) moves the first piston (44) to an advanced position for starting the engine and is retracted when the fuel pressure reaches a certain value to retard the advance angle in an idling speed range. The fuel pressure moves the first piston (44) to progressively advance the angle in a higher speed range. An O-ring (61) is provided to an end of the second piston (49) which abuts against an end wall (53) so that the fluid pressure receiving area of the second piston (49) is small when the second piston (49) abuts against the end wall (53) but is greater when the second piston (49) is moved away from the end wall (53). The effect is that the second piston (49) is prevented from moving and retarding the advance angle until the engine speed and fuel pressure reach a relatively high value upon starting of the engine. Thereafter, the advance angle will be retarded upon a return of the engine speed to the idling range.

Thus, improved starting characteristics of the engine can be obtained. Said relief channel may comprise a first channel communicating with the pump working chamber, and a second relief channel which has a portion thereof extending in the pump plunger to terminate in an outer periphery of the bottom end of said plunger and is so disposed as to communicate with the pump suction chamber after a predetermined delivery stroke length or prestroke has been executed. Communication between said first and second relief channels is adapted to be interrupted by said valve means at less than a predetermined engine r.p.m. As another advantagenous arrangement, the relief channel may comprise a first relief channel which consists of a port having one end communicating with the pump working chamber and the other end terminating in an outer periphery of the plunger and a communication channel having one end terminating in an inner periphery of the plunger barrel and the other end arranged for communication with a lower pressure zone, and a second relief channel allowing a restricted flow rate and communicating with the pump working chamber. The port and communication channel of said first relief channel are so disposed as to communicate with each other at the beginning of the delivery stroke of the plunger. Said first and second relief channels are arranged to be simultaneously blocked by said valve means during starting of the engine.
