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 distributor type fuel injection pump including a load-responsive pressure adjusting device which is responsive to engine loads for allowing drainage of part of the fuel in the suction chamber of the pump into a zone under lower pressure in the pump when the engine is operated within a predetermined load range, a pressure setting valve is provided in a drainage passage forming part of the pressure adjusting device, which is adapted to open at a predetermined pressure. The pressure setting valve enables establishment of necessary fuel pressure for normal actuation of a fuel injection timing control device provided in the pump within a low engine speed (rpm) range even during operation of the pressure adjusting device.

摘要： A fuel injection pump in which a relief channel is formed which communicates with the pump working chamber and is arranged to be blocked by a valve means, associated with a valve actuating means responsive to a pressure varying with engine r.p.m., during starting of the engine so that the fuel injection quantity is increased. 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 advantageous arrangement, the relief channel may comprise a first relief channel which includes 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.

摘要： A distributor type fuel injection pump which includes a port formed within the pressurized fuel distributing plunger with one end thereof communicating with the pump working chamber and the other end terminating in the outer periphery of said plunger, and a relief passage having one end thereof terminating in the inner peripheral wall of the plunger barrel and the other end communicating with a zone under a lower pressure. Said port and relief passage are so located as to register with each other at the beginning of the fuel delivery stroke of said plunger, and said relief passage is so arranged as to be permanently kept closed by a valve means which is actuated by a valve actuating means for actuating said valve means in response to a fuel supply pressure varying as a function of the engine rotational speed, except in a predetermined low engine speed range, to obtain a decreased injection rate during idling so as to increase the injection period, thereby reducing the rate of combustion of the engine to largely reduce the combustion noise.
