Abstract: The present invention adds a separate pilot pumping chamber and associated pumping plungers and cam followers axially offset from the main pumping chamber and pumping plungers. The axis of the pilot plunger bores is angularly offset from the axis of the main plunger bores so that the pilot plungers are actuated by a different set of cam lobes of the cam profile. This arrangement allows one pumping chamber to be refilled while the other pumping chamber is being discharged. A pilot injection event well in advance of the main injection can take place without refilling problems because each pumping chamber fills once for an injection event that includes a pilot and main injections. Discharge passages from the respective pumping chambers are ported to deliver the pilot and main fuel pulses to the same discharge port.

Abstract translation: 本发明增加了一个单独的先导泵送室和相关联的泵送柱塞和凸轮从动件从主泵室和抽吸柱塞轴向偏移。 先导柱塞孔的轴线与主柱塞孔的轴线成角度地偏移，使得导向柱塞由凸轮轮廓的不同组的凸轮凸角致动。 这种布置允许在另一个泵送室被排放时重新填充一个泵送室。 可以在主喷射之前很好地进行先导喷射事件，而不会重新填充问题，因为每个泵送室填充一次用于包括飞行员和主喷射的喷射事件。 输送来自相应泵送室的排放通道以将先导和主燃料脉冲输送到相同的排出口。

Abstract: A rotor that rotates in synchronization with an engine is provided inside a housing and a cam ring is provided outside and around the rotor so that plungers are caused to move reciprocally in the direction of the radius by the cam ring as the rotor rotates. At both sides of the cam ring, support members (barrel 8, bearing support member 6) constituted of the same material as that of the cam ring are secured to the housing and to both sides of the cam ring, and these support members alone hold the cam ring from both sides rotatably. A connecting rod connecting the cam ring and the timer mechanism is formed as an integrated part of the cam ring. The clearance between the cam ring and the members holding it can be set small so that the vibration of the cam ring is reduced to minimize the impact noise made by the cam ring and wear of the cam ring. In addition, the connection strength between the cam ring and timer mechanism is increased.

Abstract: In an inner cam type injection pump, the side surface of the protruding portion of each of the plungers facing the compression space is formed in a projecting shape in the area where the plunger changes from the base end side into the front end. Specific forms of the projection include a structure constituted with slanted surfaces over a plurality of stages with different inclinations relative to the axis of the plunger, an arc form and a structure provided with a overhanging portion formed on the side surface of the protruding portion, which does not overhang the base end, projecting out from the side surface. This will prevent collision at the shoulder portion of the plunger and, consequently, prevent the deformation at the shoulder portion and ensures that plungers will not have sliding failures or become seized. Even when plungers collide, the sliding of the plungers will not be affected, ensuring that plungers do not have sliding failures or become seized.

Abstract: A fuel supply apparatus for supplying fuel to a compression ignition engine comprising a rotary distributor member having a delivery passage which can register in turn with outlet ports connected to the injection nozzles of the engine. Fuel is supplied to the delivery passage from an accumulator under the control of a valve. The accumulator is charged with fuel by means of a high pressure pump which is a cam actuated pump and fuel is supplied to the high pressure pump by a low pressure pump. A valve is provided to control the output pressure of the low pressure pump so that the amount of fuel supplied to the high pressure pump can be varied for the purpose of controlling the fuel pressure within the accumulator. This pressure is sensed by a transducer which supplies a signal to a control system which controls the flow of electric current in the valve.

Abstract: A fuel injection pump of the rotary distributor type includes a pumping element movable in a bore to displace fuel from the bore to the injection nozzles of an engine in turn. A regulator controls the supply of fuel to the bore and is responsive to the speed of the engine and the setting of a control lever coupled to the accelerator pedal of a vehicle driven by the engine. The pump also includes valve means which is opened when the engine speed is above a predetermined value and the accelerator pedal has been released by the vehicle driver. The valve means when open prevents the supply of fuel to the engine and as the engine speed falls closes at a predetermined speed to restore the supply of fuel.

Abstract: A first plunger pump serves to inject fuel into the combustion chamber of an internal combustion engine during first periodical compression strokes as the crankshaft of the engine rotates. A second plunger pump serves to inject fuel into the combustion chamber during second periodical compression strokes as the crankshaft rotates. The maximum fuel injection quantity during each second compression stroke of the second plunger pump is smaller than that during each first compression stroke of the first plunger pump. A sensor detects load on the engine. A mechanism serves to advance the timing of the first compression strokes relative to that of the second compression strokes with respect to the rotational angle of the crankshaft as the detected engine load increases. The characteristic curve of the rate of the sum of the fuel injections effected by the first and second plunger pumps with respect to the rotational angle of the crankshaft can vary in accordance with the engine load.

Abstract: The fuel injection method uses a distributor-type fuel injector pump for an internal combustion engine which has a rotary distributor member formed with two outlet passages communicating with a pump chamber and arranged to distribute fuel intermittently to successive fuel delivery apertures leading to respective engine cylinders, so that in each revolution of the distributor the pump delivers to each cylinder a principal fuel injection at the end of the compression stroke, preceded by a pre-injection. Automatic timing control means advance the delivery stroke of the pump automatically in response to engine speed increase, and the angle between the outlets of the two outlet passages is such that as the engine speed varies the ratio of the fuel pre-injected to that of the principal injection into each cylinder varies according to a rule predetermined in relation to the type of engine (i.e. precombustion chamber or direct injection type).
