Description
SPECIFICATION
Fuel injection system
This invention relates to a fuel injection appa
ratus including a plurality of fuel injection
valves the nozzle ends of which project, in
use, into intake passages associated with the
cylinders of a multi-cylinder internal combustion engine and the intake ends of which are
connected to a common fuel supply unit.
In conventional fuel injections systems of this type, each fuel injection valve is individu
ally supported between the fuel supply unit
and the intake manifold. The fuel injection
valves are distinct units separate from both the fuel supply unit and intake manifold, thus
making the assembly or disassembly of the fuel injection system a troublesome operation.
Further, due to the fuel injection valves being distinct units, when the fuel supply unit is disconnected from the intake manifold the fuel injection valves do not remain in a completely mounted state with respect to the fuel supply unit, thereby making it difficult to conduct a pressure test of the fuel injection valves as mounted in the fuel supply unit.
This has led to great inconvenience for the automobile mechanic desiring to pressure test the system.
Viewed from one aspect the present invention provides fuel injection apparatus for a multi-cylinder internal combustion engine having an intake manifold adapted to receive a fuel injection valve for each cylinder, such apparatus comprising: a fuel supply unit having insertion apertures for receiving respective injection valves, a holding bracket for supporting said injection valves, an elastic sealing ring positioned in each said insertion aperture for sealing between a said injection valve and said fuel supply unit, said fuel injection valves being supported in place with respect to the fuel supply unit by means of said holding bracket, a vibration absorbing member supporting each fuel injection valve on said holding bracket, and means connecting said holding bracket to said fuel supply unit to enable that combination, with the said injection valves, to be mounted to an engine as a unit.
Viewed from another aspect the invention provides fuel injection apparatus for a multicylinder internal combustion engine having an intake manifold adapted to receive a fuel injection valve for each cylinder, such apparatus comprising: a fuel supply unit having apertures receiving the respective injection valves, a holding bracket having means for supporting each injection valve, and means connecting said mounting bracket to said fuel supply unit with the injection valves in position, whereby the apparatus may be mounted to an engine as a unit.
An embodiment of the invention will now be described by way of example and with reference to the accompanying drawings, in which:

Referring first to Figures 1 and 2, Figure 1 shows a fuel injection valve V, connected to a fuel supply unit 5 with the combined fuel injection valve and fuel supply unit mounted on an intake manifold Mi, the nozzle 36 of the valve being in communication with both the intake passage 3 of the manifold Mi and the engine intake port 2. Figure 2 shows the same arrangement when utilized on a fourcylinder engine, four fuel injection valves V1-V4 being connected to the fuel supply unit 5 and the entire assembly then being mounted on the intake manifold of the engine
E as shown in Figure 1.
An embodiment of the invention will now be described in more detail with reference to
Figures 4 to 9. A solenoid-operated fuel injection valve V3 is shown in Figures 4 and 7.
The valve V3 has a central body section Va, an upper intake section, and a lower nozzle section. The upper intake section of the valve consists of a short cylindrical section 19, a circular flange 20 and a larger diameter cylindrical section 39, as indicated in Figure 7.
The upper intake section of the fuel injection valve is mounted within the fuel supply unit 5 as shown in Figures 4 and 7, the upper end of the valve being inserted in an insertion aperture 1 7 which is connected to a first fuel passage 8 by way of a communication passage 18.
The fuel supply unit 5 is shown in detail in
Figure 2, and comprises an elongate body 6 having the first fuel passage 8 and a second fuel passage 9 formed therein. The first fuel passage 8 runs the length of the body 6, while the second fuel passage 9 terminates at an intermediate point thereon. The two passages are connected together by means of a fuel body cap 7 which is mounted on one end of the body 6 as shown in Figures 2 and 3, the cap 7 having a hollow centre section which allows fuel to flow from passage 8 to passage 9. A coupling joint 10 is affixed to the opposite end of the body 6 and connects the fuel supply unit 5 to a fuel source.Although not shown, a fuel pressure regulating valve is connected to the second fuel passage 9 at the aforementioned intermediate point, via an aperture 37, whereby the fuel pressure in passages 8 and 9 remains constant.
As shown in Figure 2 a plurality of fuel injection valves V1-V4, corresponding in number to the number of cylinders of the engine, are connected to the fuel supply unit 5 at mounting portions M1-M4 and are in communication with the first fuel passage 8 by means of the communication passages 18.
Each injection valve has a wiring connector portion 1 5 for electrically operating the valves.
Each fuel injection valve is held in place with respect to the fuel supply unit by means of a holding bracket 24 which is connected to the fuel supply unit 5, The holding bracket 24 has a support arm 38 which extends downward from the fuel supply unit 5 and a cylindrical holding member H3 which extends outward from the bottom of the support arm as shown in Figures 4 and 7. The fuel injection valve fits within the holding member H3 as shown. A circular radial flange 26 extends inward from the member H3 and abuts the body of the fuel injection valve. A vibration absorbing member 25 is fitted between the fuel injection valve and the holding member
H3 as shown in Figure 7 to lessen the amount of vibration transmitted from the engine E to the valve.
As shown in Figures 2 and 5 the holding bracket 24 is of an elongate configuration and is of approximately the same length as the fuel supply unit 5, having a plurality of holding members H1-H4 corresponding number to the insertion apertures 1 7. As shown in
Figures 2 and 5 the holding bracket 24 is mounted to the fuel supply unit 5 by means of connecting portions 27 extending from the bracket 24 and connected to the fuel supply unit by means of mounting bolts 28.
The aforementioned mounting portions M1-M4 are provided on the fuel supply unit for receiving the upper intake section of the fuel injection valve. Sealing means are provided at each mounting portion for sealably connecting the injection valve to the supply unit, and while an O-ring and sieeve may be employed, a specially designed seal ring 23 is preferred to prevent the leakage of fuel. This is shown in Figures 7 to 9. The elastic seal ring 23 comprises a cylindrical body portion 22, an upper inward flange portion 21 which projects radially inwards at one end of the body portion 22, and a lower flange portion 30 projecting radially inwards at the other end of the body portion.The upper inward flange 21 has a first annular sealing projection 31 projecting from its upper face, a second annular sealing projection 32 projecting from the outer peripheral face of the body 22, a third annular sealing projection 33 projecting from the lower outer corner portion of the upper flange 21, and a fourth annular sealing projection 34 projecting from the inner corner of the upper flange 21.
The intake section of the fuel injection valve is shown in Figure 9 set within the insertion aperture 1 7 in the fuel supply unit 5 without the elastic sealing ring 23 in place. The operation of the sealing ring 23 will now be discussed in conjunction with Figures 8 and 9. The natural axial thickness D, of the upper inward flange 21 is slightly larger than the length L1 of the cylindrical section 19 and the radial width D2 of the flange 21 is slightly smaller than the distance L2 between the cylindrical section 1 9 and the side face of the aperture 1 7. The relationship between D1, D2,
L, and L2 is such that the volume of the inward flange 21 occupies 82% to 114% of the volume of the space defined by the upper face 1 7a of the aperture 17, the side face of the aperture 17, the upper face of circular flange 20 and the outer face of cylinder section 19. In the preferred embodiment the volume of inward flange 21 is approximately 97% of the volume of the area just described.
Figure 7 shows the sealing ring 23 in place about the intake section of the fuel injection valve mounted within the fuel supply unit 5.
When inserting the fuel injection valve within the fuel supply unit, the elastic sealing ring 23 is first placed atop the valve such that the upper flange 21 of the sealing ring 23 rests atop the upper surface of the circular flange 20 and the lower flange 30 of the sealing ring extends inward beneath the circular flange 20, with the upper surface of flange 30 being in contact with the lower surface of circular flange 20. The fuel injection valve within the elastic sealing ring 23 now in place is then inserted within the insertion aperture 1 7 until the upper face 35 of the cylindrical section 19 abuts the upper face of aperture 1 7. In this position the upper flange 21 is radially compressed such that the annular sealing projections 31, 32, 33, 34 are each compressed into close contact with the surfaces opposite them. In this position fuel is prevented from flowing along the upper face of flange 21 by means of the first annular sealing projection 31 and is prevented from flowing along the bottom face of flange 21 by means of the third annular sealing projection 33. In the event that either sealing projection 31 or 33 is inadequate.to stop the flow of fuel, they are backed up by annular sealing projections 32 and 34 respectively. In addition to providing for sealing of the mounting of the fuel injec tion valve, the elastic seal ring 23 also acts as a restriction against lateral movement of the valve within the insertion aperture 1 7 and thereby keeps the cylinder 1 9 aligned with passage 18.
To check against the inadvertent omission of the elastic sealing ring 23 during the mounting procedure the cylindrical section 1 9 is equipped with a channal 40 cut in its upper face 35 as shown in Figure 10. Should the elastic sealing ring 23 be accidentally omitted, fuel will readily flow through the channel 40 and out of the insertion aperture 1 7 and be easily detected.
Once each of the fuel injection valves has been mounted within the fuel supply unit 5 and pecurely fastened to the supply unit by means of the holding bracket 24, the entire assembly as shown in Figure 2 is then mounted on the engine. The nozzle ends 36 of the fuel injection valves are fitted with a circular sealing member 4 and inserted within apertures 16 in the upper surfaces of the intake manifold Mi. The assembly is then bolted to the intake manifold by means of mounting bolts 1 3 which are inserted through apertures in support arms 11 extending outward from the fuel supply unit 5 and are screwed into corresponding mounting apertures in a support base 12 formed integrally with the intake manifold. An insulating material 14 may be interposed between the manifold and fuel supply unit, as shown in
Figure 1.
When finally mounted, the nozzle end 36 of each of the fuel injection valves is in communication with both the intake passage 3 of the intake manifold Mi and the intake port 2 of the engine E.
It will be noted that in the above described embodiment of the present invention apertures 1 7 are formed in a side portion of a fuel supply unit having a central fuel passage 8, so as to intersect said fuel passage, and the fuel injection valves V,V4 are connected to the fuel supply unit 5 by means of the holding bracket 24 affixed to said fuel supply unit such that the intake ends of the fuel injection valves fit within the apertures 1 7 formed in the side portion of the fuel supply unit. In prior mounting structures of this sort, nipple portions were provided on the side of the fuel supply unit and the intake ends of the fuel injection valves were inserted into the nipple portions after attaching an O-ring and a seal ring to each of the intake ends.In such prior mounting structures, however, it was necessary that the fuel injection valve and the nipple portion be exactly aligned with each other when inserting the former into the latter in order to prevent the O-ring or the seal ring from being twisted or broken. Thus, prior mounting operations required considerable skill and were quite troublesome. Further, with the prior systems the mere insertion of the intake end of the fuel injection valve into the nipple portion did not prevent the fuel injection valve from becoming separated from the nipple portion, thereby rendering it necessary to secure the fuel injection valve by loading or compressing the O-ring and the seal ring by means of a spring or other biasing means.Further, in such prior mounting structures it was necessary to provide at least two members, one being a seal ring for restricting lateral movement of the fuel injection valve and the other being an O-ring for preventing fuel leakage.
It will thus be seen that this invention, at least in its preferred embodiment, provides fuel injection apparatus in which a fuel supply unit and a plurality of fuel injection valves constitute an integral unit, thereby facilitating the assembly and disassembly of the fuel injection apparatus and further allowing for the conducting of a pressure test when the fuel supply unit is disconnected from the intake manifold. Furthermore there is provided fuel injection apparatus which facilitates the mounting operation by the use of a single elastic seal ring which functions both as a sealing member and as a lateral movement restriction member with respect to the fuel injection nozzles.
