[0006] The intake control device assembly of Patent Document 1 is designed so as not to reduce the vehicle's storage space capacity by tilting the intake control device coupler downward.However, today, as the functionality required of vehicles increases, the space below the storage box is becoming extremely crowded, and there is a demand for an intake control device assembly that can achieve even greater layout freedom.

[0007] SUMMARY OF THE INVENTION In view of the above problems of the prior art, an object of the present invention is to improve the layout flexibility of the peripheral configuration of an intake control device assembly in a vehicle.

[0008] The intake control device assembly of the present invention is an intake control device assembly that is arranged in a space above an internal combustion engine and below a storage space in a vehicle, and that constitutes at least a part of an intake pipe continuing into the combustion chamber of the internal combustion engine, and includes: a body having a first intake passage therein that constitutes a part of the intake pipe; a valve body that is rotatably supported inside the first intake passage and adjusts the amount of intake air flowing into the first intake passage; a valve stem to which the valve body is fixed and rotatably supported on the body and has an end that protrudes outside the body; and a lever portion that is fixed to the end and receives an operating force to rotate the valve stem; and an inlet pipe that is connected to the body and has a second intake passage therein that constitutes a part of the intake pipe downstream of the first intake passage, and the lever portion obtains the operating force by the pulling force of a cable, and the cable is an inner cable of a Bowden cable, a fuel injection valve for injecting fuel into the second intake passage fixed to the inlet pipe by a fuel joint having an internal fuel passage connected to the fuel injection valve, the fuel joint having a connector portion for connecting the fuel passage to the outside, the connector portion being connected to a fuel hose constituting at least a part of the fuel passage connected to a fuel tank of the vehicle; an intake control device assembly in which the inlet pipe has a cable stay for fixing an outer cable of the Bowden cable downstream of the lever portion and upstream of the fuel injection valve, the cable stay and the lever portion being both arranged on one side divided by a center line extending from the center line of the first intake passage in a top view seen from a direction perpendicular to both the rotational center axis of the valve shaft and the intake passage direction which is the direction in which the first intake passage extends, and the connector portion being arranged on the other side divided by the center line or directly above the center line in the top view and protruding from the fuel joint towards the upstream side of the second intake passage,When the intake control device is viewed in a direction along the first intake passage, the space between the body and a body tangent that is parallel to the central axis of rotation and touches the edge of the body, and the space between the body and a lever tangent that is perpendicular to the central axis of rotation and touches the edge of the lever portion, is a hose space in which at least a portion of the fuel hose is arranged.

[0009] According to the present invention, a cable stay is provided in the inlet pipe section downstream of the lever portion and upstream of the fuel injection valve to form a hose space, and the cable stay and lever portion are arranged on one side of the center line of the first intake passage, and the connector portion protruding toward the upstream side is arranged on the other side or directly above the center line, so that the fuel hose can be easily passed through the hose space and the intake control device assembly can be formed compactly.

[0010] In this case, since the connector portion is positioned on the other side or directly above the center line, the distance between the connector portion and the hose space is maximized and the angle at which the fuel hose is bent can be made small, making it easier to position the fuel hose.

[0011] By mounting the compactly formed intake control device assembly in the space above the vehicle's internal combustion engine and below the storage space, the fuel hose can be placed in the small space between the intake control device assembly and the vehicle's storage space without compressing the storage space, thereby making it possible to increase the size of the storage space and improve the layout of the space around the intake control device assembly.

[0012] The vehicle of the present invention is characterized in that it comprises the above-mentioned intake control device assembly, and a fuel hose connected to the connector portion of the intake control device assembly is arranged in at least a portion of the hose space of the intake control device assembly.

[0013] This allows the fuel piping, including the fuel hose, to be compactly arranged in the small space between the intake control device assembly and the storage space, thereby making it possible to increase the size of the storage space and improve the layout of the space around the intake control device assembly.

[0015] An embodiment of the present invention will now be described with reference to the drawings. Figure 1 shows an intake control device assembly according to an embodiment of the present invention. This intake control device assembly 1 is disposed in a space above an internal combustion engine and below a storage space in a vehicle such as a scooter, and forms at least a part of an intake pipe leading to a combustion chamber of the internal combustion engine.

[0016] As shown in Figure 1, the intake control device assembly 1 comprises an intake control device 4 having a body 3 with a first intake passage 2 therein that forms part of the intake pipe, and an inlet pipe 6 connected to the body 3 and having a second intake passage 5 therein that forms part of the intake pipe downstream of the first intake passage 2.

[0017] Figure 2 shows the intake control device 4 as viewed in a direction along the central axis of the first intake passage 2. As shown in Figure 2, the intake control device 4 includes a valve element 7 that is rotatably supported inside the first intake passage 2 and that adjusts the amount of intake air flowing into the first intake passage 2, a valve shaft 8 that is rotatably supported on the body 3 to which the valve element 7 is fixed and has an end that protrudes outside the body 3, and a lever 9 that is fixed to the end and that receives an operating force that rotates the valve shaft 8.

[0018] 3 is a plan view seen from a direction perpendicular to both the rotational axis RA of the valve shaft 8 and the intake passage direction, which is the direction in which the first intake passage 2 extends. As shown in FIG. 3, the lever portion 9 obtains the operating force by the pulling force of a cable 10. The cable 10 is an inner cable of a Bowden cable 11.

[0019] A fuel injection valve 12 that injects fuel into the second intake passage 5 is fixed to the inlet pipe 6 by a fuel joint 13 that has a fuel passage therein that connects to the fuel injection valve 12. The fuel joint 13 has a connector portion 14 that connects the fuel passage to the outside. The connector portion 14 is connected to a fuel hose 15 that forms at least a part of the fuel passage that is connected to a fuel tank of the vehicle.

[0020] The inlet pipe 6 is provided with a cable stay 17 for fixing an outer cable 16 of the Bowden cable 11 downstream of the lever portion 9 in the intake pipe and upstream of the fuel injection valve 12 .

[0021] The cable stay 17 and the lever portion 9 are both located on one side of a line separated by a center line CL extending from the center line of the first intake passage 2, as viewed from above in a direction perpendicular to both the rotational center axis RA of the valve shaft 8 and the intake passage direction, which is the direction in which the first intake passage 2 extends, as shown in Figure 3.

[0022] In the top view, the connector portion 14 is disposed on the other side of the center line CL or directly above the center line CL, and protrudes from the fuel joint 13 toward the upstream side of the second intake passage 5 .

[0023] As shown in Figure 2, when the intake control device 4 is viewed in a direction along the first intake passage 2, the space between the body 3 and a body tangent line BL that is parallel to the rotation center axis RA and abuts the edge of the body 3, and the space between the body 3 and a lever tangent line LL that is perpendicular to the rotation center axis RA and abuts the edge of the lever portion 9, form a hose space HS in which at least a portion of the fuel hose 15 is arranged.

[0024] In this configuration, when connecting the fuel hose 15 to the fuel joint 13, one end of the fuel hose 15 is connected to the fuel joint 13, and the other end is connected to the vehicle's fuel tank or another pipe part that constitutes the fuel piping. This connection is made by passing the fuel hose 15 outside the body 3 toward the fuel tank, and the part of the fuel hose 15 that passes outside the body 3 is arranged to pass through the above-mentioned hose space HS.

[0025] At this time, the cable stay 17 of the Bowden cable 11 is located in the inlet pipe 6 portion downstream of the lever portion 9 and upstream of the fuel injection valve 12, and the connector portion 14 of the fuel joint 13 is located on the opposite side of the center line CL from the cable stay 17 or directly above the center line CL, so that the fuel hose 15 easily passes the center line CL side of the cable stay 17 and is arranged to pass through the hose space HS.

[0026] On the other hand, when the intake control device assembly 1 is disposed in the space above the internal combustion engine and below the storage space in a vehicle such as a scooter, the fuel hose 15 is passed through the hose space HS as described above to form a compact structure, and is disposed in a state that does not narrow the storage space more than before. This will be explained as follows using Figures 4 and 5.

[0027] That is, Figure 4 shows the relationship between the position of the fuel hose 15 in the intake control device 4 of this embodiment and the storage space 18. Figure 5 shows a similar relationship for a conventional case. As shown in Figure 4, the portion of the fuel hose 15 that passes outside the intake control device 4 is located within the hose space HS, so the lower end of the storage space 18 is relatively flat, and it can be seen that the storage space 18 is not narrowed by the fuel hose 15.

[0028] In contrast, in the conventional case shown in Figure 5, the cable stay 17 is attached to the intake control device, so the fuel hose 15 passes over the intake control device, which significantly reduces the storage space 18 due to the fuel hose 15.

[0029] As described above, according to this embodiment, the cable stay 17 is provided in the inlet pipe 6 portion to form the hose space HS, the cable stay 17 and the lever portion 9 are positioned on one side of the center line CL of the first intake passage 2, and the connector portion 14 protruding upstream is positioned on the other side or directly above the center line CL, so that the fuel hose 15 can easily pass through the hose space HS and the intake control device assembly 1 can be formed compactly.

[0030] In this case, the connector portion 14 is disposed on the other side or directly above the center line CL, so that the distance between the connector portion 14 and the hose space HS is maximized and the angle at which the fuel hose 15 is bent can be reduced, making it easier to arrange the fuel hose 15.

[0031] By mounting the intake control device assembly 1, which is formed compactly in this manner, in the space above the vehicle's internal combustion engine and below the storage space 18, the fuel hose 15 can be arranged in the small space between the intake control device assembly 1 and the vehicle's storage space 18 without compressing the storage space 18, thereby making it possible to increase the size of the storage space 18 and improving the layout of the space surrounding the intake control device assembly 1.

[0032] Although the embodiment of the present invention has been described above, the present invention is not limited to this. For example, the number of cables 10 that apply an operating force to the lever portion 9 is not limited to two, and may be one. In this case, the single cable 10 is used to apply an operating force in the valve-opening direction to the lever portion 9, and an operating force in the valve-closing direction may be applied by a spring.
