Abstract

In an intake device, an upper fuel injection device that injects a fuel and a suction port that suctions the air-fuel mixture supplied to a cylinder head are disposed in the air cleaner. The intake device includes the air cleaner including an air cleaner case and a sidewall filter that purifies an air suctioned into the air cleaner case. The sidewall filter partitions a space in the air cleaner case in a vehicle width direction, and has at least partially overlapping with the upper fuel injection device in the vehicle width direction.

First claim

The invention claimed is:

1. An intake device for a saddle riding vehicle comprising:

wherein each of the right and left filters partitions a space in the air cleaner case in a vehicle width direction, and is at least partially overlapping with the fuel injection device in the vehicle width direction; and,
wherein the air cleaner case has an upper wall on which a recess is disposed at an inner side in the vehicle width direction with respect to the right and left filters.

2. The intake device for the saddle riding vehicle according to claim 1 ,
wherein the right and left filters disposed in a range equal to or more than a length of the fuel injection device in a vehicle front-rear direction.

3. The intake device for the saddle riding vehicle according to claim 2 ,
wherein right and left filters are is disposed in a range equal to or more than a distance from the suction port to an injection hole of the fuel injection device in the vehicle front-rear direction.

4. The intake device for the saddle riding vehicle according to claim 2 ,
wherein each of right and left filters is inclinedly disposed such that an upper end is located at an inner side in the vehicle width direction with respect to a lower end.

5. The intake device for the saddle riding vehicle according to claim 2 ,
wherein a duct is coupled to the air cleaner case and guides air into the air cleaner, and the right and left filters are is disposed to face a suction port of the air cleaner case to which the duct is coupled.

6. The intake device for the saddle riding vehicle according to claim 1 ,
wherein the right and left filters are disposed in a range equal to or more than a distance from the suction port to an injection hole of the fuel injection device in the vehicle front-rear direction.

7. The intake device for the saddle riding vehicle according to claim 6 ,
wherein each of right and left filters is inclinedly disposed such that an upper end is located at an inner side in the vehicle width direction with respect to a lower end.

8. The intake device for the saddle riding vehicle according to claim 6 ,
wherein a duct is coupled to the air cleaner case and guides air into the air cleaner, and the right and left filters are disposed to face a suction port of the air cleaner case to which the duct is coupled.

9. The intake device for the saddle riding vehicle according to claim 1 ,
wherein each of the right and left filters is inclinedly disposed such that an upper end is located at an inner side in the vehicle width direction with respect to a lower end.

10. The intake device for the saddle riding vehicle according to claim 9 ,
wherein a duct is coupled to the air cleaner case and guides air into the air cleaner, and the right and left filters are is disposed to face a suction port of the air cleaner case to which the duct is coupled.

11. The intake device for the saddle riding vehicle according to claim 1 ,
wherein a duct is coupled to the air cleaner case and guides air into the air cleaner, and the right and left filters are disposed to face a suction port of the air cleaner case to which the duct is coupled.

12. The intake device for the saddle riding vehicle according to claim 11 ,
wherein the suction port of the air cleaner case, the right and left filters, and the fuel injection device are at least partially overlapping in the vehicle width direction.

13. The intake device for the saddle riding vehicle according to claim 1 ,
wherein the right and left filters are held by a filter holding member that has a filter side recess formed into a shape that runs along the recess of the air cleaner case.

14. The intake device for the saddle riding vehicle according to claim 1 ,
wherein each of the right and left filters comprises a front side filter and a rear side filter, said rear side filter being arranged at a rear of the front side filter, wherein the suction port of the air cleaner case, the front side filter, and the fuel injection device overlap in side view,
the right and left filters are held by a filter holding member that includes a front wall, a rear wall and an upper wall, a part of a peripheral wall of the filter holding member has openings, the peripheral wall comprising the front wall, the rear wall and the upper wall, and
the right and left filters are disposed on the openings.

15. The intake device for the saddle riding vehicle according to claim 14 ,
wherein the filter holding member includes a right sidewall and a left sidewall.

16. The intake device for the saddle riding vehicle according to claim 15 ,
wherein a duct is coupled to the air cleaner case and guides air into the air cleaner,
