Abstract

One or more throttle bodies and a surge tank are disposed behind a cylinder head, and an intercooler is disposed by being adjacent to the surge tank at a position behind the cylinder head and the one or more throttle bodies. A supercharger is provided in front of the intercooler.

First claim

What is claimed is:

1. A motorcycle comprising:
a pair of left and right vehicle body frames extending in a front-and-rear direction;
an engine having one or more exhaust ports to which one or more exhaust pipes is/are connected at a front side of a cylinder head, and one or more intake ports to which one or more throttle bodies is/are connected at a rear side of the cylinder head;
a supercharger disposed at a front side of the engine, and compressing a sucked air for combustion;
an intercooler cooling the air compressed by the supercharger; and
a surge tank making the air from the intercooler flow to the one or more throttle bodies,
wherein the one or more throttle bodies and the surge tank are disposed behind the cylinder head, and the intercooler is disposed by being adjacent to the surge tank at a position behind the cylinder head and the one or more throttle bodies, positioned between the pair of left and right vehicle body frames in a view seen from an upper direction of the vehicle body, disposed inclined so that a front side thereof is lowered, and a wind-receiving surface is directed diagonally forward;
wherein the supercharger is provided in front of the intercooler.

2. The motorcycle according to claim 1 , wherein an inlet port and an outlet port of air are set on one side of the intercooler, and an internal air flow path of the intercooler has a shape of substantially U-shape.

3. The motorcycle according to claim 1 , wherein the intercooler is disposed below a seating seat, and at least a part of the intercooler is positioned behind a front end of the seating seat in a plan view of a vehicle body.

4. The motorcycle according to claim 1 , wherein the intercooler is disposed in a manner that a heat-radiating surface side thereof faces a space above a rear wheel.

5. The motorcycle according to claim 1 , wherein a part of the intercooler is overlapped with the surge tank in an up-and-down direction.

6. The motorcycle according to claim 1 , wherein the intercooler is disposed so that a longitudinal direction thereof extends in a front-and-rear direction of the vehicle body.

7. A motorcycle comprising:
an engine having one or more exhaust ports to which one or more exhaust pipes is/are connected at a front side of a cylinder head, and one or more intake ports to which one or more throttle bodies is/are connected at a rear side of the cylinder head;
a supercharger disposed at a front side of the engine, and compressing a sucked air for combustion;
an intercooler cooling the air compressed by the supercharger;
a surge tank making the air from the intercooler flow to the one or more throttle bodies; and
a bypass pipe whose one end is connected to an intermediate portion of a coupling pipe which connects the supercharger and the intercooler, and whose other end is connected to the surge tank or an intermediate portion of an outlet pipe which connects the intercooler and the surge tank,
wherein a control valve which controls an opening/closing of the bypass pipe is provided in the middle of the bypass pipe;
wherein the one or more throttle bodies and the surge tank are disposed behind the cylinder head, and the intercooler is disposed by being adjacent to the surge tank at a position behind the cylinder head and the one or more throttle bodies; and
wherein the supercharger is provided in front of the intercooler.

8. The motorcycle according to claim 7 , further comprising a second surge tank which is different from the surge tank connected to the one or more throttle bodies, wherein the second surge tank is provided on the coupling pipe.

9. The motorcycle according to claim 7 , further comprising an accumulating device operating to maintain a pressure of accumulated gas, wherein the accumulating device is provided on the coupling pipe.

10. The motorcycle according to claim 7 , further comprising a third surge tank directly connected to the surge tank.

11. The motorcycle according to claim 7 , further comprising a second accumulating device directly connected to the surge tank.

12. A motorcycle comprising:
an engine having one or more exhaust ports to which one or more exhaust pipes is/are connected at a front side of a cylinder head, and one or more intake ports to which one or more throttle bodies is/are connected at a rear side of the cylinder head;
a supercharger disposed at a front side of the engine, and compressing a sucked air for combustion;
an intercooler cooling the air compressed by the supercharger; and
a surge tank making the air from the intercooler flow to the one or more throttle bodies
a duct hose part leading a traveling air introduced from a front portion of the vehicle body to a heat-radiating surface of the intercooler to discharge the traveling air to a rear side of the vehicle body
wherein the one or more throttle bodies and the surge tank are disposed behind the cylinder head, and the intercooler is disposed by being adjacent to the surge tank at a position behind the cylinder head and the one or more throttle bodies;
wherein the supercharger is provided in front of the intercooler;
wherein the engine is supported by a pair of frames extended from a steering head pipe toward a rear side and a lower side of the vehicle body; and
wherein the duct hose part disposed substantially linearly from the front portion of the vehicle body to the intercooler by passing through a part between the pair of frames and a lower side of a fuel tank.

13. The motorcycle according to claim 12 , further comprising an inner fender covering a rear wheel from above, at a position between the rear wheel and a tail cowling, wherein the duct hose part has an introducing duct portion disposed substantially linearly from a front end of a front cowling to the intercooler, and a discharge duct potion disposed from the intercooler toward the rear side of the vehicle body, wherein the discharge duct portion discharges the traveling air after passing through the heat-radiating surface toward the inner fender.

14. The motorcycle according to claim 12 , wherein the duct hose part has an introducing duct portion disposed substantially linearly from a front end of a front cowling to the intercooler, and a discharge duct potion disposed from the intercooler to a rear end of a tail cowling, wherein an opening area of a discharge portion of the discharge duct portion is formed to be larger than an opening area of the discharge duct portion in proximity to the intercooler, and the discharge duct portion discharges the traveling air after passing through the heat-radiating surface toward the rear side of the vehicle body.

15. The motorcycle according to claim 13 , wherein a length on a side of a short side, out of lengths of sides along a discharge direction of the discharge duct portion, is greater than a thickness of the intercooler when seen from a side.

16. The motorcycle according to claim 1 , wherein the intercooler is disposed above a crankcase of the engine; and wherein the supercharger is disposed below the intercooler.

17. The motorcycle according to claim 16 further comprising an air cleaner which cleans taken air for combustion, wherein the air cleaner is disposed behind the supercharger and on a side lower portion of the crankcase.
