Japanese Unexamined Patent Publication No. 2012-1119

In a conventional saddle-mounted vehicle, the purge valve is arranged side by side with the canister in the vehicle width direction, so the hose connecting the purge valve and the throttle body becomes long, and the hose connecting the purge valve and the throttle body is efficiently arranged. Difficult to do.

An object of the present invention is to provide a Norikura-type vehicle capable of efficiently arranging a hose connecting a purge valve and a throttle body.

The saddle-mounted vehicle according to one aspect of the present invention includes a vehicle body frame, an engine, a fuel tank, a canister, a purge valve, and a hose. The body frame includes the head pipe. The engine includes the throttle body. The engine is supported by the body frame. The fuel tank is located behind the head pipe. The canister is located behind the throttle body and below the fuel tank. The purge valve is arranged above the canister, overlaps the throttle body in the front-rear direction of the vehicle when viewed from the side of the vehicle, and is connected to the canister and the throttle body. The hose connects the throttle body and the purge valve.

In the saddle-mounted vehicle according to this embodiment, the canister is arranged behind the throttle body, the purge valve is arranged above the canister, and the purge valve overlaps the throttle body in the front-rear direction of the vehicle when viewed from the side of the vehicle. Therefore, since the purge valve can be arranged at a position close to the throttle body, the hose connecting the throttle body and the purge valve can be shortened. As a result, the hose connecting the throttle body and the purge valve can be efficiently arranged. Further, since the canister is arranged below the fuel tank, the hose connecting the canister and the fuel tank can be shortened.

The canister and purge valve may be located inside the vehicle body frame. In this case, it is possible to prevent the canister from being directly impacted when the vehicle falls.

The purge valve overlaps the vehicle body frame when viewed from the side of the vehicle. In this case, it is possible to prevent the canister from being directly impacted when the vehicle falls, and the appearance can be improved.

The canister does not have to overlap the throttle body in the vehicle plan view. In this case, the hoses arranged around the canister can be efficiently arranged.

The saddle-mounted vehicle may further include a starter motor attached to the engine and a holder. The holder may integrally hold the canister, purge valve and starter motor. In this case, the holder allows the purge valve to be placed near the canister, so that the hose connecting the purge valve and the canister can be shortened. In addition, it is possible to suppress an increase in the number of parts.

The purge valve may include a connection port extending forward and downward toward the head pipe and to which a hose is connected. The hose may include a first portion that is connected to the connection port of the purge valve and extends forward and downward toward the throttle body, and a second portion that extends forward and upward from the first portion. In this case, it is possible to prevent gasoline from accumulating and sticking to the connection port.

The throttle body may include a connection port to which a hose is connected. The connection port of the throttle body may be arranged above the connection port of the purge valve. In this case, the volatilized gasoline is easily guided to the throttle body.

The throttle body may further include a throttle. The connection port of the throttle body is arranged in front of the throttle and may extend forward and upward toward the head pipe. In this case, the volatilized gasoline is easily guided to the throttle body.

The saddle-mounted vehicle may be connected to the canister at the rear of the engine and may further be equipped with a discharge hose for exhausting the canister's air. In this case, it is difficult for rainwater coming from the front to catch on the discharge hose during traveling.

According to the present invention, it is possible to provide a Norikura-type vehicle capable of efficiently arranging a hose connecting a purge valve and a throttle body.

In the saddle-mounted vehicle 100 according to this aspect, the canister 30 is arranged behind the throttle body 23, the purge valve 40 is arranged above the canister 30, and the purge valve 40 is arranged in the vehicle front-rear direction with the throttle body 23 when viewed from the vehicle side. Overlap. Therefore, since the purge valve 40 can be arranged at a position close to the throttle body 23, the first hose 51 connecting the throttle body 23 and the purge valve 40 can be shortened. As a result, the first hose 51 can be efficiently arranged. Further, since the canister 30 is arranged below the fuel tank 7, the third hose 53 connecting the canister 30 and the fuel tank 7 can be shortened.

Since the canister 30 and the purge valve 40 are arranged inside the vehicle body frame 2, it is possible to prevent the canister 30 from being directly impacted when the vehicle falls or the like.

Since the purge valve 40 overlaps with the vehicle body frame 2 when viewed from the side of the vehicle, it is possible to prevent a direct impact on the canister 30 when the vehicle falls or the like, and it is possible to improve the appearance.

Since the canister 30 does not overlap the throttle body 23 in the vehicle plan view, the first to fourth hoses 51-54 arranged around the canister 30 can be efficiently arranged.

Since the holder 60 integrally holds the canister 30, the purge valve 40, and the starter motor 56, the purge valve 40 can be arranged near the canister 30. As a result, the second hose 52 connecting the purge valve 40 and the canister 30 can be shortened. In addition, it is possible to suppress an increase in the number of parts.

The first hose 51 connecting the throttle body 23 and the purge valve 40 is connected to the first connection port 40c of the purge valve 40 and extends forward and downward toward the throttle body 23, and forward from the first portion 51a. And includes a second portion 51b extending upward. As a result, it is possible to prevent gasoline from accumulating and sticking to the first connection port 40c.

Since the connection port 23b of the throttle body 23 is arranged above the first connection port 40c of the purge valve 40, the volatilized gasoline is easily guided to the throttle body 23.

Since the connection port 23b of the throttle body 23 is arranged in front of the throttle 23a and extends forward and upward toward the head pipe 11, the volatile gasoline is easily guided to the throttle body 23.

Since the fourth hose 54 is connected to the canister 30 behind the engine 6, it is difficult for rainwater coming from the front to catch on the fourth hose 54 during traveling.

Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and various modifications can be made without departing from the gist of the invention.
