Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention is applied to a ■-type engine mounted on a motorcycle, as shown in FIG. It is placed in such a way that it protrudes from the left and right sides of the vehicle. Therefore, when passenger 6 is seated, leg 5
Since leg 5a interferes with air cleaner 1, passenger 5
It becomes necessary to ride in an open position, which inevitably results in a poor riding position. .

(Objective of the invention) To prevent interference between the passenger's legs and the air cleaner,
To enable a good riding posture, reduce passenger fatigue, and improve safety.

The present invention is equipped with VIM engines, which are generously placed in the front and rear. An air cleaner mounting structure for an engine of a motorcycle, characterized in that the air cleaner is placed in front of the front cylinder to prevent interference between the rider's legs and the air cleaner. be.

(Example) In No. 11iW, which is a schematic diagram of the left side of a motorcycle or a car that employs the air cleaner mounting structure according to the present invention, the ■-type engine 2 fixed to the body frame 10 has cylinders 8.4 [cylinders] at the front and rear. have.

An Fi fuel tank 11 is arranged above the cylinder 8.4, and a seat 12 is arranged behind the tank 11, and the tank 11 and the seat 12 are each fixed to the vehicle body frame 10.

Air cleaners 18 are installed in front of the left and right sides of the front cylinder 3.
is located. As shown in FIG. 2, the air cleaner 18, which has a substantially oval shape extending back and forth when viewed from the side, is mainly made of a hollow resin section, and is fixed to the vehicle body frame 10 by a bracket 14 or the like shown in the figure. As shown in FIG. is open. As shown in FIG. 2, the downstream end of the intake discharge pipe 16 opens at the front side surface of an intake duct 20 made of resin.

The duct 20 extends rearward so as to cover the front cylinder 8 from above, and has two intake communication pipes 21 and 22 on the lower surface above the V bank between both cylinders 8.4. Communication pipe 2
The downstream ends of cylinders 1 and 22 extend substantially downward, and are connected to a capretor 28 for both cylinders 8.4 (only the front cylinder 8 is shown) arranged in the bank. In addition, as shown in FIG. 4, the duct 201 is also made of a relatively flat member in the left and right direction, and by covering the front cylinder 8 from above, the engine 2 is protected against the fuel tank 11 located further above. It is also designed to completely block heat.

As shown in FIG. 3, the intake air is taken in from the rear end entrance of the intake pipe 17, and is passed through the entire air cleaner 13.
The air is filtered and sent to the intake and discharge pipe 16. As shown in FIG. 2, the intake air from the pipe 16 flows rearward in the intake duct 20, is sent from each communication pipe 21, 22 to each capretor 23 of both cylinders, and is mixed with fuel in the carburetor 28. is sent into the descendant cylinder 8.4.

Note that, as shown in FIG.
a does not come into contact with the air cleaner 18. In addition, since the air cleaner 13 does not get in the way of the passenger 5, a sufficiently large capacity can be secured, and combined with the fact that it is placed above the tact 20t engine 2 to obtain a large capacity, the pulsation of the intake air is reduced. There is also less occurrence of 0 sounds “・”′
The air cleaner 18 can be easily approached from the side of the vehicle during maintenance such as replacement of the mesh 15.

(Effects of the invention) Since the air cleaner is cleaned to prevent the passenger's legs from interfering with the air cleaner, (a) the passenger can maintain a good riding posture, reducing fatigue during driving, and improving safety. will improve.

(1) Since the capacity of the air cleaner can be ensured to be sufficiently large, the pulsation of the intake air and the occurrence of -廿□ can be suppressed to a small level.

((3) By covering the cylinder from above with a duct, the heat of the engine is completely isolated from the fuel tank located above.

(Another embodiment) (a) Air cleaner 18t - may be provided only on either the left or right side.

(2) The air cleaner 18 may be fixed to the engine 2 side.

(0) Only one capretor 28 may be provided to serve both cylinders 3.4. In this case, only one intake communication pipe 21, 22t'' can be used.
