1416号公報、実開昭56−85024号公報参照。Motorcycles are equipped with an engine in the lower front part of the frame. In general, a carburetor is disposed on the rear side of the engine cylinder, and an air cleaner is further connected on the rear side of the carburetor. In this way, the fuel from which the dust has been removed by the air cleaner is atomized and mixed by the carburetor to produce intake gas, which is sucked into the engine. In high-speed motorcycles, a streamlined cowling is attached from the front to the front side of the frame, and the cowling is covered with the cowling to reduce wind resistance during traveling. In that case, the engine is located inside the cowling and a ventilation opening is provided in front of the cowling, but the ventilation is not sufficient.
In particular, the temperature of the cylinder portion of the engine becomes high due to the combustion heat generated by the operation, and the temperature around the cylinder rises. When the air with the increased temperature is sucked by the air cleaner, the air is expanded due to the increased temperature and the air density is low, so that the intake efficiency is reduced and the engine output is disadvantageously reduced. In order to prevent this, the wind guide pipe connected to the inlet of the air cleaner is guided to the front of the car body and opened to the front of the cowling, so that air that can travel can be sucked into the air cleaner. However, there is a problem that when the speed is increased, the supercharging is performed, and the setting and the mismatch of the carburetor are caused, and the output is reduced. Some marine engines cool the intake air with water. For example, Japanese Utility Model Application
See JP-A-1416 and JP-A-56-85024.

目的とする。This invention provides a water-cooled cylinder at the inlet of the air cleaner to water-cool the intake air, and arranges a cooling water passage so as to be inexpensive and unobstructed by using a radiator and a frame pipe provided at the front, It is an object of the present invention to obtain an air-cooled air-cooled air cleaner capable of improving a cooling effect and reducing intake noise by providing a honeycomb-shaped cooling fin in a body.

The cylinder 3 is arranged vertically, and a carburetor 5 is connected to the rear side of the cylinder head 4, and an air cleaner 6 is further connected to the rear side of the carburetor 5. A cowling 7 is attached so as to cover the frame 2 over the front surface and the left and right front side surfaces of the frame 2. The air cleaner 6
The cylinder 10
Is provided and it is an inlet. The cylindrical body 10 is hollow so that cooling water can pass therethrough. A cooling fin 11 formed in a honeycomb shape is provided inside the cylindrical body 10. The cleaner element 12 is provided so as to surround the cylindrical body 10, and when air passes from the inside to the outside, dust is trapped. An outlet 13 is provided at the front end of the cleaner box 9 and is connected to the vaporizer 5. A radiator 14 is attached to the front of the cowling 7 so as to face forward. As shown in FIG. 3, the left and right main tubes 15 of the frame 2 have a plurality of holes.
The pipe 16 is divided into 16 parts, and one of the holes 16 is used as a cooling water channel, and is connected to the radiator 14 and the cylinder 10 with a hose 17 to form a circulation path. Circulation pump 18 in the middle of hose 17
Or natural convection may be provided.

るのを防ぐこともできる。The cylindrical body 10, which is the suction port of the air cleaner 6, is provided rearward, so that stable suction can be performed without being affected by wind due to running. Even when the hot air near the engine 1 is sucked, it is cooled by the inner surface of the cylindrical body 10 and the cooling fins 11, and the air density is not reduced, so that a decrease in output due to a decrease in intake efficiency can be prevented. The warmed cooling water is circulated to the radiator 14, and the cooling is performed by the wind caused by traveling. The cooling water passage between the radiator 14 and the cylinder 10 of the air cleaner 6 is provided by the main tube of the frame 2.
If the 15 holes 16 are used, the hose 17 can be shortened, and piping can be performed without obstruction. The honeycomb-shaped portion of the cooling fin 11 can also prevent the intake noise due to the rapid intake from leaking to the outside.

インは、吸気騒音の洩れを防ぎ、静かにできる。As described above, in the present invention, the cooling fins are arranged in a honeycomb shape inside the cylindrical body containing the cooling water therein, and the cylindrical body is provided at the entrance of the cleaner box, and is disposed forward at the front end of the vehicle body. Since the radiator and the cylinder are connected by the cooling water passage, the cylinder at the suction port can be made to face backward, so that it is not affected by the wind due to traveling, and the intake air is stabilized. Further, even if hot air near the engine is sucked in, it can be cooled by the cooling fins when passing through the cylinder, so that the air density can be prevented from decreasing and the output can be prevented from lowering. The piping of the cooling water passage can be simplified by using a part of the frame. Further, the honeycomb-shaped cooling fins can prevent the noise of the intake air from leaking and can be quiet.
