In order to improve the problem that the conventional intake pipe group is disposed outside the air cleaner, the air filter has limited space and the vehicle cannot be miniaturized, the present invention extends the air inlet pipe into the second chamber to make the air filter The volume can be expanded as much as possible, and the overall configuration of the engine can be compacted and compacted, and the air inlet can be installed as the inlet pipe extends to the inside of the air filter and extends as close as possible to the filter device. The gas of the device can be quickly exported to the engine through the filter element.

At the same time, in order to block the external dust and water from entering the air inlet pipe, an outer cover is arranged at the air inlet of the casing and covers the air pipe, and the air inlet opening formed between the outer cover and the casing and the hollow box is hollow The tank, that is, the intake opening, is toward the center of the vehicle. Therefore, the air inlet pipe can effectively block the external sand dust and water from directly entering the air inlet pipe due to the cover of the outer cover. In addition, the air inlet opening is toward the center of the vehicle, and the sand dust and water from the outside of the vehicle can be prevented from being directly introduced during the running of the vehicle. Into the air tube. With the above configuration, the overall configuration of the engine can be more compact and compact, and the sand and water can be blocked, without sacrificing the storage space inside the original vehicle or limiting the design of the vehicle. To prevent sand and water from being sucked into the air filter by the air filter, causing the engine to malfunction or affect the life of the engine.

The outer cover and the casing may be combined by using an adhesive, or a shackle is protruded from the air inlet of the casing, and the outer cover is locked to the shackle, wherein the shackle is blocked. The sheet and the shell may be of a unitary structure, and may have an edge extending along the edge of the shell and the hollow box, and extending outwardly in parallel to block a part of the sand and water directly sprayed from the outside to the engine. The housing flows to the air inlet.

In addition to the locking method, a plurality of engaging pins may be disposed on the 挡-shaped blocking piece, and the outer cover has a plurality of openings corresponding to the plurality of engaging pins, so that the plurality of openings of the outer cover can be correspondingly engaged to The plurality of snap-in pins of the 挡-shaped flap are fixed by the snapping manner. At this time, the outer cover can be an elastic rubber outer cover, and can be assembled without using a tool to improve the assembly convenience.
