Air filter for motor cycle

Abstract

The present invention discloses a motorcycle air filter which comprises an air filter casing, an air filter cover, an air filter filtering core, an air inlet pipe and an air outlet pipe, wherein, the air outlet pipe is connected with an air outlet at the wall of the air filter casing; the air filter casing is buckled with the air filter cover; the air filter filtering core is arranged in an inner cavity formed by the air filter casing and the air filter cover; the air filter cover and the air inlet pipe are in an integral structure; the end of the air inlet pipe is open; a tubular air inlet connecting piece is assembled at the air inlet pipe by the open end of the air inlet connecting piece; the closed end of the air inlet connecting piece is provided with an air inlet. The motorcycle air filter can ensure that sufficient air enters into a carburetor, and the air and gasoline are atomized and mixed in the carburetor with good effect by reducing the air inlet resistance of the air filter and enlarging air inlet quantity, so that mixed gas enters into the engine and can burn entirely; the power and the torquemoment of the engine are all ensured; the motorcycle air filter reduces fuel consumption and also effectively reduces the tail gas emission at the same time.

Description

technical field [0001] The invention belongs to the technical field of motorcycles, and in particular relates to a motorcycle air filter. Background technique [0002] The structure of a general motorcycle air filter is as follows: Figure 4 As shown, it consists of an air filter housing 1, an air filter cover 2, an air filter element 3, an air intake pipe 4 and an air outlet pipe 5. An air outlet is opened on the wall of the air filter housing 1, and the air outlet pipe 5 is connected to the air outlet pipe. The air outlets are connected. The air filter cover 2 and the air filter housing 1 are fastened together and fixed together by screws, and the air filter element 3 is located in the inner cavity formed by the air filter cover 2 and the air filter housing 1 . The intake pipe 4 and the air filter cover 2 are integrally formed by injection molding, and the end of the intake pipe 4 is sealed, and two air intakes 4a are symmetrically opened on the wall of the intake pipe 4 ...

AI Technical Summary

Problems solved by technology

Since the center line of the existing air inlet 4a is perpendicular to the axis line of the air intake pipe 4, the air intake resistance is large, the air intake volume is relatively small, and the atomization and mixing effect of air and gasoline in the carburetor is poor. When the mixed gas enters the engine, it cannot be fully burned, the power and torque of the engine are affected, and the fuel consumption is high, and the exhaust emission is also high.

In addition, since the air intake pipe 4 and the air filter cover 2 are integral structures, the same type of air filter can only be matched with the corresponding carburetor and muffler. To match the carburetor and muffler of other displacement models, the muffler must be rebuilt Change the size of the air inlet 4a, because the mold is larger, it will inevitably lead to difficulty in mold repair, and the cost of mold repair is higher
