Detailed Description

The technical solution of the present invention will be further explained with reference to the accompanying drawings and embodiments.

Referring to fig. 1 to 3, an embodiment of the present invention provides an air intake and exhaust structure for a tricycle, including a mid-longitudinal engine 100, and an air intake system and an exhaust system fixedly mounted on the engine 100; the exhaust system is installed at one side of the engine 100 facing the wind during the running of the tricycle, and the intake system is installed at the other side corresponding to the exhaust system. Specifically, the engine 100 includes an intake port 110 and an exhaust port 120, the exhaust port 120 is located on one side of the engine 100 facing the wind, and the intake port 110 is located on the other side of the exhaust port 120.

Further, the intake system includes an intake pipe 210, a carburetor 220, and an air cleaner 230; one end of the intake pipe 210 is fixedly connected to the intake port 110, the other end is fixedly connected to one end of the carburetor 220, and the other end of the carburetor 220 is fixedly connected to the air cleaner 230. The air is filtered by an air filter 230 before entering the engine 100, preventing impurities from entering the engine 100. The carburetor 220 atomizes gasoline by using kinetic energy of intake air flow, and is then fixedly connected to the intake port 110 of the engine 100 through the intake pipe 210.

Further, the exhaust system comprises an exhaust pipe front section 310, an exhaust pipe middle section 320 and an exhaust pipe rear section 330 which are fixedly connected in sequence; and the exhaust pipe front section 310 is fixedly connected to the exhaust port 120 of the engine 100.
