[0021] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] like Figure 2-4As shown, a novel engine air filter 1 comprises an air filter housing 1, wherein a filter air inlet 6 is arranged in the air filter housing 1, an engine decorative cover 2 is connected to the lower part of the air filter housing 1, and an air inlet passage 3 is arranged at the connection between the air filter housing 1 and the engine decorative cover 2, the connection between the engine decorative cover 2 and the air filter housing 1 is closed to form a structure for shielding the windward side from the windward side, and the opening of the air inlet passage 3 is arranged at the leeward side of the air filter housing 1.

[0023] In this embodiment, the opening of the air intake passage 3 is set on the leeward side of the air filter housing 1, and the connection between the engine decorative cover 2 and the air filter housing 1 is closed to form a structure for shielding the windward side from the wind. This can greatly reduce the amount of dust and sand in the air that enters the filter 4, thereby providing a certain degree of protection for the filter 4 and reducing the influence of the headwind on the air intake efficiency, making the air intake smoother.

[0024] Furthermore, the interior of the air filter housing 1 is divided into a first cavity 11 and a second cavity 12 , and the first cavity 11 and the second cavity 12 are separated by a partition 7 , and the filter air inlet 6 is provided on the partition 7 .
