Description
Technical Field
The invention relates to the technical field of processing of air filter covers, in particular to an inclined insertion type air filter protective cover.
Background
When the engine is in operation, a large amount of air needs to be sucked, and if the air is not filtered, dust suspended in the air is sucked into the cylinder, so that the abrasion of the piston group and the cylinder is accelerated. Larger particles enter between the piston and the cylinder, causing severe "scuffing" phenomena, which is particularly severe in dry, sandy working environments. The air filter is arranged in front of the carburetor or the air inlet pipe, plays a role in filtering dust and sand grains in air and ensures that sufficient and clean air enters the air cylinder.
Air filters have a significant impact on the service life of automobiles, particularly engines. On one hand, if the air filter has no filtering effect, the engine can suck a large amount of air containing dust and particles, so that the abrasion of an engine cylinder is serious; on the other hand, if the filter element of the air cleaner is not maintained for a long time during use, the filter element of the air cleaner becomes stuck with dust in the air, which not only degrades the filtering capacity but also hinders the circulation of air, resulting in an excessively rich air mixture and an abnormal operation of the engine.
However, since the engine room is narrow and small, when the air cleaner is normally disassembled, an opening is firstly opened between the upper cover body and the lower cover body of the air cleaner protection cover, then the air cleaner protection cover is taken down from the lower cover body and is taken out from a horizontal inclined state to avoid interference of surrounding parts, the process is complex, and certain difficulty is caused by space problems in actual operation.
