Background technique

The air filter, referred to as the air filter, is located in the engine intake system and is a device for purifying the air. It consists of a housing and a filter element, and the filter element is arranged in the housing. The function of the air filter is to filter the dust and impurities in the air. For example, it provides clean air to the engine cylinder, reduces the wear of sundries on pistons, cylinders and other devices, and ensures the normal and efficient operation of the engine, which has a great positive effect on engine maintenance. Just like the human nasal cavity, the air filter is the "nose" of the engine.

The self-stirring wet air filter is also called the oil bath air filter, which is to introduce the sucked dusty air into the oil pool to remove most of the dust, and then the air with oil mist flows upward through a metal wire wound air filter. When the finished filter element is used for further filtration, the oil droplets and the trapped dust return to the oil pool together. However, if the airflow velocity is fast, the air will pass through the oil too fast, which will make the filtration incomplete, and with the loss of oil, the liquid level will drop, and the airflow will enter faster and more, making the oil Can not fully contact with the gas, can not effectively remove impurities.
