What is the car air filter shell
Automotive air filter housing is an important part of the automotive air filter, usually made of plastic or metal. Its main function is to protect the filter element and secure the entire air filter assembly. The inside of the air filter shell is provided with a filter element, which is responsible for filtering the air into the engine to prevent dust, sand and other impurities from entering the engine, so as to ensure the normal operation of the engine .
Structure and function of air filter shell
The inside of the air filter shell usually contains a filter element, which is arranged in the middle of the shell, the front is the front chamber, and the back is the rear chamber. The end of the front chamber is provided with an air inlet, and the end of the back chamber is provided with an air outlet. The housing is also provided with a fixed connecting member, including connecting lugs and connecting holes, for mounting and fixing the filter element . The design of the air filter housing is designed to provide sufficient filtration area and low resistance to ensure that the material and resistance are minimized under the premise of ensuring air flow and quality .
Material and maintenance of air filter housing
The air filter housing is usually made of plastic or metal. With the growth of the use of the car, the air filter element will gradually accumulate dust and impurities, resulting in a decline in filtration performance. Therefore, regular replacement of the air filter element is one of the important measures to maintain the normal operation of the engine . When replacing or cleaning the air filter, it is necessary to remove the filter element, clean the inside and outside of the housing, and then install a new filter element, and ensure that there is no air leakage .
The main role of automobile air filter housing is to protect the engine, prevent dust and impurities into the cylinder, so as to ensure the normal operation of the engine and extend its service life . The air filter housing, also known as the air filter cover, is an important part of the air filtration system. It acts as a barrier, preventing dust from entering the engine directly and ensuring that the engine is sucking in clean air .
Specifically, the role of the air filter housing includes:
Filter impurities in the air : The filter element in the air filter is responsible for filtering the air into the engine, removing dust, sand and other impurities, and ensuring the purity of the air in the cylinder. This helps to reduce the wear of piston sets and cylinders and prevents the occurrence of "cylinder pulling", especially in harsh environments .
Protect the engine : the engine needs a lot of air to participate in combustion when working, if not filtered, suspended dust and particles may enter the cylinder, accelerate wear, and even lead to serious mechanical failure. The air filter housing, through its internal filter element, effectively blocks these impurities and protects the engine from damage .
affects car performance and life : although the air filter itself does not directly affect the performance indicators of the vehicle, the lack of its function or improper maintenance will directly affect the service life of the car. The long-term accumulation of dust in the filter element will reduce the filtration effect, hinder the air flow, lead to the unbalanced mixture, and then affect the normal operation of the engine .
Therefore, regular inspection and replacement of air filters is a necessary measure to ensure stable vehicle performance and extend service life. It is generally recommended to replace the air filter every 5000 km to ensure its best working condition .
