An air filter is a device used to filter impurities from the air and is mainly applied in equipment such as internal combustion engines and ventilation systems. The following is the detailed information about air filters:
Working principle
The core component of an air filter is the filtering medium. Common filtering media include filter paper and fiber filter screens, etc. When air passes through the air filter, impurities (such as dust, pollen, sand grains, etc.) will be intercepted by the filter medium, while clean air can pass through and enter the engine or other equipment that requires clean air.
For instance, in the air filter of a car engine, during the intake process, air is drawn into the filter. Larger particles of impurities are first blocked near the intake port of the filter, while smaller particles are adsorbed or intercepted as they pass through multiple layers of filter paper or fibers, ensuring that only clean air enters the engine combustion chamber to participate in combustion.
Main function
Protect the equipment
For internal combustion engines (such as those in cars, motorcycles, generators, etc.), it is crucial to prevent dust and other impurities from entering the engine. If impurities enter the engine, it will lead to accelerated wear of engine components. For instance, the friction between the piston and the cylinder wall will become more intense due to the presence of impurities, reducing the engine's service life.
In industrial ventilation systems, air filters can prevent dust from entering the working area and protect precision instruments and equipment from contamination. For instance, in an electronic chip manufacturing workshop, a clean air environment is one of the key factors in ensuring chip quality. Air filters can effectively filter out impurities that may damage chip manufacturing equipment.
Improve efficiency
In internal combustion engines, clean air can ensure a more precise mixture ratio of fuel and air. When the air filter is functioning properly, the engine can draw in a sufficient amount of clean air to ensure complete fuel combustion, thereby enhancing the engine's power output and fuel economy. For instance, a clogged air filter can cause insufficient air intake to the engine, leading to incomplete fuel combustion and a reduction in engine performance.
