Car air filter.
Car air filter is an item to remove particulate impurities in the air in the car, car air conditioning filter can effectively reduce pollutants through the heating ventilation and air conditioning system into the car, to prevent the inhalation of harmful pollutants.
Car air filter is mainly responsible for removing particulate impurities in the air. When the piston machinery (internal combustion engine, reciprocating compressor, etc.) works, if the air contains impurities such as dust, it will aggravate the wear of the parts, so it must be equipped with an air filter. The air filter is composed of two parts: a filter element and a housing. The main requirements of the air filter are high filtration efficiency, low flow resistance, and can be used continuously for a long time without maintenance.
The car engine is a very precise part, and the smallest impurities will damage the engine. Therefore, before the air enters the cylinder, it must first pass through the fine filtration of the air filter to enter the cylinder. The air filter is the patron saint of the engine, and the condition of the air filter is related to the life of the engine. If the dirty air filter is used in the car, the engine intake will be insufficient, so that the fuel combustion is incomplete, resulting in unstable engine work, power decline, and increased fuel consumption. Therefore, the car must keep the air filter clean.
The role of the automobile air filter is as follows:
1. Make the air conditioner close to the shell to ensure that unfiltered air will not enter the carriage.
2. Separate dust, pollen, abrasive particles and other solid impurities in the air.
3, adsorption in the air, water, soot, ozone, odor, carbon oxide, SO2, CO2, etc. Strong and durable absorption of moisture.
4, so that the car glass will not be covered with water vapor, so that the passenger line of sight is clear, driving safety; It can provide fresh air to the driving room, avoid the driver and passenger inhaling harmful gases, and ensure driving safety; It can kill bacteria and deodorize.
5, ensure that the air in the driving room is clean and does not breed bacteria, and create a healthy environment; Can effectively separate the air, dust, core powder, grinding particles and other solid impurities; It can effectively intercept pollen and ensure that passengers will not have allergic reactions and affect driving safety.
The difference between automobile air filter and air conditioning filter
1. Function and position
Air filter :
function : mainly filter the air into the engine, prevent dust, sand and other impurities into the engine, protect the engine from wear and damage.
location : Usually installed in the engine compartment, near the engine inlet.
air conditioner filter element :
function : Filter the air entering the car through the air conditioning system, remove the dust, pollen, odor and other harmful substances in the air, and provide passengers with a fresh and healthy air environment.
location : Usually installed in the passenger glove box or near the air conditioner intake.
2. Material and structure
air filter element : usually made of paper or fiber cloth, has a certain filtration accuracy and strength, can resist a certain air pressure, the shape is mostly cylindrical or flat.
air conditioning filter element : according to the different filtering effect, it may be made of paper, activated carbon, HEPA and other materials to achieve better filtering effect, the shape may be rectangular, cylindrical or other shapes.
3. Replacement interval
Air filter :
Generally, it needs to be replaced once every 10,000 to 15,000 kilometers, but the specific replacement cycle needs to be determined according to the use of the vehicle and the driving environment. In areas with heavy wind and dust, they may need to be replaced more frequently.
air conditioner filter element :
The replacement cycle is not completely fixed, and it is usually recommended to change once every 8,000 to 10,000 kilometers, but it can also be flexibly adjusted according to the car environment and seasonal changes. In summer or humid environments, it is recommended to shorten the replacement cycle due to the high frequency of air conditioning.
In summary, the car air filter and air conditioning filter in the role, location, material, structure and replacement cycle are significant differences, owners should be regularly checked and replaced according to the actual situation to ensure the normal operation of the vehicle and the quality of the air in the car.
