What is the car air filter?
An air filter is a type of filter, also known as an air filter cartridge, air cleaner, etc. It is mainly used for air filtration in engineering vehicles, automobiles, agricultural vehicles, laboratories, sterile operation rooms, and various precision operation rooms.
During the operation of an engine, a large amount of air is drawn in. If the air is not filtered, the suspended dust in the air will be sucked into the cylinder, accelerating the wear of the piston group and the cylinder. Larger particles entering between the piston and the cylinder will cause a serious "cylinder pull" phenomenon, which is particularly serious in dry and sandy working environments. The air filter is installed in front of the carburetor or the intake pipe and functions to filter out dust and sand particles in the air, ensuring that sufficient and clean air is introduced into the cylinder.
The air filter for automobiles is a key component of the intake system, responsible for filtering impurities in the air entering the engine. Common faults include blockage, damage, and moisture absorption. These faults can directly affect the engine performance and may trigger fault warnings.
The common types of faults of air filters and their impacts are as follows: Blockage is the most common problem. Over time, dust and particles accumulate, increasing the intake resistance and causing insufficient air intake into the engine, thereby leading to a decrease in power, difficulty in acceleration, increased fuel consumption (possibly rising by 5% - 15%), and incomplete combustion resulting in carbon deposits or black smoke. Damage usually occurs due to external force impact or aging, allowing unfiltered air to directly enter the engine, accelerating the wear of internal parts and potentially causing corrosion. Moisture absorption often occurs in humid environments or after water immersion, reducing the filtering efficiency, fostering mold growth, and affecting the air quality inside the vehicle. These faults may also trigger the engine fault light, due to factors such as dirty filters, improper installation, or abnormal sensors (such as the air quality sensor).
To prevent faults, the following measures are recommended: Regularly inspect and replace air filters. For urban driving vehicles, they should be replaced every 1-20,000 kilometers. In high-dust environments, the replacement cycle should be shortened. Also, ensure that the filter is sealed properly to prevent foreign objects or moisture from entering.
Failure to replace the air filter of a car will lead to increased engine wear, increased fuel consumption, decreased power, and poor air quality inside the vehicle. In severe cases, it may trigger engine faults.
Direct damage to the engine
Accelerated wear of key components: Dust and impurities entering the engine act like "sandpaper", rubbing against the piston, cylinder wall, and valves, causing scratches and decreased sealing performance. Failure to replace the filter for a long time can increase cylinder wear by 8 times and piston ring wear by 9 times. Carbon deposits and fault risks: Impurities mixed with engine oil reduce lubrication effectiveness, causing combustion chamber carbon deposits. In extreme cases, it may cause cylinder pull or blockage of the intake passage, triggering the fault light, with repair costs reaching five figures.
Vehicle performance and usage cost issues
Significant decrease in power: Filter blockage reduces the intake volume by more than 30%, resulting in insufficient fuel combustion. This is manifested as slow acceleration, insufficient climbing power, and difficulty in overtaking. Fuel consumption increases by 10% - 15%: The engine compensates for the power deficiency by injecting more fuel. Actual measurements show that after replacing the new filter, the fuel consumption per 100 kilometers can be reduced by 0.8 liters.
Increased emission pollution: Unburned fuel produces more harmful exhaust gases, such as carbon monoxide and hydrocarbons.
