Recently learned，The engine as the small heart of the car，The power comes from the combustion of the oil; the engine structure is very precise，So especially "delicate"，Very small impurities will damage it，Whether it's gasoline、Oil or air，Entering it must be filtered layer by layer。I want to focus today，is the "nose" of the engine -air filter。

The role of empty filtration is to finely filter the air entering the engine cylinder，Filter the wind sand in the air and some suspended particles，Make sure that the air entering the engine is relatively pure。Whether the air filter can keep clean and unobstructed the life of the engine。

In actual work，When the filter element of the air filter is blocked by the suspended particulate matter, when the air flow of the air required for engine work cannot be met，The engine will "breathe out"，Work status will be abnormal:

1. The sound of roar is stuffy，Specific acceleration (insufficient air intake and insufficient pressure in the cylinder);

2. Powerful work (incomplete combustion due to excessive mixed gas);

3. The water temperature is relatively elevated (burning is still continuing when entering the exhaust itinerary);

4. The exhaust smoke becomes thicker during acceleration (the inadequate air flow causes incomplete seabet myburning for a short time);

When these symptoms appear，Disassembling filter element should be considered，Maintenance or replacement。

Stalling parking
Make sure that the vehicle will turn off and cool down for 15 ~ 20 minutes，Open the engine compartment cover，Find the position of the air filter。The air filter is generally located on the right side of the engine cabin，You can view the location logo on the vehicle's manual。

Take the filter element
Open the filter cover lock，Remove the nut of fixed cover，Open the baffle，Take out the filter element。When taking out the filter element，Pay attention to prevent impurities from falling into the carburetor。

Cleaning filter
Check whether there are more dust in the filter element，You can use compressed air to remove the dust on the filter element from the inside out。If there is no compressed air，You can use a handle to gently tap the filter element，Use a brush to clean the external dirt。Now the car is generally used in dry paper filter，Do not use gasoline or water washing。
After removing dust，If the outer surface of the filter paper is clear，and when the inner surface is bright，This filter element can be continued;，need to be replaced!

Installation
After the filter element is cleaned，According to the order of the opposite of disassembly，Install each component。

Do not seek quality when buying
Since the minority maintenance personnel did not recognize the importance of the air filter，Only the picture is cheap，No quality，Buy at will，As a result, the engine will appear abnormal soon after using the engine。Especially when there are more fake and shoddy products in the current market，More Shopping than three，Careful purchase，Always adhere to the principle of quality first。

Randomly dismantle in use
The engine must use an air filter，This is a scientific basis。but，Some drivers will dismantle the air filter at will，Make the engine directly sucked into the unique air work。The test of the cargo car removal of the air filter shows that after removing the air filter，The engine cylinder wear will increase 8 times，Pistons will increase by 3 times，The wear of the piston ring increases 9 times。

Maintenance and replacement does not start from actual
In the instructions of the air filter，Although the data is stipulated as a data for mileage or working hours as maintenance or replacement。But in fact, the maintenance and replacement cycle of the air filter is also related to environmental factors。Car that often drives in an environment with a large dust content，The maintenance or replacement cycle of the air filter should be shorter; the car in an environment with a small dust content，The maintenance or replacement cycle of the air filter can be appropriately extended。

In actual work，Many driving repair personnel mechanically work in accordance with regulations，Different flexible grasp of different environmental factors，It is necessary to wait until the mileage of the driving is obviously abnormal when the engine work is obviously abnormal。Notice，Care at this time，Not only cannot recover the losses that have been caused，and it will cause greater harm。Even more，Individual drivers do not know that the air filter will fail，As long as it is not damaged outside, continue to use。

I am not a maintenance person，Why do you know about so many small parts?

The most direct effect is stop loss.
When we understand why empty filtration will dirty，When should I change it，can be maintained and replaced more reasonably，Make sure the performance of the engine is stable and play，Reduce damage caused by air miscellaneous seabet loginand small to the engine。
