How do you maintain your air filter in a little thumb auto repair?

Modern automobiles mostly use paper air filters, which have high filtration efficiency and dust transmission rate. The use of paper air filters reduces wear on cylinders and pistons and extends engine life. The following points should be paid attention to when using and maintaining:

1) Master the characteristics and cleaning methods of paper filter cartridges. These cartridges are made of microporous filter paper with a treated surface. When the engine is working, the air filters out the dust through the micropores, ensuring that clean air enters the cylinder.

During use, a layer of dust will adhere around the filter element, and no water or oil should be used when cleaning to prevent oil and water from contaminating the filter element.

There are two commonly used cleaning methods: Tap method, that is, take the filter element out of the shell, gently pat the end face of the paper filter element to make the dust fall off, and do not knock on the outer surface of the filter element to prevent damage to the filter element. Purging method, that is, using compressed air to blow from the inside of the filter element to the outside to blow the dust away.

To prevent damage to the filter paper, the compressed air pressure must not be exceeded.

2) Clean and replace the filter cartridge regularly. In use, the air filter element should be cleaned frequently according to the car maintenance regulations, so as to avoid increasing the air intake resistance, reducing engine power and increasing fuel consumption due to excessive dust adhering to the filter element. If the filter element is damaged, it should be replaced in time.

3) Install it correctly to prevent air from entering the cylinder without filtration. When inspecting and maintaining your air filter, the gasket on the filter must be properly installed. If the gasket has been aged, deformed or broken, it should be replaced with a new one.

4) When replacing the new filter element, the original ** filter element should be selected, do not use inferior filter element, generally can identify high-quality and inferior filter elements from the packaging and appearance, and can also be inspected after installation, such as after installing the new filter element, the CO emitted by the car exceeds the standard, and the CO emission when the filter element is not installed, indicating that the filter element has poor air permeability and is an unqualified filter element. When buying a filter cartridge, remind everyone to buy it in a regular auto parts store, otherwise it is easy to buy fakes.

Blow it clean with an air pressure of about 5 atmospheres.

1. External maintenance: clean the whole body up and down front and back, check it once, repair defects, and do a waxing beauty maintenance.

2. Engine maintenance: engine cleaning, check the addition of oil, brake oil, and antifreeze for insufficient use, and replace it after expiration. ⊿◆

3. Tire maintenance: check whether the tire has scratches, bulges and clean up the inclusions in the tread, and appropriately increase the tire pressure compared with summer.

4. Battery maintenance: check whether the battery shell is bulging and damaged, whether the battery water is sufficient, whether the electrode wiring is dry and clean, if the electrode is found to have green oxide, it must be rinsed off with boiling water. ⊿◆

Engine lubricants are constantly contaminated by metal shavings, dust in the air, and carbon deposits during use. Among them, the heavy impurities are precipitated at the bottom of the oil pan, and the light ones enter the friction surfaces with the lubricating oil, causing early wear of the parts. The function of the oil filter is to pass the lubricating oil through the filter to remove dirt.

After a certain period of use, a lot of dirt will adhere to the filter element, so the filter should be replaced regularly. As a general rule, the oil filter should be changed at the same time as the oil. In this way, it is beneficial to extend the service life of the engine.

For cars that are used frequently, the oil filter should be replaced every 7500km driven. In bad conditions, such as frequent driving on dusty roads, it should be replaced every 5000 km. The precautions for changing the oil filter are as follows:

1) Use an oil filter wrench or an appropriate tool to remove the filter to prevent damage to the threads at the connection part.

2) Check and clean the oil filter mounting surface. Otherwise, it is easy to produce oil leakage after installation, resulting in insufficient oil supply.

3) When installing the oil filter, a layer of oil should be applied to the surface of the sealing ring to ensure reliable sealing and prevent damage to the sealing ring.

4) After starting the engine, check the height of the lubricating oil surface, if the oil volume is insufficient, the oil should be replenished according to the regulations.

First of all, pay attention to the retention interval of the oil filter.

The fuel filter is recommended to be replaced every 10,000 km, and the built-in fuel filter in the tank is replaced for 4,800 km.

There may be slight differences between different models, so please know when your car needs to be replaced and serviced through the "Self Service" function. During major maintenance, the combustion filter is generally replaced at the same time as the oil, machine filter, and air filter.

The disassembly, assembly and replacement of the combustion filter is more complicated, so it is not easy to operate it yourself, and it needs to be operated and installed by the professionals of the special store.

The air filter must be cleaned when the car's mileage reaches the interval specified for air filter maintenance, or when the air filter is clogged (regardless of the mileage).

Clean the air cleaner. Loosen the filter latch, remove the nut holding the filter in place, remove the cover and pull out the filter. Take out the filter element, pay attention to the slippery state to prevent impurities from falling into the carburetor. Wipe the inside and outside of the air filter case with a cloth dipped in gasoline.

Check the level of contamination of the filter element and clean it for leakage. When the filter element accumulates dry dust, compressed air with a pressure of no more than 500kPa can be used to blow the dust on the inner and outer surfaces of the filter element evenly along the bevel direction from the inside of the filter element. If compressed air is not available, use the screwdriver handle to gently tap the filter and use a brush to clean the external dirt.

The three filters do not need to be cleaned, and there is no need to clean, just change them!

1) Simply adjust the vehicle deviation to increase the front wheel pressure in the direction of deviation, or adjust the tire pressure in the other direction, and use the tire pressure to adjust. Tanzhi.

2), to prevent the external reversing mirror water storage method and the same as the muffler, the lack of chaos is to let the accompaniment Min make a small hole under the rearview mirror (a little bigger is fine, it has no impact on the appearance, you will find that every time after washing the car or when it rains heavily, the rearview mirror will have water sprinkled on your body, causing trouble. )

3) What to do if the brake is not as easy to use as before When parking or waiting for the red light, you can recover by stepping on the brake with a few feet, this is because the slack of brake pads is greatly relieved, and it can be basically restored after stepping on it vigorously.
