Automobile engine is very precise parts, the tiny impurities will damage it, and the air cleaner is to ensure access to the cleanliness of the air to the engine important parts. It is equivalent to the human nose is air entering the engine to go through the first hurdle, the role is to enter the engine cylinder air of the fine filter to filter out sand in the air and some suspended particles, so that the air entering the engine is pure. Therefore, the air filter can maintain clean and smooth relationship between the engine life.

Often after a variety of construction points of the road, dust rolling easily lead to clogging of the air filter. If the air filter is too dirty to clean up in a timely manner, it will affect the engine intake is insufficient, incomplete combustion of the fuel, eventually leading to engine instability, loss of vehicle power and fuel consumption increase phenomenon.

Clean air conditioner filter regularly

If the air filter is the "nose" of the car, then the air conditioning filter is directly related to whether the passenger's nose in the car can breathe healthy air.

Under normal circumstances, air conditioning filter can be filtered from the outside into the inside of the air, so that the cleanliness of the air to improve, to ensure the health of passengers in the car. It is very important to maintain the cleanliness of the air conditioner filter if the vehicle is often through the dusty road. Temperatures in the winter cold, some car owners closed the window, only open the inner circulation is not open air conditioning, master said that this approach is not correct, driving for a long time will cause the in car air pollution, bring certain risks to human health.

Normally, the vehicle traveling 8000 km ~10000 km space filter need to be replaced once, usually only need to be cleaned regularly in each season can be, especially after the winter. Air conditioning filter can also do it yourself cleaning, it is not difficult.

Air filter how to maintain?

According to the maintenance cycle of the vehicle, in the general road conditions, the car every 5000 kilometers on the road to deal with air filter cleaning and maintenance. Corresponding relationship maintenance interval mileage, the master recommended in advance to every 3000 kilometers clean up in the area of dust is larger, the air quality in the surrounding environment is poor. General car air filter in the car for 20 thousand kilometers to change once.

DIY clean air filter

Tools: screwdriver

1 stall parking. Ensure the vehicle flameout cooling for 15~20 minutes, and then open the bonnet, find the position of the air cleaner. Air cleaner is generally located on the right side of the engine room, you can see the location of the vehicle use manual identification.

2 take the filter element. Open the filter cover lock nut, fixed cover open baffle, remove the filter element. Remove the filter, should pay attention to prevent impurities fall into the carburetor.

3 cleaning filter element. Check whether there is more dust filter, you can gently tap the filter core face, you can use compressed air from the inside out to remove the dust on the filter. If there is no available compressed air, the screwdriver handle gently tap the filter, and then brush the hair net external dirt. Do not use gasoline or washing brush.

If the air filter has been seriously blocked it needs to be replaced.

4 after cleaning the filter core, according to the contrary order, the parts will be installed.

Note: the car widely used dry air cleaner, dry air filter cartridge is made by processing through resin microporous filter, filtration effect is good, the price is cheap. Different types of air filter maintenance methods are basically the same.

But because of the different models of the air filter is not the same. If you choose to replace the air filter, it is best to go to a high degree of credibility of the parts dealer to buy.

Filter is the replacement of one of the highest frequency of parts in car maintenance. This filter contains oil filter, air filter, fuel filter, three important components of engine maintenance. Here to talk about the role of fuel filter and the replacement of conservation issues.

The fuel filter is arranged on the pipeline between the fuel pump and the throttle valve body inlet.

The role of fuel filter

Fuel filter, containing solid fuel in the iron oxide, dust and other debris removed to prevent fuel clogging (especially nozzle), reduce mechanical wear and to ensure the stable operation of the engine, and improves the reliability, fuel filter structure is composed of an aluminum shell and a stainless steel stent, on the bracket with efficient filter assembly and filter paper as a chrysanthemum shape, to increase the flow area.

General EFI carburetor and can filter filter. Because the filter often bear 200 ~ 300kPa EFI fuel pressure. Therefore, the compressive strength of the filter general requirements above 500kPa, carburetor filter can not meet the requirements.

Fuel filter replacement cycle

The fuel filter must be replaced once every 30 thousand km (conservative replacement mileage 15 thousand km). If the fuel impurity content, driving distance should be shortened accordingly. The fuel filter shell on the arrow indicates the direction of flow of fuel, fuel filter installation, are not allowed to flip. Even if it is in a very short time inversion work must also be replaced. By car manufacturers of different models of the maintenance cycle is not exactly the same, the replacement cycle to car manufacturers should prevail.

Fuel filter discrimination is very difficult, ordinary consumers do not do. Generally speaking, authentic products, packing quality are better, the packing box on the handwriting clear, overprint bright colours and marked with product name, specification, quantity, registered trademark, factory name, address and telephone number, etc., have qualified certificate and inspectors chapter.

As we all know, the domestic gasoline quality is uneven, the maintenance of the fuel filter can not be ignored. In fact, the role of the fuel filter is to filter impurities in the automotive fuel, so that the supply of fuel to the engine burning more pure.

How often is the fuel filter changed?

Fuel filter is recommended to replace once every 10 thousand km, the fuel filter 4~8 million to replace the fuel filter. The differences between different models of maintenance cycle may be slightly, your car when need replacement and maintenance, please understanding through self maintenance function.

Large maintenance, fuel filter and oil filter, filter, filter, air filter at the same time to replace.

The installation and replacement of the fuel filter is more complicated, do not easily operate, need to be operated by the special staff of the shop installation.

Necessity of replacing fuel filter

Fuel filter according to the different fuel can be divided into gasoline and diesel fuel filter, household car is mainly used in gasoline filter, gasoline filter and fuel tank built-in and external.

Vehicle with the growth of age, driving (ginseng, pictures, inquiry) mileage increases, fuel filter for a long period of time, arrived at the certain life cycle, will lead to car speed powerless, increased fuel consumption, increased noise, control performance decreased.

Fuel filter to choose to pay attention to matters

1, the purchase of goods, please be sure to check the car models, displacement and other information, to ensure that the correct type buy accessories. You can check your car maintenance manual, can be used according to the car worry free network "self maintenance function".

2, the fuel filter in large maintenance, general and oil, machine filter, air filter at the same time to replace.

3, the selection of high quality fuel filter, poor quality fuel filter often lead to poor fuel supply, lack of power and even off the car. Impurities are not filtered for a long time, and the oil circuit and fuel injection system will also be damaged.

4, when the feeling of speed is significantly reduced, the engine speed up the bad, when the car is unable to travel, it is possible to think of the fuel filter may have been blocked, need to check in time.

A dirty air filter will reduce the service life of your car, change your air filter, is really important. A little common sense today and share my replacement of air filters!

step

The air filter 1, the old first throw away;

2, open the hood of your position, check the owner's manual air box;

Gas box 3, you find that there should be a clip or a screw sealing box is closed;

4, screw or loosen the box, so that you can see your car's air filter;

5, the cover is opened, the air filter is to show;

6, open it, remove the old air filter, and compare the size and size of what is different;

7, install the new air filter to ensure that it meets the comfort and fit;

8. Close the box and close the cover.

Fuel filter is to remove the iron oxide, dust and other solid debris in the fuel, to prevent fuel system blockage, reduce mechanical wear and tear, to ensure stable operation of the engine, improve reliability. Filter is a "dirty" parts, in the use of a period of time, the fuel filter will need to be replaced. So, how to replace the specific, the replacement process should pay attention to what it?

Fuel filter replacement cycle

Most car manufacturers to the external filter of the normal maintenance of the recommended replacement cycle for the replacement of KM; a conservative maintenance recommended replacement cycle is 1.92 ~ km. If you are not sure, please read the owner's manual to find the correct recommended replacement cycle. In addition, when the filter hose appears from dirt, oil and other dirt caused by aging or cracks, need to replace the hose in a timely manner.

Fuel filter (FuelFilters) is recommended replacement cycle should be according to its structure, properties, and uses of the different and somewhat difference, and can not be generalized. If the filter is installed in the fuel line, it is called the external filter (External); on the contrary, the internal filter (Internal) is installed in the fuel pump and the fuel tank inside the filter. The fuel tank filter or the protective sleeve is generally considered to be a maintenance free component.

Fuel filter replacing method

First, relax oil and fuel filter with the clamping device, then removed from the oil in the fuel filter, followed by a stopper circuit, so that you can prevent spillage of fuel.

Most are installed in the oil in the fuel filter are marked with two arrows, one is the fuel into the arrow, the other is a fuel out of the arrow, use the arrow to indicate when the flow of fuel through the fuel filter. So when we install the fuel filter, make sure the direction of the arrow pointing to the engine, which is the flow of the engine oil.

In addition, it should also be noted that the clamping device used in oil is designed, the rubber hose and fuel filter at the combination of these two parts tightly, to achieve the sealing effect. Compared with the ordinary clamping device, the clamping device will cut rubber hose, so it will not cause the damage to the rubber hose, and the clamping device can withstand high pressure. Finally, we should also ensure that the rubber hose clamping device is installed at the correct position and in accordance with the specifications specified junction clamp.

Note: many of the imported fuel filter is a combination of Pipa shaped parts, through the combination part to connect the fuel filter and engine oil. When using the pipa shaped connecting parts, should pay attention to their sealing gasket is does not allow the repeated use of, so for Lute shaped with combined with part of the fuel filter, each maintenance must replace the gasket, to prevent oil leakage.

In addition, this should also pay attention to the combination of Pipa shaped parts, during the installation process can make the connecting thread wrong button, nor in the combination of components exert too big clamping force. In these parts with Pipa shaped sealing ring do not use RTV or other types of. In the installation of the connecting parts, should use the wrench to ensure appropriate clamping force.

If the vehicle is without the need to maintain the fuel system, and only use a built-in to the fuel filter, then in vehicle periodic preventive maintenance process, it is not possible to the oil pump, a filter and a fuel output device all replaced, even automotive preventive maintenance interval is long, it is impossible to do that, because of the high cost of doing. However, if there are signs of abnormal engine performance, or fuel system pressure at the critical value, then check or replace the fuel filter on the inside of the tank is necessary.

After the completion of the maintenance work for the fuel filter to the assembly of all parts and re installed on the fuel pump fuse, then in the ignition system does not work, so that the engine rotates for several laps, until the fuel system in the establishment of the normal fuel pressure so far. At this time, should check the fuel filter and oil leaks. If the test results show that everything is normal, start the engine running a few minutes, and then re check again, to ensure that no leakage happens.

Fuel filter maintenance and replacement is relatively complex, unlike air filter that is easy to operate, but we cannot so will neglect to check the maintenance, otherwise on the fuel filter had no effect.
