How often should car particulate filters be changed?

Hello According to the environment you use to decide, the conventional 5000 kilometers to change, if it is just a car for work, you can first take it out to see the use of whether to replace, refueling hope to get yours.

Hello friends!

The air filter of the car is replaced every 10000 km, the oil filter is changed every 5000 km with the oil, the gasoline filter is changed 15000 km, and the cabin air filter is replaced 15000-20000 (or a year).

Are you installing an air purifier for your vehicle. If it takes a long time, the air purifier also needs to change the filter.

The replacement time of the air conditioner filter is different for different brands. In fact, the replacement of the air filter element needs to depend on the actual situation, such as the wind and sand in some areas, and there is a lot of dust, so it is recommended that the owner should check the air filter every time he maintains it, and shorten the replacement cycle, and if necessary, he will be guaranteed and replaced. In some cities with relatively clean air, the replacement cycle can be appropriately extended.

In addition, the general air filter element into the water, which indicates that the engine has the possibility of water ingress, this situation is more common in summer when wading, when this happens, it is recommended that the owner turn off the engine first, so as not to cause the engine to enter the top cylinder. You can push out the vehicle, open the air filter shell, clean the water (check whether there is water in the cylinder), it is best to find a regular repair shop to do a simple cleaning, and then it is recommended to replace the air filter with water ingress.

Generally, the car filter element is changed once every 5000-20000 kilometers. MoreoverThere are 4 automobile filter elements, which are oil filter element, fuel filter element, air filter element, and air conditioning filter element.

1. The oil filter element is generally replaced once every 5000 to 8000 kilometers.

2. The fuel filter element is generally replaced once every 1 to 20,000 kilometers.

3. The air filter element is generally replaced once every 1 to 20,000 kilometers.

4. The air conditioning filter is generally replaced once every 20,000 kilometers.

The life of the oil filter element is related to the material, filtration area, strength, etc. of the filter paper, the better the material of the filter paper, the stronger the filtration area, the longer the life of the oil filter element. Generally, the life of the oil filter element is 5000 to 8000 kilometers, and it should be comprehensively judged according to the quality of the oil filter element, car habits, vehicle wear and tear status, and oil quality.

Filter element maintenance.

1. The filter element is the core component of the filter, which is made of special materials and is a wearing part, which requires special maintenance and maintenance.

2. When the filter has been working for a long time, the filter element has intercepted certain impurities, which will lead to an increase in pressure and a decrease in flow, so it needs to be cleaned in time.

3. When cleaning, we must pay attention not to deform or damage the filter element.

Generally, according to the different raw materials used, the service life of the filter element is also different, but with the extension of the use time, the impurities in the air will block the filter element, so generally speaking, the PP filter element needs to be replaced in three months. The activated carbon filter needs to be replaced in six months; Since the fiber filter element cannot be cleaned, it is generally placed at the back end of PP cotton and activated carbon, which is not easy to cause blockage; Ceramic cartridges typically last 9-12 months.

The air filter is about 20,000 kilometers to replace once, if you often run back to a dusty place, it may be replaced at 10,000 kilometers, and you can delay it if you often run at high speed, and the time is generally not seen.

Hello! The time of oil filter replacement is the same as that of oil replacement, generally speaking, the oil is maintained and replaced once every 5000 kilometers, and the filter is replaced at the same time. Different models are required to add different engine oil, for example, some models need to add fully synthetic engine oil, which is replaced once every 10,000 kilometers, and it is recommended to use the maintenance manual of the model as a reference.

The gasoline filter is installed in the oil pipe next to the fuel tank, mainly to filter the impurities in the gasoline, the 4S shop will require 40,000 kilometers to replace, but from the actual use, the current gasoline is relatively clean (unless the oil bottom is added when refueling or there is an oil tank truck in the oil), generally 60,000 kilometers is no problem, of course, you also have to depend on the situation of the engine, if the oil circuit is not smooth, it should also be replaced.

The service life of the machine filter is mainly judged by its filtration capacity, not its own quality. As we just mentioned, if there are more impurities and grease in the oil, they will be attached to the filter paper, blocking the filter holes, causing the oil pressure to become low, and the oil with impurities will directly enter the engine, which is equivalent to the oil not being filtered. In most cases, the service life of our oil filters is 5000 km, and they are aimed at new oil.

In most cases, the filter is changed every 5000 kilometers, but if it is not 5000 kilometers, as long as the oil is changed, the filter is generally replaced together.

The replacement cycle of automobile fuel filter is generally about 10,000 kilometers, and the specific best replacement time can refer to the instructions in the vehicle manual. Usually, the replacement of the fuel filter is carried out when the car undergoes major maintenance, and the air filter and oil filter are replaced at the same time, which is what we call the "three filters" in our daily life.

Regular replacement of the "three filters" is the key way to maintain the engine, which is of great significance to reduce engine wear and ensure its service life.

There are two types of fuel filters, internal and external, and no matter which one they are, they are more complicated to replace, unlike air filters, which can be easily seen and replaced as long as the engine compartment cover is opened. Therefore, it is recommended to go to a professional repair shop and ask a technician to replace it, and do not do it yourself.

<> "Automobile filters include machine filters, air filters, combustion filters and air slag fan filter adjustments. Among them, the air filter and air conditioning filter play a role in filtering the outside air to ensure the cleanliness of the air in the car, and the role of the engine filter and fuel filter is to maintain the quality of the oil and fuel in the car, filter harmful impurities, and ensure the normal operation of the engine.

The function of the filter and the replacement interval:

1. Oil filter.

In order to ensure the cleanliness of the oil circuit, the engine is equipped with an organic oil filter in the lubrication system. In order to prevent impurities from mixing into the oil, causing oxidation and producing gum and sludge to block the oil circuit. The oil filter should be changed at the same time as the oil after 5000 km.

2. Air filter.

The function of the air filter is to filter the dust and impurities that are sucked into the car by the system, and to keep other parts from being damaged by such impurities. It is recommended to replace the air filter every 20,000 kilometers, usually every 5,000 kilometers, do not clean it with water and detergent, and blow it clean with an air pump. If the air filter is not replaced regularly, there is no way to filter and clean such harmful substances normally, so over time, the engine will be affected by dust, which is likely to wear out to the cylinder wall and cause unnecessary trouble.

3. The air conditioner filter is like a locust.

The function of the air conditioning filter is to filter the dust and impurities in the air, to maintain the air inside the car fresh, the replacement time and cycle of the air conditioning filter is generally 8000-10000 kilometers when the car is replaced, can also be determined according to the external environment of the car, if the environment is dry and humid contrast, the climate is dry all year round, the wind and sand are large, can be replaced in advance.

4. Fuel filter.

Remove solid debris in the fuel, such as oxides, particulate dust, etc., to avoid the problem of blocking the car tank in the fuel system such as fuel injectors; In addition, the fuel has a certain lubricating effect, reduces the wear of components, protects the normal operation of the engine, and improves the performance of the engine. The fuel filter is recommended to be replaced every 30,000 km under normal driving. If the fuel impurity content is large, the driving distance should be shortened accordingly.

The main purpose of the car filter is to protect the car from being affected by external factors and ensure that the car can operate normally.

The car filter element is changed once every 2 years.

Automobile filters include air filters, air conditioning filters and gasoline filters, of which air filters and air conditioning filters are replaced once every 20,000 kilometers or 1 year, and gasoline filters are generally replaced once every 40,000 or 2 years. The replacement time of different brands of car filter elements is different, in fact, the replacement of car filter elements depends on the actual situation.

Filters

Filter refers to the accessory that filters impurities or gases through filter paper. Generally, it refers to the car filter, which is an engine accessory.

According to different filtration functions, it is divided into: oil filter, fuel filter (gasoline filter, diesel filter, oil-water separator, hydraulic filter), air filter, air air filter, air filter, etc.

The engine has three kinds of filters: air, oil and fuel, which are generally called "three filters", plus air conditioning filters, commonly known as four filters. They are responsible for the filtration of lubrication system, combustion system, engine air intake system, and cabin air circulation system.

Kind

Centrifugal oil filter has a rotor sleeve on a shaft, and two nozzles in the opposite direction of spraying, when the oil enters the rotor and comes out of the nozzle, the rotor rotates rapidly, so that the oil in the rotor body is cleaned, and the impurities in the Jane Tsai oil are centrifugally thrown onto the inner wall of the rotor, and the oil from the nozzle flows back to the oil pan.

Centrifugal oil filters are characterized by stable performance, no filter elements that need to be replaced, and can be reused as long as the rotor is regularly dismantled to clean the dirt deposited on the rotor wall. Its life is equivalent to that of an engine. Its disadvantage lies in the complex structure, high and bulky, etc., and has high technical requirements for users.

Full-flow oil filters, such as exchangeable, spin-on, split-flow centrifugal, etc., filter all the oil entering the system. Split flow filters only filter 5%-10% of the oil supplied by the oil pump. Split-flow oil filters are fine filters, which are generally used in combination with full-flow filters.

Most of the low-power engines only use full-flow filters, and the high-power diesel engines mostly use full-flow plus shunt filters.

The air sail filter is about 20,000 kilometers to replace once, if you often run back to a dusty place, you can open the hail can be replaced after 10,000 kilometers, and you can delay it if you often run at high speed, and the time is generally not seen.
