When many car owners are doing car maintenance, they will hear the maintenance staff reporting the vocabulary of maintenance items such as air filter, machine filter, steam filter and air conditioner filter. The names are very similar and it is not easy to remember. People get dizzy when they hear it.
When many car owners are doing car maintenance, they will hear the maintenance staff reporting the vocabulary of maintenance items such as air filter, machine filter, steam filter and air conditioner filter. The names are very similar and it is not easy to remember. People get dizzy when they hear it. In addition, they all have their own different maintenance cycles and features, and their prices are also different, so it is often easy to confuse them together and not know the difference. Next, this article will give some brief introductions to these routine maintenance items, allowing you to get these maintenance tips in 5 minutes:
Air filter (full name air filter)
Maintenance cycle: every 7500-8000 kilometers
The main function of the air filter is to purify the air that enters the engine for combustion reaction with fuel, so as to protect the precious "heart" components such as cylinders and pistons from wear. It is very dangerous for the dust, particles and particulate impurities suspended in the air to directly enter the engine without filtering. In severe cases, it will cause the phenomenon of cylinder pulling between the piston and the cylinder, causing great damage to the engine.
Air filters are generally installed near the air intake of the engine. There are two types of filter paper type and oil bath type. The filter paper type has low cost, high filtration rate and convenient maintenance, and is widely used in all kinds of family cars. It is more convenient to replace the filter paper air filter. A tool such as a screwdriver can help you replace the air filter DIY. When replacing and using, you should try to avoid getting the filter paper wet. The oil bath type is relatively complicated, and it is recommended to replace it with a regular maintenance organization.
Machine filter (full name is oil filter)
Maintenance cycle: replace every 5000 kilometers or random oil maintenance cycle
The machine filter is generally replaced synchronously with the maintenance cycle of the oil, mainly to filter the oil impurities to ensure the normal lubrication function of the engine. During the use of the automobile engine, it is inevitable that there will be impurities such as metal debris, dust, carbon deposits, water vapor, and oil oxide colloids. The oil filter will filter them out and play a cooling role, thereby prolonging the use of oil. life, to ensure the normal operation of the engine. The oil filter is mainly composed of filter paper, sealing ring, backflow suppression valve, overflow valve and other structures. Its replacement requires professional equipment and tools. It is not difficult to replace the oil filter. Conditional riders can also try to replace it themselves. .
Steam filter (full name is gasoline filter)
Maintenance cycle: about every 15,000 kilometers
Gasoline filters are important auto parts that filter fuel impurities, provide clean fuel for the engine, and protect the engine and fuel supply system. During the production, storage and transportation of gasoline, certain impurities such as iron oxide, dust, etc. will inevitably be produced, or the oil quality of some gas stations is poor and contains a large amount of impurities. If it enters the engine and fuel supply system, it may damage the cylinder or cause the fuel injection nozzle to be blocked.
There are mainly two types of gasoline filters: carburetor type and EFI type. They mainly fold filter paper, non-woven fabric and polymer materials around the inner core. The gasoline is filtered through the micropores of the filter element, and then flows out from the central pipe. , so as to filter out impurities and purify. When replacing the gasoline filter, it is necessary to operate according to the manufacturer's guidelines, especially to cool the engine first, release the pressure of the oil supply system, and beware of oil leakage during installation.
Air conditioning filter (full name is air conditioning filter)
Maintenance cycle: every 8000-10000 kilometers
Many people easily confuse the air filter with the air conditioner filter. In fact, the air conditioner filter mainly filters the air entering the car from the outside in the air conditioning system of the car, so that impurities, dust, pollen, and tiny particles in the air are isolated. On the outside, some high-end air conditioner filters can also filter out PM2.5, creating a healthier and hygienic environment for the occupants of the car. Air conditioning filters are generally divided into two categories: ordinary type and activated carbon type. The ordinary type only has filtering materials such as non-woven fabrics, etc., while the activated carbon type uses granular activated carbon in the interlayer to adsorb tiny particles and harmful substances. will be better.
It is relatively simple to replace the air conditioner filter. Most models can find the installation location near the glove box in front of the co-pilot, and can be easily replaced by yourself. The main supply brands in the market are Bosch, MAHLE, MAN and so on. If it is in an environment with strong sand or high humidity, the replacement of the air conditioner filter should be more frequent. Don't wait until the air conditioner in the car is turned on and there is a peculiar smell before knowing to replace it.
summary:
The air filter, gasoline filter and oil filter are all cleaning parts for the engine system, while the air conditioner filter is to ensure the fresh air in the car. Although these "four filters" are all filtering impurities , but their filtering objects and functions are still very different, and their filtering standards are also very different. During maintenance, you must strictly follow the replacement cycle in the car maintenance manual, and you can even replace it in advance according to the environment of the car. In addition, don't be greedy to buy Sanwu products at a small price, the final filtering effect is not up to standard, causing greater losses and troubles!
