What is meant by vehicle three filters

heading_title


Car owners and friends may have heard the word three filters more or less, but for many novice car owners, they may not know what three filters specifically mean. Three filters are a long-established synonym in the industry, representing three commonly used auto parts, namely oil filters, fuel filters, and air filters, which are responsible for the lubrication system, fuel system and engine intake system respectively. Filtration of medium. Since car owners usually need to overhaul or replace these three accessories at the same time when carrying out car maintenance and repairs, a synonym for three filters is formed.

 

One: oil filter

The function of the oil filter is to filter out harmful impurities in the oil. The oil filter, also known as the machine filter, is located in the engine lubrication system. The upstream of the filter is the oil pump, and the downstream is the parts in the engine that need to be lubricated. The machine filter filters out the harmful impurities in the oil from the oil pan, and supplies the clean oil to the crankshaft, connecting rod, camshaft, supercharger, piston ring and other moving pairs, which play the role of lubrication, cooling and cleaning, thereby prolonging the life of these parts.

Suggested replacement cycle: It is generally recommended to replace every 5000 kilometers / 6 months

 

One: Why does the engine never catch fire?

 

      The starting of the engine relies on the current from the battery to drive the spark plug to ignite, so when this problem occurs, there is a good chance that the battery is rusted or dripping. Therefore, in order to avoid this problem, the driver must regularly check whether the battery fluid capacity in the car battery is sufficient, and the cycle is about once a month or two. And check the battery's positive and negative terminal contacts for rust or dirt every year.

Two: fuel filter

 

The function of the fuel filter is to filter out impurities in the fuel. The fuel filter is divided into the carburetor type and the electronic injection type. For the engine using the carburetor, the fuel filter is located on the inlet side of the fuel pump, and the working pressure Smaller, nylon casing is generally used; the fuel filter of the EFI engine is located on the outlet side of the fuel transfer pump, and the working pressure is high, and a metal casing is usually used. The filter element of the fuel filter is mostly made of filter paper, and some also use nylon cloth and polymer materials.

Replacement cycle suggestion: It is generally recommended to replace it every 30,000-40,000 kilometers.

Three: air filter

 

The function of the air filter is to ensure that the air entering the engine is clean. The engine must inhale a large amount of air during operation. If the air is not filtered, the dust suspended in the air will be sucked into the cylinder, which will accelerate the piston group and the cylinder. of wear. The main components of the air filter are the filter element and the casing. The filter element is the main filtering part, which is responsible for the filtration of the gas, which is equivalent to the mask of the car, and the casing is the external structure that provides the necessary protection for the filter element.

Suggested replacement cycle: It is generally recommended to replace it every 10,000 kilometers / 6 months

The life of a car largely depends on its heart, that is, the life of the engine. Overloading, high-speed driving, bad driving habits of starting and stopping, etc., may lead to reduced performance and shortened life of the engine. Dirty and pollution are the most harmful to the performance and life of the engine, and the filter is an important component to avoid dirt and pollution. Therefore, car owners and friends must pay attention to the maintenance of the three filters when maintaining their cars.
