Oil filter, petrol prices, air cell and air-conditioning lattice commonly known as thecar "four case" don't look is not very large volume of them, but in the use of vehicles is indispensable. Oil filter, petrol prices are like human lung, it filters outthe impurity oil, gasoline, so that the engine can run normally; air and air-conditioning lattice is a lattice filter, the lack of their filtration, again good car won't go far, again good air conditioning also has peculiar smell. Cairo solar term door body of owners, to attach importance to each "tick" car, replacement, the most expensive is not necessarily the best.

Air cell

Air: air cell arranged in lattice effect of air intake of the engine, which can effectively filter the impurities of dust in the air, so that the purity of the air entering the combustion chamber is greatly increased, thereby ensuring the full combustion of the fuel oil.

Working mechanism: air lattice by paper filter screen, seemingly simple structure,but the role can not be underestimated. Air grid fault occurs, will lead to the combustion of gasoline is not sufficient, the power of the engine, and the pollution of solar term door body, resulting in unstable idle speed, engine jitter abnormalities.

The proposed replacement car every time: driving for about 20000 kilometers.

Air-conditioning lattice

Effect: air-conditioning lattice with lattice like air, air-conditioning lattice's role is tofilter the air of dust particles and other impurities, providing clean air for automobile air conditioner.

Working mechanism: except for a few older models, currently on the market, air-conditioning lattice new models are mostly with activated carbon, air cleaningfunction has been greatly improved. Long time not to replace the air-conditioning lattice, will cause the air inlet blocked seriously, resulting in cold air cooling less,slow, will produce peculiar smell.

Price: basically in dozens of yuan. Cairo suggested that the owner of the throttle body selection of air-conditioning lattice with activated carbon, air conditioning casethe price is not only higher with activated carbon.

The proposed replacement time: car each running 20000 kilometers.

Gasoline prices

Gasoline prices role: filter tank to the engine combustion chambers of gasoline.

The working mechanism of the throttle body: Carol said various impurities existgenerally in gasoline and fuel tank used for a long time will precipitate some dirt,the above reasons will affect the quality of gasoline. Gasoline prices role is to filterthe impurities, petrol tank after gasoline lattice filter to the combustion chamber of the engine, its clean purity can be protected effectively.

Price: the price of petrol material varies by car, most economic models of gasoline prices price in the 50-100 yuan between, a few special vehicle gasoline prices in the price between 100-200 yuan. In high-end car petrol prices price is in 100 yuan of above, the overall difference between the amplitude. Some of the Deputy plant parts or inferior gasoline prices, easily lead to leakage, may cause spontaneous combustion or explosion, for the body, people are quite dangerous, does not recommend the use of.

The proposed replacement time: car each running 20000 kilometers.

Oil filter

Oil filter effect: as the name suggests, oil filter function is the engine oil filter,improve the cleanliness and lubrication, thereby reducing the abrasion of the engine, to play the best function.

Working mechanism: like the blood circulatory system of the heart, in the oil pumpof the oil is in a continuous loop, in this process, tend to produce many unexpectedimpurities, and this kind of unclean things need oil lattice filter.

Price: domestic economy car, such as the star of Changan, Xiali Jinbei, using oilprice is in commonly 8 - 15 yuan between; intermediate car, the use of oil prices in 15 - 35 yuan between; in high-grade car, its supporting oil filter the general price of 35 - 65 yuan between; individual market dilute the lack of models, the price of 90yuan oil filter. In addition, the Deputy plant parts oil grid prices generally 5 - 10yuan, approximately are plant parts price 1/3. But the poor quality of the Deputy plant parts, the rubber ring is easy to be damaged, easily lead to leakage, directly affects the engine operation, resulting in wear and tear, does not recommend the use of.

The proposed replacement time: car every travel 5000-10000 km about a replacement. Cairo throttle body every oil change, should replace the oil lattice.The reason is that the old oil in the lattice of dirt, will reduce the new oil viscosity and cleanliness, affect the rate of oil circulation, also can damage the engine.
