Motor oil, gasoline, air, and air conditioning, commonly known as the "four" car don't see their volume is not large, but in the process of car use is be short of one cannot. Oil, gasoline is like human lung, it filters out the impurities of the oil, gas, allows the engine to operate properly. Air, and air conditioning is also a filter, filter without them, it is a good car can go far, it is a good air conditioning has peculiar smell. Carol throttle body, to remind the owner of the car every "grid", conversion, the most expensive is not necessarily the best.

The oil,

Oil's role: as the name implies, the oil's function is to filter the inside of the engine oil, improve its cleanliness and lubrication degree, thus reduce engine wear, to exert the best function.

Working principle: as the blood circulation of the heart, in the oil pump motor oil is also in constant circulation, in the process, often can produce a lot of our unexpected impurities, and this kind of unclean thing we have to oil filter.

Price: domestic economical car, such as changan star, xiali jinbei, etc., the oil price is in commonly used between 8 to 15 yuan. Mid-range car, using the oil price in 15 ~ 35 yuan between; In high-grade car, the matching engine oil, price is in commonly 35 ~ 65 yuan between, Individual scarcity of models on the market, the oil price is 90 yuan. In addition, a deputy factory oil prices generally for 5 ~ 10 yuan, roughly is factory price of a third. But deputy factory of poor quality, the aprons is easy bad, easy to cause leakage, directly affect the operation of the engine, lead to wear and is not recommended.

Recommend replacing time: car for every 5000-10000 km driving change at a time. Carol throttle body recommended oil change every time, should be the oil change. Reason is the old engine oil in the dirt, can lower the viscosity of the new engine oil and cleanliness, influence the oil circulation speed, also can damage the engine.

gasoline

Gasoline: filter tank to the gasoline engine combustion chamber.

Working mechanism: usually there are all kinds of impurities in gasoline, fuel tank use for a long time may precipitate a dirt, these reasons will affect the quality of gasoline. Gasoline is used to filter the impurities, the petrol tank after gasoline filter to reach the combustion chamber of engine, its clean purity can get effective guarantee.

Price: the material of gasoline for car, most economic models of gasoline price in 50-100 yuan between, a handful of special models of gasoline prices in 100-100 yuan between. High-grade car gasoline price in 100 yuan of above, the overall difference not by much. Some generic gasoline or a less known and inferior brand, easily lead to leak, may cause spontaneous combustion and explosion, for body, person are quite dangerous, is not recommended.

Recommend replacing time: the car every 20000 km or so.

The air,

Role: air, in the inlet position of the engine, it can effectively filter dust impurities in the air, make the air into the combustion chamber purity greatly increased, to ensure that the fuel combustion.

Working mechanism: air cell is composed of paper screen, look be like simple structure, role is to be reckoned with. The malfunction of the air, can lead to combustion of gasoline is not sufficient, and lack of engine power, and pollution of the throttle body, lead to unstable idle speed, the symptom such as abnormal engine jitter.

Price: the general models of air in 50-100 yuan between, price is a few special vehicles, such as jaguar, Mercedes, BMW yuan air price is in 100 yuan of above.

Deputy factory prices generally positive factory parts price of 1/3 ~ 1/4, up to 20 or 30 yuan.

Recommend replacing time: the car every 20000 km or so.

Air conditioning,

Air conditioning's role: with air like, air conditioning, is the function of filtering impurities such as dust particles in the air, provide clean air for the automotive air conditioning.

Working principle: in addition to a few old models, currently on the market, a new model of air conditioning, mostly with activated carbon, air cleaner functions are improved greatly. Long time no replacement of air conditioning, can cause clogging the inlets, lead to the cooling air volume less, slow cooling, also can produce peculiar smell.

Price: basic in dozens of yuan. Recommended to choose air conditioning with activated carbon, the price is without activated carbon in the air conditioning only a few higher.

Recommend replacing time: the car every 20000 km or so.

To 4 s shop outfit these fittings are quality guaranteed, but the price is very high also, and such as oil, and gasoline quality is cannot careless, how can you do accessories cheap and good? Carol throttle body Suggestions, in order to ensure the quality of purchased parts, car owners can take time to professional purchasing regular brand accessories, auto parts market is not necessarily a factory or imported parts, but it must be the regular brand, so procurement, both to ensure the quality, the price is cheap. Placed buy some more spare in the car, make regular replacement or professional auto inn concentration change, not a lot of benefits.

Carol throttle body using alternate remind matters needing attention

1, gasoline and oil replacement after installation, should pay attention to the sealing interface, wary of oil leakage phenomenon;

2, for the air, and air conditioning, to ensure the change after the sealing of the whole;

3, take good care of gasoline, try to use car manufacturer supporting grade gasoline.
