The so-called "four compartments" of a motor vehicle include the engine oil compartment、Gasoline grid、Air conditioning grid、Air grid，Don’t underestimate them，An important role in the operation of motor vehicles。

If you compare them to human organs，Just like human lungs or heart，is an indispensable part，Oil compartment、Gasoline grids are like human lungs，It can filter oil、Substances in gasoline，Ensure the motor can operate normally；The air grid and air conditioning grid are also equivalent to filters，Without their filtering effect，No matter how good a motor vehicle is, it cannot operate normally，No matter how good the air conditioner is, it will also blow out odor，Next, let’s learn about the four grids of motor vehicles with the editor。

Let’s talk about the oil grid first，When the engine oil circulates back and forth, a lot of debris Seabetwill appear，It will filter them out through the oil filter，Thus improving the purity of engine oil，Reduce engine wear，It works just like the human heart，Ensure blood system circulation

When the oil in the oil pump is circulating back and forth，There are usually many clutter that we cannot predict，These debris need to be filtered through the oil grid。

When changing the oil during daily car maintenance, you must also replace the oil filter，In addition，Impurities in the machine filter and contaminated engine oil will cause pollution to the newly replaced engine oil，Shorten the use time of new engine oil。

Gasoline fuel ensures normal engine operation

The next is the gasoline grid,The role of the gasoline filter is to ensure the purity of motor fuel，Filter out the moisture and impurities in the gasoline，The purity of gasoline itself is very high，Even if there are some debris in the fuel tank，Steam filter can also effectively filter out，The replacement time of steam filter is generally recommended to be 20,000 kilometers or 30,000 kilometers is also common。

Everyone knows，The motor is the core of the car，Small debris can damage it，Then you need gas grid，The general recommendation for gasoline filter replacement time is nearly 10,000 kilometers，Its main function is to filter out impurities in gasoline，In fact, the function of the filter is to remove the air、Oil、Filter out dust and impurities in fuel and coolant，Keeps the engine from being polluted，To protect the motor operation。

The application environment of engine oil is very harsh，The debris produced when burning gasoline will pollute the engine oil，Oil that has been used for a long time will oxidize、Deterioration，seabet loginAnd it will evaporate and decrease，Therefore, the lubrication and protection function of the motor is lost，causing the engine to break。(Note: The air grid needs to be replaced every 2 maintenances、Gasoline grid、Air conditioning grid、Spark Plug，This is the manufacturer’s maintenance recommendation for B series engines)。

Air conditioning grid and air grid ensure clean air

An air conditioner again, usually called cabin filter，The function of the air conditioning grid is to filter out the air entering the cabin from the outside，Ensure clean indoor air，Usually filters refer to debris brought in the air，Fine particles、Pollen、fine、Exhaust gas pollution and dust, etc.。The reason why the air conditioning filter is clogged is dust in the air。

The editor would like to remind all car friends，Pay attention to every aspect of the car，Choose the appropriate one when replacing，Don’t just pursue price，The most expensive is not necessarily the most suitable，If you go to the 4S store to replace these accessories，Quality should be guaranteed，But the price/performance ratio is low，The quality of the four grids is not good at all。

How to make accessories cost-effective？The answer is that car enthusiasts can take the time to go to the professional auto parts market to buy some regular brand accessories，It does not have to be imported parts or original parts，But it must be a regular brand，In this way, the quality can be guaranteed，It can also be cost-effective。

Car enthusiasts can replace it regularly according to their own situation or go to a professional car repair shop to replace it. It is feasible，If you replace it yourself，Pay special attention seabet appto the sealing of the interface。
