Commonly known as oil grid, petrol grid, air grid and air-conditioning gridcar"Four grids" don't look at their size, but they are indispensable in the process of using the car. The oil grid and gasoline grid are like human lungs. They filter out the impurities in the oil and gasoline, so that the engine can run normally. The air grid and the air conditioning grid are also a filter. Without their filtration, even the best car can't go. No matter how far away, even the best air conditioner has a peculiar smell. Lin Weihua, a senior technician of Huang Poluo, reminds car owners to pay attention to every "shape" of the car. When disassembling and replacing, the most expensive but not necessarily the best.
Oil grid
The function of the oil grid: As the name suggests, the function of the oil grid is to filter the oil in the engine to improve its cleanliness and lubrication, thereby reducing the wear of the engine and making it perform its best function.
How it works: Just like the blood circulation system of the heart, the oil in the oil pump is constantly circulating. In this process, many unexpected impurities are often produced, and such unclean substances need to be filtered by the oil grid.
Price: Domestically-made economy cars, such as Changan Star, Xiali, Jinbei, etc., generally use oil at a price of 8-15 yuan; mid-range cars, use oil at a price of 15-35 yuan; mid-to-high-end cars , The price of the matching oil grid is generally between 35 to 65 yuan; the price of the oil grid for individual models that are scarce on the market is about 90 yuan. In addition, the price of the oil grid for auxiliary parts is generally 5-10 yuan, which is roughly 1/3 of the price of the original parts. However, the quality of the auxiliary parts is poor, and the rubber ring is easy to break, and it is easy to cause oil leakage, which directly affects the operation of the engine and cau

However, the quality of the auxiliary parts is poor, and the rubber ring is easy to break, and it is easy to cause oil leakage, which directly affects the operation of the engine and causes wear. It is not recommended to use.
Suggested replacement time: The car should be replaced every 5000-10000 kilometers. Experts suggest that every time the oil is changed, the oil grid should be changed. The reason is that the dirt in the old oil grid will reduce the viscosity and cleanliness of the new oil, affect the oil circulation speed, and also damage the engine.
Petrol grid
Gasoline grid function: filtrationtankGasoline to the combustion chamber of the engine.
Working mechanism: There are various impurities in general gasoline, and a certain amount of dirt will be deposited in the fuel tank for a long time. The above reasons will affect the quality of gasoline. The function of the gasoline grid is to filter the above-mentioned impurities. The gasoline in the fuel tank is filtered by the gasoline grid to reach the combustion chamber of the engine, and its clean purity can be effectively guaranteed.
Price: The material of the gasoline grid varies from car to car. The gasoline grid price of most economic models is between 50 and 100 yuan, and the gasoline grid price of a few special models is between 100 and 200 yuan. The gasoline price of mid-to-high-end cars is above 100 yuan, and the overall difference is not much. Some sub-factory parts or miscellaneous brand petrol grids are likely to cause oil leakage, spontaneous combustion or even explosion, which are quite dangerous to the car body and human body, so it is not recommended to use it.
Suggested replacement time: every 20,000 kilometers of the car.
Air grid
Air grid function: The air grid is installed at the intake port of the engine. It can effectively filter the dust and impurities in the air and greatly increase the purity of the air entering the combustion chamber, thereby ensuring sufficient fuel combustion.
Working mechanism: The air grid is composed of a paper filter, which seems to be simple in structure, but its function should not be underestimated.Failure of the air grid will result in insufficient gasoline combustion, insufficient engine power, and pollutionThrottleIt causes symptoms such as unstable idling and abnormal engine shaking.
Price: The air grid price of general models is between 50-100 yuan, a few special models, such as Jaguar,Benz,BMWThe air grid price of Yuan models is more than 100 Yuan. The price of sub-factory parts is generally 1/3 to 1/4 of the price of the original parts, up to 20 to 30 yuan.
