What are several items that a car must maintain and how often?

In recent years, with the rapid economic development in China, people's lives have become more and more affluent, so it is not difficult to buy a car. However, buying a car is easier than maintaining it. Many people think they know nothing about cars. When they go to 4S stores for maintenance, people say that they are them and they don't know what they are doing. Today, Bian Xiao will tell you what needs to be done in daily maintenance and which projects can have a long period.

First, the second filter of engine oil, also known as engine lubricating oil, can play the role of lubrication and wear reduction, auxiliary cooling, sealing and leakage prevention, rust prevention and corrosion prevention, and shock absorption and buffering the engine. Known as the "blood" of the car. With the increase of engine working time, engine oil is polluted due to high temperature oxidation, mechanical parts wear and fuel vapor corrosion and other factors. And there will be some consumption. So be sure to replace it every 5000 kilometers.

Second, cleaning the throttle throttle is like a human throat. It is connected to the air filter and the engine block to control the gas flow into the engine cylinder. Its position is very critical. If the throttle has too much carbon deposit, it will directly lead to less intake air, unstable idle speed and engine jitter. Because the ratio of gasoline to air is incorrect, it will lead to incomplete combustion and aggravate the production of carbon deposits in other parts. So the throttle must be cleaned every 15000 km.

3. Inlet Inlet Inlet Inlet The inlet and passage of air required by the jet engine. The intake port not only provides a certain amount of air for the engine, but also ensures the normal operation of the compressor and combustion chamber. The reason for carbon deposition at the air inlet is also very simple. When the engine is turned off, the intake valves of some cylinders cannot be completely closed, and some unburned fuel is constantly evaporated and oxidized, which will produce some soft black carbon deposits in the intake pipe, especially behind the throttle. On the one hand, these carbon deposits will make the pipe wall of the intake pipe rough, and the intake will produce eddy currents in these rough places, which will affect the intake effect and the quality of the mixture. So clean it every 20 thousand kilometers.

4. Nozzle Nozzle is an important part of fuel, and the fuel is sprayed out at high speed through the annular gap between the pin at the head of the needle valve and the nozzle hole, forming mist, which is beneficial to full combustion. If there is carbon deposit in the nozzle, a new type of spray may appear, which will affect the atomization effect and cause fuel consumption. So you will feel that fuel consumption will increase. And it will lack motivation. So it is recommended that every 30 thousand kilometers. To clean the fuel injectors.

Verb (abbreviation of verb) spark plug The function of spark plug is to ignite. When the cylinder runs to the top dead center, gasoline can be ignited by spark plugs to generate energy. Therefore, the stronger the ignition ability of the spark plug, the better. Many old drivers don't change spark plugs for a long time, and they don't change them when they reach the mileage, thinking that they can use them if they are not broken. In fact, this idea is wrong. Even if the spark plug is not broken, the power and fuel consumption will be affected after the ignition ability drops, but it will drop a little every day and change slowly. I just didn't realize. It is recommended to replace it every 40,000 kilometers.
