What is car engine repair and maintenance?

1. Regularly use BG540 (strong and efficient water tank cleaning agent) to clean the water tank and remove rust and scale in it, which can not only ensure the normal operation of the engine, but also extend the overall life of the water tank and the engine. Maintenance and cleaning of the fuel system. Because the fuel distribution system of the car is very precise, it cannot be disassembled at will.

2. Automobile engine warrantyMaintenance mainly includes the cleaning and lubrication of the engine. In addition, it also includes the completeness inspection of the working performance of the engine and the physical properties of the engine, such as checking whether the parts of the engine are deformed and faulty, and whether the fastness is intact, etc. In addition, it is necessary to supplement the fuel, cooling water and other liquids of the engine and Steps such as replacement.

3. Regular inspection, addition and replacement of oil is also one of the contents of engine maintenance. Engine water tank, motor, spark plugs Regularly check and replace spark plugs. If the engine power drops, the spark plug may be one of the reasons and needs to be repaired.

4. The engine is the heart of the car, as well as the main assembly and power source of the car. At the same time, the structure of the car engine is very complex. In order for the engine to work in a relatively good condition for a long time, it is necessary to pay great attention to the use and maintenance.Next, I will introduce the knowledge of car engine repair and maintenance to you. Let's take a look.

5. What does car repair and maintenance include? Car oil replacement. Oil is the most important lubricant for car engines. Regular oil replacement can ensure the smooth operation of the engine and prolong the service life of the engine. Change the oil every 5,000 kilometers or 6 months.

What aspects should be checked and repaired if the car engine is broken?

Coolant: The coolant is used to ensure the normal operation of the engine. It is necessary to regularly check whether the coolant level is at the standard value, and regularly check whether the coolant pot is leaking. On average, the coolant needs to be replaced once a year of driving.

In this method, employees should use hardware equipment to detect various faulty parts of the engine, such as circuit voltage and gear fitting, etc.

If the engine fails, you should park on the side or drive to the nearest service area, observe the engine status self-check light, observe whether the engine coolant temperature is too high, check whether the engine lacks oil, and observe whether the engine is running smoothly. If the above situation exists, you need to go to the nearest auto repair shop. Carry out maintenance.

Causes and overhaul methods of automobile engine oil burning

Abnormal wear: causes of abnormal wear There is early wear caused by product quality and improper use. If your car burns oil during the warranty period, please contact the manufacturer's four S store in time to negotiate maintenance or replace the engine.

The reasons for burning engine oil are as follows: Poor valve sealing: The valve is to prevent oil from leaking into the combustion chamber, but with the increase of the service life, wear and aging will occur, making the valve sealing poor, so that the oil is easy to enter the combustion chamber.

Why do cars that burn engine oil? When doing non-destructive repair of engine oil burning, you must check the basic situation of the car.Because although most of the oil burning is caused by piston ring jamming, there are also many factors that are superimposed.
