What are the precautions for automobile engine maintenance

1. Use fuel that meets the requirements. The quality of fuel has a great influence on the combustion of the engine. Inferior gasoline will produce a lot of carbon deposits and glue deposits in the combustion chamber, injector, intake port and valve, which will make the engine unstable at idle speed and difficult to accelerate.

2. It is necessary to preheat the engine when it is started in a cold state. At normal working temperature, the running resistance, wear and working stability between parts of the engine are the best, so preheating is necessary.

3. In the process of driving the vehicle, pay attention to the relevant instructions on the instrument, and always observe the prompts of the water thermometer, oil lamp and charging indicator lamp. If any undesirable phenomenon is found, handle it immediately.

4. Try to keep the engine speed below the red scale of the tachometer when driving, so as to avoid overloading the engine. Vehicles with manual gears should not be delayed as much as possible.

5. Start the engine in a quiet state, let the engine idle and accelerate, and listen to whether the sound of the engine is normal. The normal engine running sound should be low and regular. If there is a sharp sound, please go to the repair shop for diagnosis immediately to avoid further damage caused by the fault.

6. refuel when the fuel filling amount in the fuel tank is kept as low as 1/3, so as to make the gasoline pump in the fuel tank radiate heat well and ensure the gasoline pump has a long enough life.

7. Maintain the engine regularly, maintain the engine according to the mileage on time, and select the appropriate engine oil. Keep the coolant clean, so that the engine has good heat dissipation. Regularly clean the oil and gas circuits of the engine. Ensure that the engine has smooth oil intake and air intake channels.
