Notes on car engine maintenance

Notes on automobile engine maintenance Regular replacement of engine filter and air filter: engine filter and air filter also need to be replaced regularly. The engine filter can block impurities entering the engine, and air filter can block dust and impurities in the air.

The "three filters" of replacing cars on time refer to air filters, oil filters and gasoline filters. The third filter filters the impurities in the air, oil and gasoline of the car engine, protects the engine, and improves the efficiency of the engine, so the filter must be replaced within the specified time.

How to maintain the car engine? The engine maintenance should be done as follows: regular replacement of oil and oil filter, good ventilation of the crankcase, regular cleaning of the fuel system, regular maintenance of the water tank, maintenance and cleaning of the fuel system.This engine needs regular maintenance.

How to maintain the car engine

1. How to maintain the car engine and replace the oil and filter regularly. The quality of lubricating oil of any quality level will change during use. In order to avoid failure, the oil should be changed regularly according to the usage, and the amount of oil should be moderate (generally, the upper limit of the oil gauge is better). Use lubricating oil of appropriate quality grade.

2. Rust and scale will limit the flow of coolant in the cooling system, reduce the heat dissipation effect, causing the engine to overheat, and even cause engine damage. Therefore, the water tank should be cleaned regularly to remove rust and scale in it. Maintenance of three filters Three filters refer to air filters, oil filters and gasoline filters.

3. Clean the water tank regularly.Rust and scale will limit the flow of coolant in the cooling system, reduce heat dissipation, causing the engine to overheat and even cause engine damage. Therefore, the water tank should be cleaned regularly to remove rust and scale in it. Replace the oil and filter element regularly.

4. Only by using qualified lubricating oil can we reduce the wear of engine parts and extend the service life. Therefore, you should pay attention to filling good quality engine oil. Use qualified coolant (antifreeze). Especially in winter, the appropriate coolant should be selected according to the ambient temperature. Clean up the water tank, scale, etc. regularly.

5. Use high-quality engine oil. Oil is an engine lubricating oil, which has the functions of lubricating, cleaning, cooling, sealing, reducing wear and so on. Only the use of qualified lubricants can reduce the wear of engine parts and extend the service life, so we usually pay attention to filling high-quality lubricants.

How to maintain the car engine

Regular maintenance of the water tank. Rust and scaling of the engine tank are the most common problems. Rust and scale will limit the flow of coolant in the cooling system, reduce heat dissipation, cause the engine to overheat, and even cause engine damage.

How to use and maintain the car engine Grinding: that is, running in. This is the basis for extending the service life. Whether it is a new car or a overhauled engine, it must be run-in according to the regulations before it can be put into normal operation.

Keep the crankcase well ventilated. Nowadays, most gasoline engines are equipped with PCV valves (crankcase forced ventilation device), but pollutants in the air will be deposited around the PCV valve, which may block the valve.Therefore, the pollutants around the PCV valve must be removed regularly. Replace the oil and filter element regularly.

Clean the crankcase regularly. During the operation of the engine, the high-pressure non-gas, acid, water, sulfur and nitrogen oxides in the combustion chamber enter the crankcase through the gap between the piston ring and the cylinder wall, and are mixed with the metal powder generated by the wear of the parts to form sludge. Therefore, the crankcase should be cleaned regularly to keep the interior of the engine clean.

How to maintain the car engine? Clean the storage tank regularly. Rust and scale limit the fluidity of the refrigeration liquid in the refrigeration system, reduce the heat dissipation effect, cause the engine to overheat and destroy the car engine. Clean the water tank regularly to remove rust and scale. Change the oil and filter core regularly.

How to maintain the car engine

Regularly replace the oil and oil filter, the crankcase is well ventilated, the fuel system is cleaned regularly, the water tank is regularly maintained, and the fuel system is maintained and cleaned. This engine needs regular maintenance. When driving through some particularly humid or dusty areas, it is also necessary to do some inspection and maintenance of the relevant parts of the engine.

Notes on automobile engine maintenance Regular replacement of engine filter and air filter: engine filter and air filter also need to be replaced regularly. The engine filter can block impurities entering the engine, and air filter can block dust and impurities in the air.

I have to say that the appearance of cars has greatly changed our lives. Today, let's take a look at how to maintain the car engine. In the automobile industry, normal maintenance is roughly divided into (there are no strict regulations, it is called the size of the bag): minor maintenance and major maintenance.But the non-automotive industry may be a little mysterious.

How to maintain a car engine? The engine of a vehicle is equivalent to a human heart. Correct usage and maintenance can extend the life of the engine and maximize its ability. And improper use and maintenance methods will reverse it and affect the performance of the engine.
