What are the items of engine maintenance

The main common maintenance items of the engine are: oil replacement, cleaning the throttle valve, replacement of spark plugs, combustion chamber carbon cleaning, fuel injector carbonization cleaning, cleaning or replacement of fuel injector, replacement of antifreeze, etc. .

Air intake system: clean and replace the air filter, clean the throttle valve, replace the turbocharger, and replace the intercooler in the turbocharger system. Fuel system: replace the fuel filter, gasoline pump, clean the fuel injector, and the correction pump.

Regularly change the oil: The oil is the lubricant of the engine, which can lubricate, clean, cool, seal, reduce wear and other roles on the engine, and is also the "blood" of the engine. Failure to replace the oil for a long time will lead to serious wear of engine parts and reduce the service life of the engine.The manufacturer recommends replacing it every 5,000 or 10,000 kilometers.

Engine overhaul mainly includes the replacement of valves, pistons, cylinder liners, boring cylinders, grinding shafts, etc. According to the standards of general 4S stores, 4 sets of accessories need to be replaced, namely piston, piston ring, valve, valve oil seal, valve duct, crankshaft bushing, connecting rod bushing, timing belt, tension wheel.

Maintenance of car engines. Car engines need regular maintenance. When driving through some particularly humid or dusty areas, you should also do some inspection and maintenance of the relevant parts of the engine. Replace the oil and oil filter regularly.

How is the best way to maintain the vehicle engine

1. Use good quality engine oil. Engine oil, that is, the lubricating oil of the engine, can play the role of lubricating, cleaning, cooling, sealing, wear reduction and so on. Only the use of qualified lubricating oil can reduce the wear of engine parts and extend the service life. Therefore, you should pay attention to filling good quality engine oil.

2. Maintain enough oil, water and air, and do a good job in engine maintenance, so that the engine is always in good condition.Keep the oil, water, air and engine clean. If the fuel is impure, it will affect the matching parts; the cooling water is impure will hinder the heat dissipation of the engine, etc.

3. Brake fluid. From the name, this is more critical. In general, our brake fluid is replaced every 2 years or 60,000 kilometers. Although the brake fluid is not completely lost in the case of leakage, the car will not completely lose braking power, but if it is not replaced for a long time, brake weakness may occur. Even the brakes fail intermittently.

4. How to maintain the car engine and remove 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.

Maintenance skills of automobile engines

1. Regular cleaning of engine carbon. In the process of long-term driving, the power system is easy to produce carbon accumulation, which is also a very common problem. The problem of carbon accumulation often occurs during the festival. The valve, air intake system and other positions.

2. Repair the fuel supply system: If it is found that the fuel consumption has increased, accompanied by engine shaking, power degradation and other problems, it may be caused by the failure of the fuel supply system. At this time, it is necessary to check the oil supply system, determine the cause of the failure and repair it in time. Engine oil leakage Engine oil leakage may cause vehicles to pollute the environment, damage the engine and other problems.

3. Engine common fault maintenance strategy Control lubricating oil consumption The normal operation of the engine inevitably consumes a certain amount of lubricating oil.Abnormal lubricating oil consumption often corresponds to some kind of engine failure.

How about car repair

It's faster to learn auto repair, and it's not very difficult to learn. As long as you practice more and ask more questions, you can find a professional auto repair school, learn a skill, and choose according to your own situation. It's also good to open a machine repair shop.

At present, the volume of traditional fuel vehicles is still very large, and learning car maintenance can well meet the needs of current maintenance positions. Learning new energy technology will be good for the future. It is suggested that everyone should learn together, maintenance + new energy, learn to deal with current employment and future, and find a good job.

Secondly, the salary in the automobile maintenance industry is relatively high.Because car maintenance requires certain professional knowledge and skills, people in this industry can usually get a high salary. Especially in some large car repair companies or high-end car repair shops, the salary level is even more considerable.

Common faults and maintenance methods of automobile engines.

If there is a lot of coolant, the engine thermosator and fan radiator faults should be checked. The problem of engine overheating requires car drivers to master basic common sense and maintenance methods. The engine should be regularly maintained and inspected.

(3) Eliminate the special smell generated by the engine. During the use of the vehicle, if you find a pungent smell or burning smell in the engine compartment, you should stop immediately and checkCheck whether the lines around the engine have been softened or charred, and repair the charred or short-circuited lines in time to avoid larger safety accidents.

Insufficient fuel supply: If the fuel supply in the mixed gas is insufficient, it will cause the engine to burst. At this time, it is necessary to check whether the fuel pump and fuel injector are working normally. Ignition system failure: If the ignition system fails, it will cause the mixture to burn itself at the wrong time, resulting in a burst of the cylinder. At this time, it is necessary to check whether the components in the ignition system are normal.

[Automobile Maintenance] Common faults and maintenance knowledge of cars. Small problems of vehicles can be repaired by yourself. Cars are composed of thousands of parts, and it is not known which accessory will have problems one day and cause car failures.
