What is the technology of automobile engine construction and maintenance?

Well, do you think you are consulting this major or this technical technology? If it is engine maintenance and overall maintenance major, it is automobile inspection and maintenance major.

Well, if it's a simple mechanical engine, then you mainly learn five major systems, including hydrogen system, lubrication system and fuel injection system. Ah, including our timing gas distribution system and so on. The content is relatively large, mainly to learn the structure of the engine.

Cooling system: generally composed of water tank, water pump, radiator, fan, thermoster, water temperature gauge and water release switch. Car engines adopt two cooling methods, namely air cooling and water cooling. Generally, car engines are mostly water-cooled.

engine oil,That is, the engine lubricating oil can play the role of lubrication and wear reduction, auxiliary cooling, sealing and leakage prevention, rust and corrosion prevention, shock absorption and cushioning and so on. It is known as the "blood" of cars. Oil is composed of two parts: base oil and additives.

Engine maintenance: including engine disassembly, cleaning, inspection, maintenance and assembly technologies. Transmission maintenance: including transmission disassembly, cleaning, inspection, maintenance and assembly and other technologies. Electrical system maintenance: including fault diagnosis, maintenance and replacement of automotive electrical systems and other technologies.

Automobile engine maintenance technology?

Semi-synthetic oil: The replacement cycle of semi-synthetic oil is generally about 8,000-10000 kilometers, and the price and performance are moderate. Mineral oil: This type of oil generally needs to be replaced at about 5,000 kilometers. Try to choose multi-stage oil. Multi-stage oil has a good protective effect on the engine due to its saving, long life and high efficiency.

Learning engine maintenance technology is relatively easy to learn. The main thing is to learn the mechanical part first, and this part should be practiced more. The second is the disassembly and installation part. The electronic control part should listen to the teacher's explanation for corresponding detection and measurement.

If there is a lot of carbon, you should go to the repair shop to remove the carbon. 5. Replace the car's "three filters" on time. Three filters refer to air filters, oil filters and gasoline filters. The third filter plays a role in filtering air, oil and gasoline on the car engine, thus playing a protective role on the engine and improving the efficiency of the engine.

Testing and Maintenance of Automobile Engines Technical Paper I Inspection and Maintenance of Automobile Engines [Abstract] For automobiles, the engine is the core component, which is related to the overall performance of the automobile, which is very important for the composition of the automobile.

To be proficient in automobile repair, you must master the principles of automobiles, including mechanical principles, electrical principles, movement principles and maintenance technology. Due to the large variety of automobiles and complex structures, it is difficult to be fully proficient.

Common faults and maintenance techniques of automobile engines?

The engine compartment odor may also be caused by a large amount of lubricating grease during maintenance, which evaporates with the increase of engine temperature. The exhaust color is abnormal. Whether the car engine is faulty or not is also a little obvious. Analyze the engine failure from the abnormality of the exhaust color.

"Oil into water" and "water into oil" are two faults of different nature. "Oil into water" is a problem with the engine itself, while "water into oil" is mostly caused by engine accessories, and the nature of the fault is different. Solution: You should go to the repair shop for replacement and repair in time.

This article will introduce the common faults of automobile engines and their repair methods to help readers better understand and solve these problems.The engine cannot be started. The engine cannot be started due to battery failure, ignition system failure, oil supply system failure and other reasons.

Fault phenomenon: Turn on the ignition switch, turn the ignition switch to the starting position, and the engine cannot start.

Common faults and maintenance methods on cars Common faults I: What is the reason for excessive gasoline wear? Caused by mechanical factors: car failure leads to a decrease in efficiency. Please go back to the factory for maintenance to confirm that there is no fault. The car engine is worn out; the engine is overhauled.
