Is a large-scale Sino-foreign joint venture established at the end of 20 _ _, with BMW's high standards, high quality requirements and customer satisfaction as its purpose. Now it has become a high-standard 4S shop integrating automobile trade, maintenance service, parts sales and information supply. It has been awarded the honorary titles of "Advanced Unit of Quality Service", "Star Enterprise", "Trustworthy Unit of Quality" and "Civilized Demonstration Window" by the management department of automobile maintenance industry and the technical quality supervision department of the government for many times. It is a key enterprise in Yulin automobile maintenance and sales industry and a provincial-level designated unit for automobile maintenance.

Internship purpose:

Familiar with the daily maintenance of cars; Check and change the oil and oil.

② Four-wheel maintenance

Seven internship content:

(1) Daily maintenance of automobiles

Daily car maintenance is very important. To buy a new car, you must first know how to maintain it.

Several tasks to be done in automobile maintenance;

Clean the appearance of the car, and check whether the door and window glass, wiper, indoor mirror, rearview mirror, door lock and lifter handle are complete and effective. Check whether the water quantity of the radiator, the oil quantity of the crankcase, the oil storage quantity of the oil tank and the electrolyte level in the battery meet the requirements. Check whether the horn and lighting are complete and effective, and whether the installation is firm. Check whether the connecting parts of the steering mechanism are loose and firmly installed. Check whether the tire pressure is sufficient and remove impurities between the tire and the wheel track. Check whether the tire nut, axle bolt, leaf spring riding bolt and T-bolt are firm and reliable. After starting the engine, check whether the instrument works normally and listen to the engine for abnormal sounds. Check whether the vehicle has "four leaks" such as water leakage, oil leakage, air leakage and electric leakage. Check whether the traction device works reliably.

Five steps to change automobile oil:

The main functions of engine oil are lubrication, cooling, sealing, cleaning, rust prevention and corrosion prevention? If there is no oil, the heart of the car will not work normally. Use mineral oil, usually change the oil every kilometer. The correct oil change standard is calculated by "engine running time".

1. Correct selection of quality grade and viscosity grade of lubricating oil.

2. Select high-quality oil filter elements produced by regular manufacturers to prevent oil blockage, insufficient pressure or poor filtering effect caused by filter element quality problems from affecting the lubrication effect.

3. When changing oil, when the engine is at normal working temperature, turn off the engine, unscrew the filler cap, remove the oil drain screw to discharge the old oil, and unscrew the old filter with special tools. If conditions permit, the engine should be cleaned to thoroughly remove the sludge and colloid in the engine.

4. When replacing a new filter element, check whether the filter element sealing ring is intact, deformed or damaged.

Damaged ones should be replaced in time. When assembling the filter element, the filter element should be filled with clean lubricating oil, and the sealing ring should be coated with lubricating oil to prevent damage during installation.

5. After installing the oil filter element, tighten the oil drain screw and inject a certain amount of new lubricating oil into the engine crankcase as required. The dipstick and oil level should be between the upper line and the lower line. Install the dipstick and tighten the filler cap, and start the engine to rotate quickly for a few minutes to check whether the oil pressure is normal and whether there is oil leakage. If there is any abnormality, stop the machine in time to check and eliminate it. Never add too much or too little engine oil. Excessive engine oil will lead to excessive consumption of lubricating oil, increased engine running resistance and increased fuel consumption. Low oil pressure will lead to low lubrication and poor lubrication.

(2) Daily maintenance of automobiles

1. Air pressure check

The tire pressure should be inflated according to the regulations of the car factory, and the tire pressure should be checked frequently at ordinary times. Too high or too low air pressure will lead to abnormal tire wear. Excessive air pressure will cause excessive wear in the middle of the tire; Too low air pressure will lead to excessive wear on both sides of the tire. In addition, the incorrect tire pressure will also cause faults such as reduced ride comfort, heavy steering and brake deviation.

2. Crack and pattern inspection

Regularly check the tire surface for cracks, deformation and other defects. If yes, replace the tire in time. Check the tread depth of the tire. If the tread wear reaches the wear limit (the tread depth of cars and trailers shall not be less than1.6mm; The tread depth of the steering wheel of other vehicles shall not be less than 3.2 mm, and the tread depth of other tires shall not be less than 1.6 mm), which must be replaced.

3. Time limit check

Tires that have been used for more than 6 years need to be replaced regardless of whether they are in good condition or not. Execute the second dimension.

When the maintenance or driving mileage reaches 10000km, the tires shall be cross-transposed according to the regulations, so as to make all tires wear evenly and prolong the service life of the tires as much as possible.

4. Tire replacement

When installing tires, tires with the same specifications, sizes, patterns and cord layers should be assembled on the same shaft. When replacing tires, it is best to replace all tires at the same time, at least in pairs. The steering wheel (front wheel) must be replaced with new tires, and worn old tires must never be replaced.

5. Vehicle parking

When the vehicle is parked, it is also necessary to protect the tires and avoid parking the tires on the road with thick, sharp or sharp obstacles. In addition, it should be avoided to park with petroleum products, acids and other substances that affect rubber deterioration.

6. Treatment of fever

When driving in summer or at high speed, the tire is easy to overheat and increase the air pressure. Stop cooling at this time, and do not deflate or splash water to cool down.

7. Check the tire tread

Regularly check whether the tire tread is punctured and whether there are stones stuck between the two wheels. Remove the stones embedded in the tire. If there are small holes in the tread, fill them with raw rubber to prevent sand and soil from invading the cord layer and causing gaps.

Generally speaking, I have successfully completed this internship, which will play an important role in my future work.

Eight practical conclusions

The one-month internship soon ended, but in this short month, I learned something that I couldn't learn in school. College students' internship is college life.

In the transitional stage of social work, there is a great difference between school and society. Therefore, internship is particularly important. Internship in BMW Yulin, go to work on time every day, get off work on time, and eat in the staff canteen. Although I seldom do anything, I still feel the working atmosphere, so I should find a good direction for my internship so that I won't take detours in the future. After all, I have less opportunities to get in touch with society at school, and I don't know much about society, and I am professional and practical.

Through this period of internship, I have deep feelings. Practicing in BMW Yulin, most of them are return visits, and the problems encountered in them are solved by learning from the master. This internship has cultivated our practical ability, and I have a macro grasp of what this major may involve in the future. It is because I have a better understanding of the automobile industry and know that my knowledge is far from enough, and I still need to learn. In order to be better qualified for the job in the future and understand the general situation of the development of the automobile industry in China and even the world, we have also passed this internship, so that we can communicate better, learn to get along with others and achieve unprecedented professional unity. Therefore, this internship is of great significance, and our tasks and responsibilities are not trivial. Judging from the results of our internship, we have indeed achieved certain goals and basically completed the task smoothly.

Summary of automobile repair practice in technical secondary school II

On July 10, 20 _ _, a special day, I started a 40-day automobile maintenance internship. During these 40 days, I mainly studied the related knowledge of automobile secondary maintenance and automobile maintenance business. Secondary maintenance is mainly used to inspect and adjust the safety components such as steering knuckle, steering rocker arm, brake shoe and suspension that are easy to wear or deform after a certain period of use, as well as vehicle maintenance operations such as disassembling and inspecting tires, transposing tires, inspecting and adjusting engine working conditions and exhaust pollution control devices. , and the maintenance enterprise is responsible for the implementation.

As a means of transportation to carry passengers or goods, cars are also consumables. In order to maintain its excellent performance, it is generally required to enter the factory for secondary maintenance every 7500- 10000 km. The acceptance criteria for secondary maintenance of automobiles are mainly as follows:

1. The engine should be easy to start, run smoothly, exhaust normally (refers to the exhaust gas reaching the standard), the water temperature and oil pressure meet the requirements, the speed is stable, there is no abnormal sound, the belt is moderately tight, and there are no four leaks (water, oil, electricity and gas).

2. The directional free travel and toe-in meet the requirements, and the steering is light, flexible and reliable. When driving, the front wheel has no left-right swing and deviation.

3. The free stroke of the clutch meets the requirements, with convenient operation, complete separation, stable and reliable combination, no abnormal sound and no oil leakage in the hydraulic system.

4. Gearbox, drive axle, universal joint (or half shaft) transmission device, etc. Good lubrication, reliable connection, no abnormal sound and overheating, no tripping, flexible gear shifting and no oil leakage.

5. The free travel and intermittent braking of the brake pedal meet the requirements, the driving and parking brakes are good, there is no deviation and delay during braking, the inertia proportional valve works normally and there is no oil leakage.

6. The tire pressure is normal (different models have different high and low air pressure standards).

7. Cantilever and shock absorber are fixed reliably and function normally, and the temperature of hub bearing is not too high after driving.

8. The generators, starters, signal lights, meters, signal lights, buttons, switches and ancillary equipment are complete and can work normally.

9. Fill all lubricating points of the vehicle with lubricating oil. 10, clean the whole vehicle. As long as the maintenance manufacturer completes the above 10 secondary maintenance operation, it can ensure the technical condition of the vehicle and let the owner pick up the car with confidence.

The above is my perceptual and rational understanding of secondary maintenance during my 40-day study in the garage. Of course, I only have a short 40-day garage internship, and I only know some superficial knowledge about the secondary maintenance of automobiles. When I first arrived at the repair shop and started to make a second-level maintenance order, I occasionally made some small mistakes. For example, when filling out the form, the maintenance personnel of the big car and the maintenance personnel of the small car are occasionally confused. Once such an error occurs, the wrong report will be invalid and must be reprinted, which will undoubtedly affect work efficiency. From then on, I immediately realized that in the face of tedious work, I must maintain a rigorous and serious work attitude. This can make people make fewer mistakes and fewer mistakes.

In just 40 days, I went from simply doing the secondary maintenance report to being able to complete the secondary maintenance report of various vehicles independently and quickly. Although this is only a small step, it is of special significance to my life. It marks my gradual growth in a strange industry, and it is also a color note written in the process of my life growth. As a professional automobile maintenance teacher, in this high-speed development and challenging and competitive society, I have no other advantages except to make up for my own shortcomings with my diligence. "Heaven rewards diligence", I believe that in this industry, it will gradually grow, go further and further, and do better and better.

Finally, I thank the leaders of the company for their concern and teaching, the leaders of the group company for providing me with such a learning platform, and the teachers and colleagues for their help and guidance in my work.

During the three months from _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _

Dongfeng Nissan _ _ _ _ franchise store is the first-class maintenance equipment directly provided by Dongfeng Nissan, such as elevator, tire dynamic balancer, body straightening frame, painting room, four-wheel alignment instrument, etc. It also has advanced imported testing instruments, such as Nissan computer tester, ignition tester, snow maker and so on. And a computer network for maintaining services. Spacious and tidy business reception hall and thoughtful customer lounge provide customers with a comfortable environment, spacious maintenance workshop and more than a dozen standard workstations, which fully meet the needs of maintenance operations. Complete specifications, high-quality and pure accessories ensure the safety of Nissan series vehicles. Our store is a large 4s store, and its sales and service models are: Teana, Yida, Tiida, paladin, Sylphy, Liwei, Junyi and so on.

This shop not only has a group of high-quality and skilled automobile maintenance technicians, but also buys a group of advanced automobile maintenance testing equipment from home and abroad. For example: computer detection analyzer, fuel injection cleaning analyzer, four-wheel locator, atf automatic cycle cleaning, etc. The software and hardware of the factory are perfect.

The three-month internship has given me a deep understanding of the maintenance of cars and the necessity of maintenance.

Car maintenance is very important. If you buy a new car, you must first know how to maintain it. Several tasks to be done in automobile maintenance;

1, clean the appearance of the car, and check whether the door and window glass, wiper, indoor mirror, rearview mirror, door lock and lifting handle are complete and effective. Check whether the water quantity of the radiator, the oil quantity of the crankcase, the oil storage quantity of the oil tank and the electrolyte level in the battery meet the requirements. Check whether the horn and lighting are complete and effective, and whether the installation is firm. Check whether the connecting parts of the steering mechanism are loose and firmly installed. Check whether the tire pressure is sufficient and remove impurities between the tire and the wheel track. Check whether the running clearance of the steering wheel meets the standard; Whether the hub bearing and steering knuckle kingpin are loose. Check whether the free travel of clutch and brake pedal meets the requirements.

2. Check whether the tire nut, axle bolt, leaf spring riding bolt and U-shaped bolt are firm and reliable. After starting the engine, check whether the instrument works normally and listen to the engine for abnormal sounds. Check whether the vehicle has "four leaks" such as water leakage, oil leakage, air leakage and electric leakage. Check whether the traction device works reliably.

3. Change the engine oil. The main functions of engine oil are lubrication, cooling, sealing, cleaning, rust prevention and preventing engine corrosion ... Without engine oil, the heart of a car can't work normally. Use mineral oil, and generally change the oil every 5000 kilometers. 4. Inspection and replacement of automobile brake fluid: Check the brake fluid after the automobile runs for a certain period of time and replace it if necessary. After being used for a certain period of time, the brake fluid will have different degrees of boiling point reduction, pollution, oxidation deterioration and other phenomena. The quality and performance of brake fluid should be checked in time according to the climate, environmental conditions, seasonal changes and working conditions, so as to replace it in time. Under normal working conditions, the brake fluid should be replaced after 2 years or 50,000 kilometers. In principle, different types of brake fluid should not be mixed, so as to avoid chemical reaction between them and affect the braking effect. Different models often use different brake fluids. Brake fluid includes mineral oil brake fluid and synthetic brake fluid.

However, what impressed me the most was not only the professional internship, but also some internship experiences.

Understanding of finding an internship;

College students' internship is a transitional stage from college life to social work. There is a big difference between school and society. When some students are at school, they seldom think about their future jobs and seldom prepare. Once you step into the society, you are psychologically blank. Entering the society, I am not sure about what I want to do, what skills I have and what materials I have. Therefore, internship is particularly important.

There is no difference between an internship and a normal job. If the internship has no direction, then if you want to find the direction in the future, you may take a detour. Also, for many students, it is best to get a job first and then choose a job. After all, there is little contact with the society at school, and there is still a certain gap between the practical operation and application ability of the major and the actual work requirements. Don't start thinking about finding a good job, a job in your major or a job you like, which is not practical enough.

Work summary:

1. It is best to keep a work diary every day. Before going to work in the morning, write down your work goals, key issues to pay attention to in your work, and what you want to ask clearly. Then, before I get off work every day, I will look at what I did that day, what work goals I didn't complete, why I didn't complete them, and what problems I should pay attention to in my future work ... This will be very important, and I will make great progress if I watch it often.

2. In the work, if you encounter some unclear places, you must ask your superiors or teachers clearly. You can't imagine things out of thin air and do things indiscriminately. What you have done is likely to be reworked.

In the internship, it is very likely that you will encounter something contradictory with your immediate supervisor. If it has happened, we should think about why it happened and whether it can be avoided. If it can be avoided, we should pay attention to it in future work.
