The most common sentence I hear is "So-and-so's level is really high. When he sits at the gate, he will know where the problem is when a car passes by him." Although this is a bit exaggerated, it also shows the importance of maintenance. To listen, you must first clarify the location of the fault and the type of sound. Moreover, in current fault analysis, the most common faults are mechanical faults, so "listening" is a basic skill for maintenance personnel. If the fault location cannot be found accurately, many detours will be taken during maintenance, which will waste manpower, material and financial resources. If it is an engine failure, it cannot be judged as an automatic transmission failure. For example, a Shanghai Passat makes a slight noise after it is warmed up. Since the car is equipped with an automatic transmission, it is impossible to determine the location of the fault by depressing the clutch pedal. After auscultation and final disassembly and inspection, it was found that the 6-cylinder connecting rod bearing had excessive clearance, causing abnormal noise in the engine.
A mature maintenance personnel should carefully summarize the characteristics of various sounds, such as continuous and intermittent sounds, crisp and muffled sounds, regular and irregular sounds, etc., and determine whether the sound is It is necessary to learn some special structures, and it is very practical to master them well. For example, you cannot talk about shock absorber oil leakage for vehicles equipped with air suspension, and you cannot talk about manual transmission clutches for vehicles equipped with automatic transmissions. Through the continuous accumulation of listening experience, existing theories can be upgraded into a practical skill, and one's own level can be continuously improved.

Drivers know the condition of the vehicle they drive best and are the first-hand information to determine faults. It is understandable that the average limousine driver attaches great importance to the vehicle and will go to the repair shop to inquire about any minor changes, so the information they provide is important. For example, a 4-cylinder 1.6L EFI Jetta Avant-garde car has poor acceleration performance, severe shaking while driving, and stalling while driving. After asking the driver, the driver said that this situation occurred after driving a long distance on a rural dirt road. We suspected that the air intake passage and oil passage were dirty, so we replaced the air filter element, gasoline filter element and car pump filter as usual, and cleaned each channel of the throttle valve and the four injectors. During disassembly, it was found that they were relatively dirty. After cleaning and reassembly, they were tested and the fault was eliminated.
In short, the above are some special cases, which does not mean that the correct basis can be obtained through "asking". Since the driver's qualifications, experience and mastery of the vehicle and performance are at different levels, when "asking", it is necessary to look for key and important phenomena to ask, and the driver's answers must be able to eliminate falsehoods and retain the truth. This is very difficult for maintenance personnel. The key lies in a thorough understanding of the vehicle structure and performance. This requires maintenance personnel to accumulate theoretical knowledge and practical experience. Only with this, the importance of "asking" can be fully reflected. Auto Repair Annual Work Summary 4
Time flies so fast, and before you know it, the year is at the end of the year. Looking back, I have gained a lot this year. Thanks to my masters for their dedicated teachings. My growth is inseparable from them!
1. Goals accomplished this year
When I first became a full-time employee, I set a goal to standardize my maintenance process. This year, I will eliminate all plastic surgery, door replacement and minor accidents. You must be able to complete it independently, and you must master the repair technology of large-scale accidents as soon as possible; at the same time, you must also get rid of your carelessness, improve the quality of repairs, eliminate the repair rate, and do a good job on every car carefully. This is not only Being responsible for customers is also responsible for yourself; at the same time, you must learn as soon as possible, learn the skills to the best of your ability, and strive to be able to repair alone.
Now it seems that the original goal has been achieved. After the car comes, I can repair it by myself. Both the repair process and the quality of repair have been greatly improved; I am no longer the rookie!
I also have some shortcomings in my daily work, and I am a bit careless in doing things. Although my talent is not as good as others, I am not afraid of getting dirty, tired, and willing to learn; otherwise, I will be "eliminated"!
2. New goals for next year
1. Further standardize your own maintenance process, improve your own maintenance quality, and try to eliminate repairs;
2. Master it as soon as possible The key points of major accident repairs are to become proficient in using and repairing them as soon as possible;
3. Participate in more trainings to strengthen your skills and learn new maintenance techniques;
4. As much as possible Improve your maintenance efficiency and repair the most vehicles in a limited time;
In the new year and new atmosphere, adjust your mentality, grow in training, and hone in work. Meet the new challenges in 20xx! Automobile repair annual work summary 5
In 20XX, I graduated from x college, majoring in internal combustion engine manufacturing and maintenance of the company. I just graduated from college and came to work in the company. During my work, through serious internship and diligent practice, I gradually mastered the basic requirements of modern vehicle repair. I have made some progress in all aspects. I will now report on my work. Please point out any shortcomings!
1. There are roads in the mountains of knowledge, but there are no boundaries in the sea of ??skills
After arriving at the maintenance and manufacturing center, I knew that as a skilled worker, if you can’t understand the drawings and materials, you won’t be able to do anything. If you don't understand the principles of the equipment and cannot penetrate the structure of the vehicle, you are not only very embarrassed, but you are also not a qualified worker. I overcame unfavorable factors such as lack of practical experience, and worked hard to "recharge" myself with a "bull spirit" that would not give up until I reached my goal. I compiled some useful technical books, studied in depth technical theories such as "Vehicle Structure" and "Mechanical Fundamentals", and applied the knowledge I learned to actual production to continuously improve my professional skills. Sometimes, in order to find out the ins and outs of a certain accessory, I compared technical information and spent all night pondering and researching. I would never let go until I understood it. Sometimes, if I couldn’t finish something in the workshop, I would take it back to the dormitory to study. Over time, my dormitory became My "research institute". Hard work pays off. After hard study, I have made rapid progress, but I am not complacent at all. I know that although I am a college student, many masters in the maintenance and manufacturing center are very experienced and are role models for me to learn from. On the road of professional technology, there is no room for hypocrisy and slackness. We must use our unremitting efforts to continuously make new contributions to the enterprise.
2. Have the courage to tackle difficult problems and solve them
I used my intelligence and the professional skills I learned to work with the masters to solve problems for the maintenance and manufacturing center and overcome them. One difficulty after another. In April this year, the maintenance and manufacturing center notified me that there was a car that had to be shifted into reverse gear with load. It had been repaired several times but could not be repaired. As soon as the car arrived for repair, the master and I immediately brought the tools and tested it with the driver. During the drive, we found that On desert roads, reverse gear automatically jumps. The driver said: The problem appeared three months ago, but the problem can't be found. After discussing with the master, I determined that the cause of the "reverse gear cage slipping" failure was caused. The driver said that it had been replaced and no problem was found. After the test drive came back, the master and I checked again in detail and determined that the reverse gear was slipping. After disassembling the gearbox, it was discovered that the gear cage used in the reverse gear was abnormal. Although the size was the same, the shape of the teeth was different. This was the direct cause of the gear change. After the replacement, the fault was successfully eliminated, which not only relieved the driver's worries, but also saved the company a lot of money.
3. Be dedicated to your job and serve enthusiastically
"Stand to be a man, kneel to serve" is the service concept of the transportation company. At work, I see many vehicles appearing while driving. I conducted an in-depth analysis of this type of problem and concluded that there are several reasons why the vehicle's brakes are not working properly: The compressed air pressure generated by the brake system is insufficient.
Because the vehicle's air reservoir cannot store enough compressed air, the air supply to the brake valve is insufficient; air leakage in the brake valve pipeline and blockage of the air path will cause insufficient compressed air pressure generated by the brake system during braking; the brake drum and The brake shoe clearance is inappropriate; the brake shoe contact area is too small. Based on the above reasons and around the problem of brake failure, I repeatedly checked and studied the relevant maintenance information, and humbly asked experienced masters for advice. I checked and analyzed the possible causes one by one, and identified the parts that may malfunction. , adopt the method of starting from the shallower to the deeper, easy first and then difficult. I first check the air storage tube to see if the air pressure meets the standards. Start the engine and check the response of the pressure gauge of the brake system. It is found that it is difficult to inflate. It takes >xmin to charge to xMPa. In this case, it may be that the air compressor is faulty, or there may be a leak in the sealed air pressure pipeline, making it difficult to increase the air pressure. I checked the air pressure when the engine was running at medium speed and found that it rose slowly. After turning off the engine, I checked the air pressure and found that the pressure dropped rapidly and exceeded the standard value. Check whether the tightness of the air compressor transmission belt meets the requirements, and then remove the air compressor. It is found that most of the pump cover is covered with carbon deposits, and the air valve is also blocked by carbon deposits. After removing the carbon deposits, reinstall the pump cover and accessories for testing. It is found that the effect is improved than before. The air compressor has obvious pumping sound and the working effect is good. Then connect the output of the air compressor to the air hose and continue to start the engine. Each section of pipeline in front of the valve is loosened section by section to test the air volume, and then the carbon deposits on the blocked pipelines are completely removed.
Through the above operations, after the engine is started, the air pressure can quickly reach above xkPa. I judged the fault based on the drop in air pressure after depressing the brake pedal. I found that the drop in air pressure was normal, but after releasing the pedal, the exhaust volume of the exhaust valve was insufficient. I immediately disassembled the brake master valve and checked the intake valve. There were obvious grooves in the glue, and the exhaust valve's glue had swollen and was not closing tightly. After replacing and reinstalling it, I adjusted the exhaust valve appropriately, and then I removed the brake shoe and brake drum in the rear wheel. The gap between them should be appropriately adjusted to the position so that there will be no drag. And check whether the push rod extension stroke of the front and rear four-wheel brake chambers reaches the specified value. The push rod stroke of the front wheel should be xmm and the push rod stroke of the rear wheel should be xmm. Unexpectedly, during the inspection and adjustment process, it was discovered that the push rods of the left and right wheel brake chambers were laborious to expand, slow and inflexible. After disassembling the air inlet pipe of the brake chamber, air is discharged. It is confirmed that the air pipe joint is not blocked and the valve glue is not leaking. This indicates the cause of this phenomenon. It may be that the lubrication is not thorough enough during the first-level maintenance process, or it lasts for a long time. The loss of grease caused the camshaft and bushings to corrode, causing difficulty in pushing the push rod and reducing the stroke.
Therefore, I jacked up the wheel, then turned the wheel and tried to depress the brake pedal. Sure enough, the wheel did not stop immediately. It stops slowly, which proves that the camshaft has lost its function. Immediately remove the left and right wheels and brake cam push rods, remove rust, lubricate and adjust them, clean the entire brake drum, and check the tension of the return spring of the brake shoe. Intuitively, the spring has been There was a lot of rust. I compared the old and new springs to confirm that there were differences in elasticity and thickness, so I replaced them with new ones. After replacing it with a new one, the fault was eliminated. After a test run, the original brake failure of the vehicle was eliminated.
4. Strengthen self-cultivation and move closer to the party
As the saying goes: "Live until you are old and learn until you are old." I have been strictly demanding myself in all aspects and working hard to improve myself so that I can adapt to the situation of social development more quickly. Actively study political theory through newspapers, magazines, and books; by reading a large number of moral cultivation books, have the courage to dissect yourself, analyze yourself, face yourself squarely, and improve your own quality. Observe disciplines and laws, study legal knowledge seriously; be dedicated to work, be proactive and study professional knowledge seriously, have a correct work attitude and be serious and responsible. Auto Repair Annual Work Summary Chapter 6

Through on-site maintenance internships and communication and guidance with company employees, connect theory with practice, confirm, deepen, consolidate and enrich the theoretical knowledge learned, cultivate the ability to analyze and solve practical engineering problems, and provide Lay a solid foundation for subsequent professional knowledge learning, course design and graduation project.
3 Maintenance internship is a comprehensive ability cultivation and training for students. During the entire internship process, students' subjective initiative is fully mobilized, and their hands-on ability is improved by observing and practicing in depth and detail.
2. Internship content:
This company not only has a group of high-quality and highly skilled automobile maintenance technicians, but also purchases a group of advanced automobile maintenance equipment from domestic and foreign countries. Testing equipment. For example: computer detection analyzer, fuel injection cleaning analyzer, four-wheel aligner, atf automatic cycle cleaning, etc. The factory has both software and hardware and is complete.
Have a complete maintenance service process, the process is as follows:
1. Car maintenance
Car maintenance is very important. When buying a new car, you must first Know how to maintain it. Several tasks need to be done for car maintenance:
Clean the exterior of the car and check whether the door and window glass, wipers, interior mirrors, rearview mirrors, door locks and lift handles are complete and effective. Check whether the amount of water in the radiator, the amount of engine oil in the crankcase, the fuel reserve in the fuel tank, and the electrolyte level in the battery meet the requirements. Check whether the speakers and lights are complete and effective, and whether the installation is firm. Check whether the connecting parts of the steering mechanism are loose and whether the installation is firm. Check whether the tire pressure is sufficient, and remove debris between the tires and tread patterns. Check whether the steering wheel's free play meets the standards; whether the wheel hub bearing and steering knuckle king pin are loose. Check whether the free travel of the clutch and brake pedal complies with regulations.
Check whether the tire nuts and axle shaft bolts are firm and reliable. After starting the engine, check whether the instruments are working normally and listen for any abnormal noise from the engine. Check the vehicle for water leakage, oil leakage, air leakage, electricity leakage, etc. Check whether the towing device works reliably.
The main functions of engine oil are to lubricate, cool, seal, clean, prevent rust, and prevent corrosion of the engine. Without engine oil, the heart of the car cannot operate normally. Use mineral oil, and generally change the oil every 5,000 kilometers. The correct oil change standard is calculated based on engine running time. (Self-estimated average speed: kilometers/hour) x (100 hours/mineral oil-200 hours/synthetic oil) = oil change kilometers.
Car brake fluid inspection and replacement: The brake fluid must be checked after the car has been driven for a certain period of time and replaced if necessary. After the brake fluid is used for a certain period of time, it will experience reduced boiling point, pollution and varying degrees of oxidation and deterioration. Therefore, its quality and performance should be checked in time according to climate, environmental conditions, seasonal changes and working conditions, and timely replacement should be achieved. Under normal working conditions, brake fluid should be replaced after 2 years or 50,000 kilometers of use. In principle, different types of brake fluids cannot be mixed to avoid chemical reactions with each other and affecting the braking effect. Different models often use different brake fluids. Brake fluids include mineral oil brake fluid, synthetic brake fluid and other types.
Synthetic brake fluids have many advantages and are commonly used.
In addition, professional replacement equipment should be used when replacing the brake fluid. This way, the brake fluid can be replaced more thoroughly without leaving any impurities, avoiding air lock, and effectively avoiding the common problems of manual replacement of brake fluid. question. For example, the brakes are soft or the fluid (gas) valve is damaged.
2. Replacement of engine spark plugs
Although there are no strict requirements for changing engine oil in terms of time and mileage. However, if the spark plug is not replaced for a long time, it will also affect the engine work and life. Spark plugs are generally divided into two types, one is the ordinary type, which has a service life of two years or 48,000 kilometers. Another platinum spark plug, this spark plug uses platinum material so its life span can reach 120,000 kilometers or five years. You can replace the spark plugs on most cars yourself, especially easier on four-cylinder engines. There are only two sizes of spark plugs for household cars around the world. If you want to replace the spark plugs yourself, you can go to a Toyota auto parts store, report the age and model of your car, buy spark plugs that match your car, and then borrow them from the waiter. The spark plug replacement tool can be replaced by yourself.
3. Diagnosis of common faults and selection methods of car wipers
It has been wiped more than 1 million times. According to an international driving safety survey: when driving on rainy days, the traffic accident rate caused by aging wipers is about five times higher than usual!
No, the weather is getting warmer, and the rainy season is coming. If there is something wrong with your wipers, you need to find a way to fix it quickly. We specially used the rest time on Sunday to visit the masters of several auto repair shops, and the answer we got was: prescribe the right medicine and give different diagnostic methods according to different diseases of the wiper.
Hardening of wipers: Replace wipers or rubber sheets: I wonder if you have noticed that using wipers feels good when there is no heavy rain, but when you start the wipers when it rains lightly, you will find that the wipers will leave marks on the glass surface. There will be traces of uneven wiping; sometimes it will get stuck on the glass, causing poor visibility. This condition indicates that the wipers have hardened. To troubleshoot this problem, you should first understand the working principle of the wiper. It turns out that the wiper relies on the rotation of the motor, which is converted into a back-and-forth motion by the connecting rod, and this force is transmitted to the wiper arm and the wiper itself. When the rubber part of the wiper hardens, the wiper cannot fit closely with the glass surface, or if the wiper becomes scratched, it will cause uneven wiping and form residual dirt.
Replacing the wiper or wiper rubber sheet is very simple, but when replacing it, you should pay attention to the fact that the installation method and length of the wiper are different for different models and years. Some wipers only need to replace the rubber sheet.
1. If the wiper arm is an upright type, stand it up. If it is a non-upright shielded type, wet the glass surface first. When the wiper arm is in a position that is easier to replace, set the motor switch to off.
2. The installation methods of wipers include u-hook type and screw locking type. For those with hook type, just pull up the hook and the wiper can be removed.
3. It is best to compare the length of the removed wiper with the newly installed wiper to see if they are the same, and then observe whether the installation method is the same.
4. Insert the wiper into the original position as much as possible to fix it.
5. Wet the windshield and observe whether the wiper action is normal.
If the wiper arm fails, replace the wiper arm: The wiper relies on the force of the wiper arm spring to make close contact with the windshield. When the tension of the spring becomes weak, the wipers will float or hang on the windshield due to the strong wind pressure brought to the windshield when driving at high speeds. In order to completely eliminate this problem, it is best to replace the entire wiper arm set. 1. Remove the cover from the wiper arm mounting part. 2. Loosen the fixing nut and remove it. 3. Place the wiper arm in an upright position, and then it will fall off if you move it slightly. 4. Replace the wiper body on the new wiper arm. 5. Tighten the nut at the wiper stop position, and finally install the cover.
3. Internship Summary
Although our internship time in this company was very short, we learned a lot of knowledge we wanted to learn in this company, which made us more familiar with the company. With a better understanding of the automotive industry, I know that I learned very little in school and there is still a lot we don’t know. During the internship, we carefully studied automobile knowledge with the masters and actively worked hard, which cultivated our hard-working spirit and carefully understood the structure of the car body. The purpose of car disassembly and assembly was completed and our internship requirements were met. In the company, we learned a lot about corporate culture and corporate management system. Not only did we make breakthroughs in our majors, we also learned a lot about business management. Overall, I successfully completed this internship, which played a very important role in my future work.
Part 3 of the auto repair internship report for technical secondary school students
From ** to ** in ****, I conducted maintenance internship activities at the Dongfeng Nissan ** franchise store. During these three months, I have a certain understanding and deep understanding of the vehicle sales, after-sales service, maintenance, information feedback, etc. of the automobile 4S store.
The Dongfeng Nissan ** franchise store is a first-class maintenance equipment with Dongfeng Nissan vehicles designated, supporting and directly provided: lifts, tire balancing machines, body calibration stands, paint booths, four-wheel aligners etc., it also has advanced imported testing instruments: Nissan computer detector, ignition tester, refrigerant machine, etc., as well as a computer network used for maintenance business. The spacious and clean business reception hall and the customer lounge with attentive service provide customers with a comfortable environment. The spacious maintenance workshop is equipped with more than a dozen standard workstations to fully meet the needs of maintenance operations. Complete specifications, high-quality and genuine accessories are the safety guarantee for the operation of Nissan series vehicles. The store is a large 4S store, selling and servicing several models such as Teana, Tiida, Tiida, Paladin, Sylphy, Liwei, and Junyi.
This store not only has a group of high-quality and highly skilled automobile maintenance technicians, but also purchased a number of advanced automobile maintenance and testing equipment from domestic and foreign countries. For example: computer detection analyzer, fuel injection cleaning analyzer, four-wheel aligner, atf automatic cycle cleaning, etc. The factory has both software and hardware and is complete.
During these three months of internship, I have a deep understanding of car maintenance and the necessity of maintenance.
Car maintenance is very important. When you buy a new car, you must first know how to maintain it. Several tasks that need to be done for car maintenance:
1. Clean the exterior of the car and check whether the door and window glass, wipers, interior mirrors, rearview mirrors, door locks and lifter handles are complete and effective. Check whether the amount of water in the radiator, the amount of engine oil in the crankcase, the fuel reserve in the fuel tank, and the electrolyte level in the battery meet the requirements. Check whether the speakers and lights are complete and effective, and whether the installation is firm. Check whether the connecting parts of the steering mechanism are loose and whether the installation is firm. Check whether the tire pressure is sufficient, and remove debris between the tires and tread patterns. Check whether the steering wheel's free play meets the standards; whether the wheel hub bearing and steering knuckle kingpin are loose. Check whether the free travel of the clutch and brake pedal complies with regulations.
2. Check whether the tire nuts, axle shaft bolts, leaf spring riding bolts and U-shaped bolts are firm and reliable. After starting the engine, check whether the instruments are working normally and listen for any abnormal noise from the engine. Check the vehicle for any leaks such as water leakage, oil leakage, air leakage, and electricity leakage. Check whether the towing device works reliably.
3. Replacement of engine oil. The main functions of engine oil are to lubricate, cool, seal, clean, prevent rust, and prevent corrosion. Without engine oil, the heart of the car cannot operate normally. Use mineral oil, and generally change the oil every 5,000 kilometers. 4.

In principle, different types of brake fluids cannot be mixed to avoid chemical reactions with each other and affecting the braking effect. Different models often use different brake fluids. Brake fluids include mineral oil brake fluid, synthetic brake fluid and other types.
However, what impressed me most was not only the professional internship, but also some experiences during the internship.
Understanding of finding internships:
Internship activities for college students are a transitional stage from university life to social work. There is a big difference between school and society. When some students are in school, they think less about their future work and are less prepared. Once they enter the society, they are psychologically blank. When I entered the society, I was not very sure about what kind of job I wanted to do, what skills I had, and what kind of materials I had. Therefore, internship is particularly important.
An internship is no different from working normally. If you don’t have a direction during your internship, you may take detours when trying to find a direction later in your career. Also, for many students, it is best to find a job first and then choose a career. After all, I have little contact with society in school, and there is still a certain gap between my professional practical operation and application abilities and actual work requirements. Don't think about finding a good job, a job in your major, or a job you like from the beginning. This is not realistic enough.
Work summary:
1. It is best to keep a work diary every day. Write down your work goals for the day before going to work in the morning. Key issues that should be paid attention to at work include: Those things need to be asked clearly. Then before leaving get off work every day, take a look at what work you have done that day, what work goals have not been completed, and why they have not been completed. It will be very important to pay attention to what problems you should pay attention to in future work. It will be very important if you look at it often. Progressive.
2. When working, if you encounter something that is not very clear, you must ask your superiors or masters clearly. You cannot just imagine and do things randomly. The things produced in this way are likely to be reworked. .
3. During your internship, you are likely to encounter conflicts with your immediate boss. If it has already happened, you have to think about why it happened and whether it can be avoided. If it can be avoided, you should pay more attention to it in future work.
