Abstract of model text of automobile maintenance work 1 This training course is a short-term training course sponsored by Tianjin Engineering Teachers College and funded by Japan. It has been successfully held for three times. For our young teachers, our professional knowledge is not mature, and our educational experience is not rich. We are very eager to improve our professional knowledge quickly, so it is a rare opportunity for such teachers to further their studies. Now summarize this training.
First, the concept of automobile maintenance
Automobile maintenance changes from fault maintenance to regular maintenance and fault prevention; In addition to automobile maintenance, maintenance enterprises with a certain scale also engage in vehicle sales, spare parts supply, technical consultation, used car trading, accident vehicle maintenance and other businesses; Maintenance enterprises have a strong sense of service and quality. Quality is to satisfy customers? 、? Zero quality defect? 、? Quality is our future? Slogans can be seen everywhere in the workshop; Because the vehicle design pays attention to the overall reliability, the garage is mainly based on minor repairs, most of which are replacement repairs, and there is generally no overhaul process.
With the wide application of automotive electronic technology in automobiles, China automobile maintenance inspection equipment manufacturers have also developed and produced engine inspection and diagnosis equipment such as Repair King, Electric Eye, exhaust gas analyzer and Ignition Tester. However, their functions are relatively simple, and there is still a certain gap between China and foreign countries in inspection and diagnosis technology.
Second, the status and role of automobile diagnosis in the process of maintenance and production should be paid attention to by domestic counterparts.
Automobile diagnosis workshop is the most important link in the maintenance process, and the work of maintenance workers is mainly based on the results of automobile diagnosis. The automobile diagnosis workshop has a special automobile diagnostician (? Car doctor? ), according to the diagnosis results of electronic equipment and personal experience to determine the vehicle fault location and maintenance methods. In our country, this mode of operation has not been fully established, and there is no special one? Car doctor? Although it is required to carry out diagnosis and testing before automobile maintenance, it is specially equipped with? Car doctor? It is rare for enterprises to detect and diagnose automobile faults. Maybe some enterprises use maintenance workers instead? Car doctor? It is an improvement to be able to diagnose and repair, but with the continuous progress of automobile technology and the continuous improvement of automobile maintenance specialization, automobile doctors? It is bound to become a key position in automobile maintenance, and the automobile maintenance union is increasingly unsuitable for this role. Therefore, speed up training to meet the needs of the development of China's automobile maintenance industry? Car doctor? , is an important task for industry personnel structure adjustment and quality improvement in the future.
Three, high-quality professional skills, professional theory teaching, let me benefit a lot, all aspects have been improved.
During the training, we realized a development direction of modern automobile and the demand for talents in modern automobile industry. At the same time, I feel the gap between schools and factories in teaching content, methods and means, and understand why we should proceed unswervingly. Dual system teaching? Reform: The factory needs skilled workers who are qualified for a certain position, and our vocational education should meet this demand! Otherwise, the students we have trained will not be recognized by the society. So? All-round development of students should not be the direction of our higher vocational education. Every school should fully consider the actual situation of the school, measure it from the aspects of school equipment, teachers, quality of students, enrollment ability and communication ability between schools and enterprises, organically combine school education with enterprise employment, and make running a school truly an inexhaustible running water.
In addition, after this training, we have a certain understanding of the lifestyle of workers, the management system of the company, the sales of products and the competition in the same industry in the market, which is a rare asset for us.
Through this training, I have more realized the concern of school leaders for young teachers. I will work harder and try to do it? Double teacher? Hit a teacher. For a person, learning is life, learning is work, and learning is a responsibility. Learning is an important part of a person's life, so we must form the habit of learning anytime and anywhere. ? Only when learning is wonderful can life be wonderful; Only by studying successfully can life be successful. ? The relevant person in charge of the Department of Basic Education of the Ministry of Education pointed out that it is impossible to train teachers in advance, and the growth of teachers is linked to the deepening and development of reform. In the process of reform, teachers constantly discover and solve problems, update educational concepts, change teaching methods, improve teaching behavior, and realize the improvement of professional level.
To sum up, through this summer training, teachers have gradually established a correct educational concept, constantly improved their knowledge structure, mastered the latest trends of curriculum reform and teaching reform, improved their ability to perform their duties, and more adapted to the needs of implementing quality education. The key to the construction of teachers' team is to build with heart. Mr. Tao Xingzhi, a famous educator, said: Education is a kind of soul-to-soul activity, and only from the heart can it reach the depths of the soul. ? Work hard! We firmly believe that as long as we treat every student sincerely, trust every student and leave more opportunities and more thoughts to students, our harvest will not live up to our sowing.
Working Mode of Automobile Maintenance Text 2 Summary With the popularization of automobiles in China, the development of new automobile technologies has triggered the changes in the automobile aftermarket. In the 20th century, automobile technology changed with each passing day with the progress of society. From the point of view of vehicle technology, the automobile has many automation functions because of the extensive use of microcomputer technology, which greatly improves the power, maneuverability, adaptability and safety of the automobile. The reliability and service life of automobiles have been greatly improved.
The development of new automobile technology has greatly promoted the great changes of automobile maintenance technology and system and enterprises. The automobile maintenance industry has never faced such a big impact as today. It is difficult for the previous automobile maintenance mode to adapt to and deal with any of the above technologies. Automobile maintenance technology has gradually separated from the traditional experience maintenance mode, but increasingly relies on high technology, computer diagnosis and data analysis. The requirement for technicians has also changed from mastering only a single subject in the past to a level with strong comprehensive quality of mechatronics. At the same time, it also promotes the improvement of automobile maintenance technology in China.
I have been engaged in automobile maintenance since I joined the work. At work, I seriously studied professional theoretical knowledge and traffic laws and regulations, and actively studied and explored automobile-related theoretical knowledge, which improved my maintenance technology. So far, my technical level and professional quality have been effectively improved. In the specific work, we have mainly done the following work:
1. Pass? Do you see it? Understand the purpose of the vehicle
(1) Check whether the fault light on the instrument panel is on or off, and determine whether it is the fault of the electronic control system or the mechanical system. For example, a Fukang 988E_? 1 The vehicle is idling, with poor acceleration performance and high fuel consumption, and the instrument light is displayed normally. Through inspection, it was found that the air flow guide net accumulated dust, and the acceleration performance returned to normal after cleaning.
(2) Regular? Five oils, three liquids and one medium? Inspection can not be ignored, that is, the inspection of turbine oil, engine oil, automatic transmission oil, steering power oil, gear oil, brake fluid, coolant, wiper cleaning fluid and refrigerant. The instrument lights on most luxury cars are displayed in English. If the cleaning liquid light is on, check the liquid level in the cleaning liquid and the reservoir, and the warning light can be turned off after adding. For example, the ABS light of an Audi A62.8L car is on, which seems to be a big problem. The owner rushed to Audi A6 maintenance center for maintenance. After inspection, it was found that the liquid in the brake fluid container was below the warning line. How easy it is to solve the problem after replenishing brake fluid.
(3) The fault can be judged by the quality of the liquid in the vehicle parts. The automatic transmission oil of a Guangzhou Honda Accord 7230 car turned purple with a small amount of impurities. At this time, the driving force is insufficient and the starting speed is too slow. Therefore, according to the color of the oil, it can be concluded that the fault is due to the fault of the automatic transmission rather than the lack of engine power. Disassemble the oil pan for inspection, which proves that the judgment is correct.
(4) It is equally important to check the line. Citroen's left front wheel does not rise or fall, and the other three wheels run normally. It was found that the exhaust valve line of the left front air spring damper was disconnected, and the left front wheel movement returned to normal after the line was connected. In the process of reading, we should look at it carefully, carefully and analytically, rather than skim it, so as to get twice the result with half the effort.
2. Ask the owner or driver about the situation before and after the vehicle failure.
The driver knows the vehicle he is driving best, which is the first-hand information to judge the fault. Generally speaking, limousine drivers attach great importance to vehicles. It is understandable that they will go to the repair shop to check the slightest change, so the information they provide is very important. For example, a Beijing Cherokee 4.0L Jeep has poor acceleration performance, difficult starting, high fuel consumption and black smoke from the exhaust pipe. Upon inquiry, the vehicle has traveled1.2000 km, and no other project operations have been carried out except the maintenance of engine oil and three filters. The fault has been driven 10000 km since it appeared, and the fault is getting worse and worse, and the exhaust smoke is more serious. Therefore, it is concluded that the spark plug gap is too large, and the gap between the two electrodes is close to 2.5mm after disassembly and inspection. After replacing the spark plug, the fault is eliminated. Another example is a Lincoln Continental car with poor acceleration performance. After asking the driver, I learned that it was caused by replacing the spark plug. Remove the spark plug to see that its model meets the requirements, and conclude that its ignition sequence is wrong. It runs normally after correction. Another example is a Mercedes-Benz 560ES car, which is not easy to start after replacing the spark plug. Upon inquiry, the gap between the installed spark plug and the ordinary spark plug is the same. After correction, it starts normally.
In short, the above are special cases, not to say that it is ok? Ask? You can get the right basis. Because the driver's qualification, experience and mastery of vehicles and performance are at different levels, so in? Ask? When looking for the key, heavy
Ask important phenomena, and the answer to the driver should be able to discard the false and retain the true. This is very difficult for maintenance personnel, and the key lies in whether the vehicle structure and performance are thoroughly understood. This requires maintenance personnel to accumulate theoretical knowledge and practical experience at ordinary times. Based on this, how can I ask? The importance can be fully reflected.
3. use? Smell? Judging the fault point
Through oil? Smell? We can know the quality of engine oil and the basic working condition of the system, and we can feel the working condition of the engine by smelling the exhaust gas of the engine, thus providing guidance for fault judgment. Such as a Santana 2000GSi car, the idle speed is unstable, and the sudden acceleration jitter is serious. Through the analysis of tail gas odor, it is considered that high-voltage lines sometimes fail, and the failure should be eliminated after replacement. Smell? It is relatively less used in maintenance than other means, but it does not mean that it is not important. Using it correctly in fault judgment can save us a lot of detours.
4.？ Listen. This is also a common skill of maintenance personnel.
What is the most frequently heard sentence? The level of so-and-so is really high. Sitting at the gate, the car passed by him and knew what was wrong. . Although this statement is somewhat exaggerated, it also shows the importance of listening in maintenance. Listen, we must first find out the location of the fault and identify the type of noise. Besides, in the current fault analysis, most of them are mechanical faults. So what? Listening? It is the basic skill of maintenance personnel. If you can't find the fault location, you will take many detours in maintenance and waste manpower, material resources and financial resources. If it is an engine fault, it cannot be judged as an automatic transmission fault. For example, a Passat car in Shanghai has a slight abnormal noise after preheating. Because the car is equipped with an automatic transmission, it is impossible to judge the fault position by stepping on the clutch pedal. After auscultation, it was found that the excessive clearance of connecting rod bearing in cylinder 6 led to abnormal noise of the engine.
A mature maintenance worker should carefully summarize the characteristics of various noises, such as continuous and intermittent noises, creaking and low noises, regular and irregular noises, etc. It is necessary to learn some special structures, and it is also practical to master them well. For example, a car with air suspension can't talk about oil leakage of shock absorber, and a car with automatic transmission can't talk about manual clutch. Through the continuous accumulation of listening experience, we can turn the existing theory into a practical skill, and our level can be continuously improved.
5. Test run
In the past, maintenance personnel only engaged in maintenance work, and had no perceptual knowledge of vehicle maintenance and after maintenance, and had no in-depth understanding of faults, so the accuracy of fault judgment was poor. Debugging should be the basic skill of maintenance personnel. You can learn a lot of knowledge that is not available in books through trial operation. For example, after the automatic gear is repaired, it will run normally when it is empty, and it is likely that the vehicle will not be able to drive after it is put into gear when it is loaded, and it will stall at high speed and the direction will tremble when braking. If there is no personal feeling, it will cast a veil over the judgment of fault, leading to hesitation and uncertainty in judging fault. Therefore, the trial operation can inspire our maintenance work and speed up the troubleshooting.
The above methods are not independent, and the effect of comprehensive application will definitely make you ahead of others in maintenance and fault diagnosis and become an expert in maintaining luxury cars.
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, every day before I get off work, I will look at what I did that day, what work goals I didn't accomplish and why I didn't. It will be very important for me to pay attention to those problems in my future work. If I look at them often, I will make great progress.
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.
When discussing a problem, you should have your own point of view, you can't follow the trend and you can't have no point of view.
5. Work should be down-to-earth, and everyone should really do it, sum up more and communicate more.
Although my internship in this company is not long or short, I have learned a lot of knowledge we want to learn in this company, which has given me a better understanding of the automobile industry. I know that what I learned at school is limited, and there is still a lot of knowledge I don't know. During my internship, I seriously studied the knowledge of automobiles with the masters, actively started work, cultivated my hard-working spirit, and carefully understood the body structure. I completed the disassembly and assembly of auto parts, met the requirements of internship, and learned about the corporate culture and management system in the enterprise. Not only did I make a breakthrough in my major, but I also learned the knowledge of enterprise management. Generally speaking, I have successfully completed this internship, which will play an important role in my future work.
Summary of automobile maintenance work: 20 _ _ was a year of great-leap-forward development for our company. During this year, our company earnestly studied the working spirit of the 18th National Congress of the Communist Party of China, conscientiously implemented the document spirit and work instructions of provincial and municipal transportation management bureaus, industrial information committees, quality supervision bureaus, transportation bureaus and traffic police departments, effectively established and improved the company's safety production and safety prevention and control system, strengthened supervision, and implemented various safety management responsibilities with the help and guidance of department leaders at all levels.

4, production equipment do a person create posts, specialist use and regular maintenance, it is forbidden to mechanical production equipment in spite of illness or overload operation.
5. Debugging and maintenance of modified vehicles, shifting of workshop vehicles, and prohibition of driving or road test by employees without driver's license.
6. Strictly implement the safety production management measures formulated by the company, turn off the power supply, mechanical equipment, close the doors and windows, tidy up the tools and clean the workshop before coming off work, and consciously eliminate hidden dangers.
Second, the quality of service.
In order to improve the quality and service level of automobile maintenance, our company has established? Quality is the soul and life of traffic safety? Slogan, work hard to build? Integrity and quality service unit? Signboards provide convenient, timely, high-quality, reliable and reasonably priced maintenance services for the majority of automobile users, safeguard the legitimate rights and interests of consumers, establish a good social image of the automobile maintenance industry, build a good corporate brand and promote business development.
Establish and improve various management systems in accordance with regulations, publicly guarantee the maintenance quality, sign maintenance warranty contracts for all modified gas vehicles for more than one year, and make commitments to customers to ensure quality; Open maintenance man-hour quota and charging standard, and charge reasonably; Open the price of auto parts so that customers can choose freely; Open the basic information of enterprise technical leaders and maintenance technicians, and widely accept the supervision of car owners and society. For maintenance enterprises above Grade II, relevant technical standards and specifications are put on the wall, requiring maintenance operators to strictly implement technical standards and specifications, and at the same time, let consumers know the contents of technical standards and specifications, and enhance their awareness of rights protection and self-protection ability.
In order to further improve the quality of refitting and maintenance of natural gas vehicles, improve the quality of business services, improve the technical conditions of vehicles in use, and ensure the safety of vehicles, according to relevant laws and regulations, we are now conscientiously doing the following daily work:
1. Strictly abide by the Regulations of the People's Republic of China on Road Transportation, Technical Requirements for Modification of Gas Vehicles, Regulations of the Ministry of Communications on Motor Vehicle Maintenance and other laws and regulations, operate in good faith and legally, strengthen quality management, and improve the technical level of maintenance.
2, establish and improve the maintenance quality supervision and management system, clear job responsibilities, responsibility to the people; Quality management should start from the source, ensure the quality of personnel, technology, parts warehousing and equipment and instrument appraisal, hold regular quality analysis meetings, and establish? Strive for development by quality? Business philosophy.
3. Strictly implement the technical specifications and standards related to motor vehicle maintenance technology, and earnestly implement them? Three inspections? System, dispatch work order system, factory certificate system, do a good job in refitting maintenance records, improve the maintenance technical files, make one car and one file, keep the files permanently, and do a good job in tracking maintenance services.
4. Strengthen the management of spare parts, improve the system of purchasing, keeping and receiving spare parts, and have the warehousing acceptance sheet and quality spot check records, which do not appear? Three no? Or fake and shoddy products.

6. Implement the quality guarantee period system, do a good job of quality information feedback, and take timely measures when motor vehicle failures caused by maintenance quality occur during the quality guarantee period? Free maintenance? And other remedial measures, repair rate control below 5%.
7. Make a public commitment to the society: warm reception, excellent service, honesty and trustworthiness, reasonable fees, and put an end to counterfeiting activities; Business households openly make service promises of standardized operation, quality assurance, civilized production and supervision. Provide customers with free automobile exhaust detection, four-wheel alignment and tire dynamic balance detection, and provide technical advice on the use and maintenance of modified cars; Do a good job in the follow-up work of service quality, and create a harmonious market environment for modification and maintenance in various forms.
After nearly two years of construction and operation, our commercial functions in all aspects have been continuously improved and our economic carrying capacity has been continuously improved. But overall, the business framework has not been fully opened, the existing infrastructure has just been fully built, and the business environment has been initially improved, which can not meet the needs of the company's rapid development. We must firmly grasp the technical strength and service attitude, further intensify the operation, enhance the company's absorption and aggregation function and external attraction, and enhance the market competitiveness.
Although the company's operation has made remarkable achievements, which have been recognized and praised by customers and competent departments, there are still many aspects that cannot meet the requirements of our customers, such as small production and operation area, relatively closed geographical location, and irregular modification operation. We must firmly establish? Responsible for customers, tap potential and increase efficiency? Business philosophy, unremittingly do a good job in service quality construction, establish a good image of the company, and create good work performance.
In the new year, our company has clearly defined its development tasks, conscientiously studied the spirit of the 18th National Congress of the Communist Party of China, sought truth from facts, set out from the height of the company's development, set out from all the purposes of serving customers, set out clear objectives, highlighted key points, worked hard, and established a set of management systems with clear responsibilities and reasonable rewards and punishments. Really let the sage have his place, do it if he can, really widen the income level according to his work ability, work attitude and work performance, encourage every employee to work with greater enthusiasm, enthusiasm and better technology, and create a new situation of automobile maintenance and natural gas modification in Wuwei area and contribute his own strength.
