What is the manual diagnosis method of automobile?

Cars have become an essential tool for everyone to travel. Of course, automobile knowledge is essential. In order to make it easier for everyone to understand this knowledge, today, Bian Xiao will introduce the manual diagnosis method of automobiles. Interested friends can learn about it, which may be helpful to you.

The manual diagnosis method of automobile refers to a diagnostic method in which a diagnostician with rich practical experience and necessary theoretical knowledge detects, tests, analyzes and determines the cause and local position of automobile problems with the help of simple detection means such as eyes, ears, hands and nose. Manual experience diagnosis is the traditional and basic method of automobile problem diagnosis. Even with the rapid development of modern instrument diagnosis technology, manual experience diagnosis may not be replaced. According to the complexity of automobile diagnosis technology and the development level of automobile technology, diagnosis methods can include artificial experience diagnosis, simple instrument diagnosis, accurate detection diagnosis and artificial intelligence diagnosis. Manual diagnosis: Before 1950s, the automobile structure was simple and there were few electrical equipment, so the problem diagnosis could be completed by manual experience. At present, the artificial experience diagnosis method is still very effective in the diagnosis of some complex problems. Simple instrument diagnosis: From the early 1950s to the late 1970s, with the increasing complexity of automobile structure, the number of electrical equipment has gradually increased. Therefore, in the process of automobile problem diagnosis, it is necessary to check related assemblies and parts with the help of vacuum gauge, pressure gauge, multimeter and oscilloscope to determine their technical status. Precision detection and diagnosis: From the early 1980s to the early 1990s, with the improvement of the electronic level of automobiles, the dynamic random problems and the function problems of the regulating system are increasing. Various precision detection methods with computer technology as the core are widely used, which greatly improves the level and accuracy of automobile condition detection and the accuracy of problem diagnosis. Such as various engine analyzers, computer test instruments, various electronic test instruments, etc. Basically, it is a necessary instrument for precision inspection. Manual diagnosis: Since 1990s, the electronic equipment of automobiles has been increasing day by day, and the models and their adjustment techniques are not very similar. Therefore, in automobile maintenance, problem diagnosis becomes a key problem. Various systems developed by applying the theory and technology of artificial intelligence and modern information technology will be beneficial to the diagnosis and solution of problems.
