Engine Test a new stage of technological development

Synchronous high-speed photography,[link widoczny dla zalogowanych], a photograph can be the same as the shadow and the flame looks like, to get more information on mixing and combustion process. In experimental modal analysis theory and application of research, many of these units carried out the domestic work in this area and develop some applications. Lee 6, Shandong Institute of Internal Combustion Engine Vehicle Engine No. 1 of 1997 established a new dynamic analysis for a variety of laboratory analysis of dynamic tests, further broadening the application field; Chongqing University, using sound intensity measurement noise sources of internal combustion engine Recognition, measurement is not required to reverberation chamber and anechoic room very expensive special acoustic environment, suitable for field testing. 4 Problems and Development Strategies 9O years, China's internal combustion engine testing technology into a comprehensive period of rapid development,[link widoczny dla zalogowanych], testing technology, applied research and new test equipment development has made encouraging progress. But compared with foreign advanced level, there is still a big gap in many areas, mainly in the following areas: * special test equipment engine varieties produced incomplete, supporting the poor; * test equipment and precision components, degree of control, stability and reliability there are some gaps; • In many areas the test is still a blank in China, such as emissions of new sensors and multi-functional integrated instrument, such products also rely mainly on imports, due to their cost, the application has been largely restricted ; * lack of self-development capability. In recent years the introduction of foreign advanced production technology, test equipment, special test equipment to the production of internal combustion engine technology level and the international advanced level to shorten the gap; but the ability to further their own research and development is obviously inadequate, yet completely free from the introduction of a raise again and again improve the framework for the introduction again. According to China's current situation, technology development for the test problems,[link widoczny dla zalogowanych], on the future development of the following measures for reference. • Strengthening basic testing techniques and devices research and development, with particular attention to research and development of a precision instrument (sensor or transmitter), because many of the test system accuracy is mainly limited by the sensor accuracy. • Strengthen the digestion and absorption of imported technology, the second development, expand the application scope. To take full advantage of the introduction of technology and equipment, to strengthen research institutes, universities and professional manufacturer of cooperation, concentration of superior forces on the field of internal combustion engine testing urgent need to address the problem of joint research. According to national circumstances, developed a highly sophisticated products with Chinese characteristics. • The note made test equipment, instrumentation equipment, while the performance and functional development, with special attention to the reliability of protection, from the design,[link widoczny dla zalogowanych], prototype, technology, production, service and other aspects of strict control, the reliability of the formation of a domestic check standards, the only way to improve the credibility of the localization of instrumentation and market competitiveness. * Attention to the cultivation of internal combustion engine testing professionals, with special attention to training and a large number of new skills, comprehensive knowledge, electrical and mechanical Kanemichi and hardworking professional and technical personnel, at the same time to stress test the technical staff to update their knowledge. • Strengthening the internal combustion engine testing technology industry organization management and coordination role, and strive to make each other's needs. Complement each other, especially vigorous support to our professional factory special test equipment to enable them to truly become the backbone of our industry and leading the test, and only then will it be the cause of engine testing in the future. 5 Conclusion In the dawn of the 21st century, we face opportunities and challenges. How can the international advanced level as quickly as possible to shorten the gap between the internal combustion engine testing is still the large number of scientific and technical personnel in the future to be the goal. We should make full use of internal combustion engine of rapid industrial development at this stage the favorable opportunity, pay attention to the successful experience from abroad,[link widoczny dla zalogowanych], continue to follow the introduction and the road of combining self-development, and strive to make our engine testing technology in a short period of time with large leap.
