On August 22nd, the three 863 projects “Scientific Research and Development of Diesel Engines for Small and Medium Sized Agricultural Machinery and Construction Machinery†led by FAW Wuxi Fuel Pumps Yuzu Institute, Changchai, and Shanghai Internal Combustion Engine Research Institute successfully passed the national level of the expert group of the Ministry of Science and Technology. acceptance. These achievements have not only promoted the core competitiveness of China's fuel injection pump companies in terms of independent design and manufacturing, but also marked the overall “upgrading†of China’s non-road medium- and small-displacement single-cylinder and four-cylinder diesel engines.
At present, European and American non-road diesel engines have begun to implement Euro III emission standards, and China's emission levels are equivalent to Euro II. The “Eleventh Five-Year†National 863 Program Major Projects in the Advanced Manufacturing Technology Field “The Research and Development of Diesel Engines for Small and Medium-Sized Agricultural Machinery and Construction Machinery†aims to promote the low emission of non-road diesel engine industry in China through the study of key diesel engine technologies. The overall improvement of technology breakthroughs. After two years of research, the research group of Wuxi Pumps made a breakthrough in how to improve the design of fuel system with high injection pressure and governor control capability. It has obtained a number of invention patents and formed a brand-new independent development design. The concept explored an independent high-pressure injection pressure fuel system manufacturing process, formed a complete set of manufacturing process specifications and standards, and successfully developed key technologies and products for high-pressure fuel injection pumps applicable to “new generation†non-road medium- and small-displacement diesel engines. "Successfully completed the research tasks stipulated by the project. In particular, the non-road four-cylinder diesel engine using the research results of Wuxi Pumps successfully passed the national Euro III test, making China's independent innovation of the economic high-pressure direct injection “SARS†route on the EU III emission technology route a “typical model†suited to China’s national conditions. "route. This is the result of the research and development of high-pressure direct injection technology after the FAW Wuxi Fuel Injection Equipment Research Institute inherited its own electronically-controlled common-rail technology. This completely breaks the myth that multinational companies must adopt electronically-controlled common rail emission.
It is understood that Wuxi Pump Research Group applied for 5 patents in the process of project development and formulated 3 national standards and 16 industrial standards. The research results have been widely used in Shandong Longkou Long Pump and other domestic oil pump nozzle factory. The products have been implemented in the domestic mainstream diesel engine companies Yuchai, Quanchai, Xichai, Weichai, Changchai, Changfa, and the product will become more satisfied. High emission non-road diesel fuel injection pump is the main product. In the process of project development, a group of core talents with doctoral or master's degrees were trained to achieve the goals of “out thinking, method, technology, process, product, product, standard, and talentâ€.
