On November 20th, Professor Feng Huihua, Chairman of the Design and Intelligent Manufacturing Branch of China Internal Combustion Engine Society, led a team to Yuchai for a visit and communication, aiming to solve the problems encountered in the engine production process with the help of the theoretical knowledge of the branch in internal combustion engine design and intelligent manufacturing, break through the key technology of design and manufacturing, and realize the production, study and research. Promote the development of enterprises with advanced theories and technologies in universities.
In the morning, the team visited Yuchai Science and Technology Museum and engine production line. Yuchai Mo Qixing, deputy chief technology engineer of Yuchai, introduced Yuchai's development history, advanced engine technology, engine production line, etc., and discussed the main market and advanced engine technology of Yuchai at present. Then, Mo Qixing introduced Yuchai's advanced manufacturing technology, and put forward the main problems Yuchai faced in the engine manufacturing process, such as hydrogen embrittleness of hydrogen engine materials, emulsification of hydrogen engine lubricating oil, friction of valve seat ring, process big data application, engine factory abnormal noise detection, etc. In view of the above engine manufacturing process problems, the two sides launched a fierce discussion, and put forward some effective solutions.
In the afternoon, Benjie introduced Yuchai's innovation capability and 1235 strategy, and put forward the main problems faced in engine design, including: the correlation between 0.5 order noise and combustion parameters of diesel engines, the relationship between fuel economy and emissions, how to deal with domestic common rail system and do a good job in the future and long term planning. The participants of the branch offered suggestions for the problems raised by Yuchai, and reached a consensus on the solutions to some problems. Finally, Professor Feng Huihua said that the branch will maintain close contact with Yuchai to jointly overcome the problems faced in the process of engine design and manufacturing, and jointly support the sustainable development of clean and efficient internal combustion engine technology in the context of electrification
In the later stage, the branch will continue to strengthen cooperation and exchanges with Yuchai, continue visits between members of the branch, improve the influence of the activity in the internal combustion engine academia and industry, and aim to build the exchange activities of members and units into brand activities of the China Internal Combustion Engine Society, while improving the level of internal combustion engine design and manufacturing in China.
