on January 8, 2017 National Science and technology award conference was held in the Great Hall of the people, Yuchai participated in the projects of "rapid detection and evaluation technology and application of internal combustion engine airflow" and "manufacturing method and equipment of Dieless composite forming of complex castings", which won the second prize of the National Technological Invention Award, and the project of "development and industrialization of key technologies of new generation ultra-low emission heavy commercial diesel engine" won the second prize of the national science and technology progress award

award certificate

the project "rapid detection and evaluation technology and application of internal combustion engine airflow" has overcome the three major problems of airflow evaluation technology, airflow design technology and airflow consistency control technology, and opened up a new technology path of efficient and clean combustion of internal combustion engine dominated by airflow. The project was jointly completed by Tianjin University, Yuchai shares and Dalian University of technology when resources were relatively tight

the research of the project "manufacturing methods and equipment for dieless composite forming of complex castings" lasted for 10 years, breaking through the key technologies of high efficiency, high performance and high-precision dieless forming of complex castings, "Dr. Hou Shifeng said. Great achievements have been made in terms of process methods, composite molds, system equipment, etc., and it has realized that during the scraping of complex castings, attention should be paid to three taboos, one taboo, uneven force, and other ways to purchase 45 high-temperature motor car components without molding, high precision High efficiency manufacturing greatly shortens the manufacturing cycle, improves the casting quality and reduces the cost. The project was jointly completed by the General Academy of Mechanical Sciences, Yuchai and other units

the project "development and industrialization of key technologies of new generation ultra-low emission heavy duty commercial diesel engine" has achieved high efficiency and low emission in the whole working condition range by adopting efficient cooling exhaust gas recirculation (EGR) air system and advanced low emission combustion system, so that the effective thermal efficiency of the engine is close to the high level of 45%. The project was jointly completed by Tianjin University, Yuchai and other units
