On January 18, 2013, the CPC Central Committee and the State Council held the 2012 National Science and Technology Awards Conference in the Great Hall of the People in Beijing. This time, it awarded 2 national top science and technology awards, 41 national natural science award second prize projects, 77 national technical invention award projects, and 212 national science and technology progress award projects. Yuchai ’s “Key Technology and Industrialization of Energy-saving and Environment-friendly Diesel Engines †project won the second prize of the National Science and Technology Progress Award. Yuchai, the chief engineer of Yuchai Group and the first completioner of the project, received the prize on behalf of Yuchai. This is Yuchai's first national science and technology progress award .
As the largest internal combustion engine production base in China, Yuchai Group established the special project of “Key Technology and Industrialization of Energy-saving and Environment-friendly Diesel Engines†under the dual mission of social responsibility and the development of national brand enterprises, striving to break through energy-saving and environment-friendly diesel engines. The key technologies include lightweight, high-strength structural design, high-efficiency in-cylinder combustion technology, precision-controlled electronically controlled high-pressure fuel injection technology, and clean exhaust emission control technology, which have been developed to meet China's national conditions and achieve international standards. Energy-saving and environment-friendly new type diesel engine. After nearly a decade of hard work, this project has achieved breakthroughs in the development of core technology platforms such as diesel engine structural design, combustion development, emission control, and electronic control, and achieved its intended goals.
Since 2005, engine products that use the technical achievements of this project have begun to be put on the market in batches, and are widely used in more than 100 mainstream models of mainstream automobile factories in the country. Looking at the key technological achievements of this project, compared with the technical gap of 8 to 10 years before the project was established, Yuchai’s current energy-saving and environment-friendly key technologies have significantly shortened the gap with foreign technologies and led domestic counterparts. The combustion and emission control technologies have basically reached the international advanced level, and the power density, thermal efficiency, and B10 life have fully reached the international advanced level.
