Valin's two provincial-level scientific and technological research projects on the engine passed the acceptance test

On July 6, 2018, commissioned by the Science and Technology Department of Anhui Province, the Maanshan Science and Technology Bureau organized experts to invest in the development of 12L high-efficiency energy-saving natural gas engines (project number) and “diesel methanol” for two provincial science and technology projects undertaken by Valin. "Double fuel country five engine technology research and development" (project number: 1604a0902143) was accepted. Four well-known technical experts and two well-known financial experts from domestic universities, research institutes and accounting firms were invited to serve as members of the acceptance team. The leader of the acceptance expert group was appointed by the Executive Vice President of the Anhui Machinery Federation and the Vice President of the Anhui Machinery Industry Association, Mr. Feng Yidong. Deputy Director Song Bing of Maanshan Science and Technology Bureau presided over the project acceptance meeting. Director of the Project Management Center of Anhui Science and Technology Research Institute, Sun Fei, Deputy Director Chen Liang and leaders of relevant departments of Maanshan Science and Technology Bureau attended the conference. Chairman of the group company Liu Hanru, general manager of the engine branch Wang Xiangzhi, director of the engine research institute Lu Lin and other leaders and project team members attended the meeting.

During the acceptance process, the project team members made detailed reports on the work of the two projects, the main research contents, the technical research indicators achieved, the economic benefits realized, the application opinions and the use of funds. The expert group carefully reviewed the work. Relevant technical documents examined the R&D, production site and results. After questioning and full discussion, the expert group believes that the “12L high-efficiency energy-saving natural gas engine development” and “Diesel methanol dual-fuel national five engine technology research and development” undertaken by Anhui Hualing Automobile Co., Ltd. have completed the contract regulations. The various tasks and indicators, special funds for special funds, unanimously agreed to pass the project acceptance. At the same time, the participating experts pointed out the shortcomings, weak links and improvement directions in the project implementation process according to the actual situation of the project, and made valuable suggestions from the aspects of developing new products, attaching importance to patent protection, and strengthening cooperation between industry, universities and research institutes.

The "12L high-efficiency energy-saving and environmentally-friendly natural gas engine development" project completed the research, design, development and verification of the product according to the forward development process. The series of engine structures adopts in-line 6-cylinder, integral cylinder head and four-valve, and adopts electronically controlled gas injection system. It meets the national five emission standards and has the advantages of low speed, high torque, energy saving, environmental protection, safety and reliability. The series of products have passed the compulsory inspection of the National Quality Supervision and Inspection Center (Chongqing) and have achieved mass production with good economic and social benefits.

“Diesel methanol dual fuel national five engine technology research and development” is based on self-developed diesel-methanol dual-fuel mixed combustion technology, comprehensive application of exhaust gas recirculation and self-owned brand exhaust gas after-treatment technology, the product meets the national five emission standards, methanol blending rate can reach 44.3 %, effectively reducing diesel consumption. The research and development of the dual fuel DMCC engine calibration strategy, the development of the calibration software and test verification, the establishment of a dual fuel engine test verification and calibration system. The series products have passed the inspection of the National Car Quality Supervision and Inspection Center (Tianjin) and have the ability to mass production.

Through the implementation of the two projects, the company's product structure has been continuously adjusted, which has cultivated a new important economic growth point for Valin, and promoted the company's sustainable development. At the same time, it also enhances the research and development confidence of the company's scientific research personnel, and will play an active role in promoting the company's research and development capabilities and level. The successful completion of the project has greatly promoted the technological progress of China's heavy-duty engine industry and related enterprises, and has driven the development of upstream and downstream industries.
