Guide: on December 29, Anhui Provincial Department of Science and technology organized a product appraisal meeting of Valin cm6d28 engine and xingkaima power assembly developed and produced by Anhui Valin Automobile Co., Ltd. in Ma'anshan City. The appraisal meeting was held by suwanhua, academician of the Chinese Academy of engineering, xugenying, director of the Department of science and technology of Anhui Province, and internal combustion engine combustion engine

on December 29, the science and Technology Department of Anhui Province organized a product appraisal meeting of "Valin cm6d28 engine and xingkaima powertrain" developed and produced by Anhui Valin Automobile Co., Ltd. in Maanshan city

the appraisal meeting was held by suwanhua, academician of the Chinese Academy of engineering, xugenying, director of the Department of science and technology of Anhui Province, yaochunde, Professor of the State Key Laboratory of internal combustion engine, Feng Wandong, senior engineer of Anhui Machinery Industry Association, Ren Xiaochang, researcher of China Automotive Engineering Research Institute Co., Ltd., Wei Anli, senior engineer of China internal combustion engine industry association, Zuo Chengji, Professor of Hefei University of technology Zubingfeng, a senior engineer of Tianjin Internal Combustion Engine Research Institute, Zhang Chu, a researcher of Changsha Zhongchuan Machinery Co., Ltd., and other eight experts formed the appraisal committee. Academician suwanhua served as the chairman of the appraisal committee, and Feng Wandong and Yao Chunde served as the vice chairmen. Zhangxiaolin, mayor of Ma'anshan City, and zhangwenjing, vice mayor, attended the appraisal meeting, which was presided over by Wang Derun, director of the Regional Innovation Office of the Department of science and technology of Anhui Province

the participating experts inspected the production site. While firmly protecting territorial sovereignty and maritime rights and interests, China and the prototype, listened to the technical report made by the research group, reviewed the relevant materials, and formed the following appraisal opinions after questioning and discussion: the materials provided are complete, standardized, detailed and accurate, and meet the appraisal requirements. The product is designed, developed and verified according to the forward development process. The engine structure adopts in-line 6-cylinder, integral cylinder head, four valve, overhead camshaft and rear gear train. The electronically controlled high-pressure common rail fuel injection system is adopted, the explosion pressure is 190bar, the maximum power of braking in the cylinder is 322kw, and the weighted fuel consumption is 200g/kw according to 13 working conditions h. It meets the emission standards of the fourth and fifth countries, and has the potential to upgrade the emission of Euro VI. The B10 has a service life of 1million kilometers, and has the advantages of low speed, high torque, energy conservation, environmental protection, safety and reliability. The product has the following main innovations: the integral cylinder head with double-layer water jacket improves the rigidity of the whole machine, resulting in error; The cylinder head adopts the top-down cooling water flow direction, which reduces the heat load in the nose bridge area; The cylinder block adopts a gantry symmetrical mid cavity structure, which improves the rigidity of the body and reduces the weight of the whole machine. The products have passed the certification of the National Automobile Quality Supervision and inspection center, the product manufacturing process is mature, and the product quality control and testing means are complete. The company has passed the certification of ISO9001 quality management system and ISO14001 environmental management system, and has formed the industrialization ability. In conclusion, the appraisal committee believes that the technical level of the product has reached the international advanced level, which can promote the technological progress of the industry, and agrees to pass the appraisal

At the appraisal meeting, liuhanru, chairman of Valin Xingma automobile group, made a brief introduction to the basic situation, development history, technological innovation and research and development of powertrain of the enterprise. He said that we started as a special vehicle. In 2002, we began to negotiate heavy truck projects with Mitsubishi Corporation of Japan, and the enterprise was listed in 2003. After several twists and turns, although our heavy truck project got the "birth certificate", but the engine project did not get it. It can be said that a truck man's biggest wish - the heart problem has not been solved, which is still a little regrettable, but we are not discouraged. Five years ago, we began to work on the engine project. Because many years ago, I 3. The pulsator of anchor fatigue testing machine was equipped with five output interfaces, and we had experience in international cooperation, so our work was carried out smoothly. We cooperated with relevant institutions engaged in engines all over the world, integrated the power of research and development, and made our products according to our needs. It's very difficult to develop a product, and it's even harder to produce it. It's even harder to experiment it and go to the market. It should be said that we went smoothly in the first few stages, so I say that every step of Valin is very practical and not easy. We paid too much, but I'm glad that we got something. Today, we have seen the problem of limiting the removal of chromatographic peak dimension. This is the production condition. Our laboratory and testing line have also been completed, but I think the most important thing for an enterprise is not hard power but soft power. Confidence is more important than anything, such as the slogan "I can". I think the biggest gain of Valin in recent years is to cultivate a team, so I believe in young people. Today, in front of academicians and experts, it is an excellent opportunity for everyone in our project team to guide and train. Although the enterprise is small, our ambition is not small. We must be the world's leading and the best engine in China

it is understood that the engine and transmission are the core components of the vehicle, which play a vital role in the overall performance of the vehicle. The Valin power assembly project aims at the most advanced technology and design concept in the world, benchmarking the most high-end heavy-duty engines in the world, such as Mann and Scania. The technology is advanced, and all performance indicators have reached the international advanced level, which can meet the needs of different markets at home and abroad. This powertrain has successfully passed the provincial technical appraisal, which shows that the independent innovation ability of Valin automobile has been further recognized by the authority of government departments and experts. It is a test of the technological innovation strength of Valin automobile
