It has passed the TUV certification of German Rhine and is now in mass production. Due to different principles, only diesel engines can break through 50% thermal efficiency now. However, the global average level is only 46%. It is not easy to increase every 0.1%. Moreover, it is very challenging to meet the national sixth emission standard in China. According to the report, Tan Xuguang, chairman of Weichai Holding Group Co., Ltd., is not only an engine technology expert who has been engaged in engine technology for 40 years, but also has invested more than 30 billion yuan in R & D in the past 10 years, bringing in more than 200 doctors, more than 300 global high-end talents and more than 3000 graduate students to challenge the core technology. In the end, Weichai has conquered the core technology of thermal efficiency, and created five kinds of advanced technologies, including collaborative combustion technology, coordinated design technology, exhaust energy distribution technology, partition lubrication technology and intelligent control technology. The five technologies have solved a series of world-class problems, such as high-efficiency combustion, low heat transfer, high reliability, low friction loss, low emission of pollutants, intelligent control and other world-class problems, making the thermal efficiency of diesel engine body more than 50%. At the same time, this breakthrough has also been recognized by domestic and foreign authoritative organizations, including Germany t Ü v South Germany group and China Automotive Technology Research Center Co., Ltd., China National Testing Agency for internal combustion engines, which have issued certification certificates to Weichai engines. < / P > < p > in addition, this technological breakthrough will not stay in the laboratory stage. It not only breaks through the 50% thermal efficiency, but also meets the national sixth emission standard. It has the conditions for mass production and commercialization, and is planning to mass production. Global Tech
