According to the management committee of Beihai High-tech Zone, the “industrial demonstration project of diesel engine SCR catalyst †independently developed by the company Beihai Huihuang Langjie Environmental Protection Technology Co., Ltd. was recently awarded the 2012 Torch Plan of the Ministry of Science and Technology. This is also the first time Guangxi enterprises have won this honor in this field. The project applies high-efficiency rare-earth technology to the purification of automobile exhaust gas. Tests show that the catalytic conversion efficiency of automobile exhaust gas can reach over 97%, and the pollution index can meet the national IV emission standard, which is close to zero emission, and its technology has reached the international advanced level. The domestic production gap. At present, the product has successfully assembled Beijing Bus and is matched with engine manufacturers. At the same time, it cooperates with many domestic engine manufacturers such as Yuchai, Weichai, and Dongfeng Cummins . After the product is put into mass production, it will break the pattern of China's diesel engine SCR automotive exhaust catalysts relying on foreign imports, and greatly reduce the cost of tail gas purification in the automotive industry. To obtain perfect joins, inside of the solder ring copper fitting and the outside of the copper pipe are cleaned using coarse steel wool, flux paste is applied, the pipe is then inserted into the fitting and heat applied from a portable propane torch until a ring of solder shows at the edges of the fitting.
