摘　　要：近几年,随着中国经济的飞快发展,中国民众对柴油车的需求量不断提高,柴油车尾气给环境带来的污染也日益加重。为此,国家针对尾气排放出台了国六B和非道路四阶段的法规。为了落实国六和非道路四阶段的法规实施,提出后处理连接结构的优化升级,减少后处理焊接工序的同时,提高后处理的机械性能。针对国六和非四后处理进行了调研和研究,对现有的后处理产品连接结构进行优化。In recent years,with the rapid development of China's economy,the demand for diesel cars in China has been increasing,and the pollution caused by diesel exhaust to the environment has been increasing.Therefore,the state has issued the national six B and non road four stage regulations for exhaust emissions.In order to implement the national six and non road four stage regulations,we propose the optimization and upgrading of the post-processing connection structure,which can reduce the post-processing welding process and improve the mechanical performance of the post-processing.We have carried out research and study on the national six and non four post-processing,and optimize the connection structure of the existing post-processing products.
