exhaust system

With the rapid development, industrialization and specialization, the auto service market is appearing as the biggest attractive sector in China for domestic and international investors. Industry experts claim that China auto service industry will initiate a milestone starting point for its future robust growing. In China, the auto parts is 37％, manufacturers are 43％, retail is 8％ and service is 12％. The environment problems also accelerate the development of exhaust system industry. In the world market, the main forces driving the automotive exhaust systems industry are the emission and fuel economy targets. Exhaust suppliers are requested to support the carmakers to reach these targets and assure comfortable noise attenuation without over-design in order to guarantee a low system cost. Technical developments in the hot-end are highly influenced by the new emissions legislations such as the forthcoming Euro 5 in Europe. As a result, there is an emergence of new exhaust systems technologies for both diesel engines such as close-coupled diesel particulate filters, NOx traps, and clean exhaust gas regeneration.
