1.Constitute Catalytic muffler is a integrated catalytic muffler, which is composed of catalytic converter and catalytic muffler .And it is our patent product . Generally it is consists of three parts. They are ceramic honeycomb catalyst ( or a metal honeycomb catalyst ) , metal house and muffler. In addition to have the features of catalytic converter, integrated catalytic muffler also reduce the noise well. The silencing effect is about ≥25 (1L / dB (A)).
Catalytic muffler is our new product . It is mainly consist of housing and closed chamber with front cover and back cover. On the front of chamber install a inlet air pipe. And on the back-end install a exhaust pipe. There is a catalytic processing equipment in the shell. This equipment is make up of 2-5 catalytic filter which was segregated every adjoined two filter on the same axle.And there are two checking ring which located in the leading end and back-end respectively.
Internal combustion engine muffler, the target of silencing of noise are emissions from engine. Its features are small flow ,high flow rate, high temperature , high oil contamination and so on. Internal combustion engine muffler poor working conditions , it will bear to shock of high temperatures and high flow. So we have high demanding to the performance of internal combustion engine muffler for practical use. In addition to higher volume muffler , we special attention to the hydrodynamic performance of the muffler and strict volume restrictions.The resistance of the muffler is very sensitive to the reaction of internal combustion engine . If the muffler is not installed well, the engine operating condition will be worsen. For example, reduc the efficiency,increase consumption and improve exhaust gas temperature. Therefore, internal combustion engine muffler is a muffler with highly technical.
3.Company production of integrated catalytic muffler model of LNG and emissions standards are:
According to customer needs, we can make different size catalytic converter . We also can meet the standard of Euro III , Euro IV , Euro V .
