This product can be directly oxidized and decomposed the diesel engine exhaust particulate matter (PM). Compared to the conventional platinum catalyst , since the NOx catalyst without passing through the DOC conversion NO2, thus reducing the amount of expensive platinum , lower cost , and can obtain the same decomposition performance at lower temperatures, and in temperature can be increased at the same rate of decomposition .
It can also improve the combustion performance to the number of PM 's calculations , can reach more than 90% removal efficiency . GXLJ™ DPF and DOC units are proudly designed and manufactured , backed by outstanding warranty coverage and meet all Euro emissions standards.
Easy Installation. Exceptional Durability. Optimum Performance.
Ceramic DOC technology with Zeolites designed to extend the performance of diesel catalytic converters into the low temperature rangeMaintenance-free, reliable and cost-effective emission control solutionAvailable in both universal and direct-fit designs (GXLJ Technologies has a database of over 1000 direct-fit muffler designs)Mufflers are built entirely from corrosion resistant materials: aluminized and stainless steelsInstallation time and cost are reduced to a minimumDOC Catalytic Mufflers match or surpass the original muffler in sound attenuation and back pressure characteristics with addition of superior emissions performanceGreat at reducing deadly emissions,such as Carbon Monoxide(CO) and Hydrocarbons(HC)
We can make customized catalytic converter to meet customers' demand.
