CNG Natural Gas Exhaust Catalyst Ceramic Substrate Euro 4/5/6
CNG(Natural Gas Exhaust Catalyst)
CNG technical route:
1. A single gaseous fuel directly uses TWC catalyst. Considering the increase of NH3 emission requirements in the regulations, ASC catalyst can be added in the later stage.
2. Dual-fuel engines need to consider two fuel types, so DOC is switched to TWC catalyst, which mainly needs to deal with CH4 pollutants, and also has the function of DOC.

Product introduction:
CNG catalyst can efficiently convert harmful hydrocarbons (HC, mainly CH4), carbon monoxide (CO) and nitrogen oxides (NOx) in the exhaust gas of natural gas vehicles into harmless water (H2O), carbon dioxide (CO2) and nitrogen (N2) through oxidation-reduction reactions.
Product advantages:
With nearly 20 years of technology accumulation, we can provide customers with rich customized solutions. CNG catalyst can meet Euro-VI and China-VI regulations. CNG catalyst has been mass produced and successfully applied on more than 50 different domestic and foreign engine projects meeting China-VI emission standard.
