Exhaust emission characteristics for LPG/CNG automobiles:
In addition to CO, and NOx, the HC ‘s main component is CH4,while CH4 is the most stable compound. The coupling reactions of CH4 and NOx is more difficult than the HC and NOx coupling, resulting in difficulty of NOx conversion; meanwhile, CH4 is difficult in oxidized, gasoline exhaust purifying exhaust catalyst can not be used on CNG vehicles purification. For CNG vehicle exhaust gas purification characteristics, the company has developed a catalytic material suitable for CNG vehicle exhaust catalysts, achieving IV / V emission standards and higher autocatalyst, obtaining excellent activity and durability.
Threeway series of CNG/PLG car catalyst meet Euro IV, Euro V emission standard, and has been successfully used on many types of vehicles boasting for low Ignition temperature and good anti-aging properties.
