GPF (Gasoline Particulate Filter)Euro 6 PN Filtration for After-treatment System
GPF (Gasoline Particulate Filter)
To meet Euro 6 / China-VI stage light-duty vehicles PN emission requirements, WFEC developed WFG series cGPF catalysts. WFEC cGPF catalysts can achieve excellent PN filtration rate through optimized washcoat design and distribution. By improve of washcoat material and coating process, the backpressure of cGPF catalyst is largely decreased, thus the negative influence on engine fuel economy by cGPF is obvious lowered. And the active catalytic washcoat on cGPF can deeply purify gas pollutant (such as THC, CO and NOx) and fulfill Euro 6 / China-VI aging requirements. cGPF can install in CC (Close-coupled) or UF (Under-floor) position, applying together with TWC. The vehicle emission of PN and gas pollutant is able to completely satisfy Euro 6 / China-VI regulations after employing WFEC TWC+cGPF aftertreatment system.
