NO2 Emissions From Catalyzed DPF vs Uncatalyzed DPF/FBC System

(Engine Dyno Data)

150

Heavily Catalyzed Filters

100

NO2 (ppm)

50

Uncatalyzed DPF/FBC

Uncatalyzed DPF/FBC x 10

0

DPF = Diesel Particulate Filters FBC = Platinum/Cerium Fuel Borne Catalyst

25

Secondary Emissions Tests

  • No increase in 200 species

  • No ultra fine“oxide particle” peak

  • Engine out carbon is reduced 30 to 40 %

  • 95% Pt+Ce retained in engine, 99% in engine + filter

system if fitted

  • Dioxins and furans not affected by Pt +Ce

  • PAHs reduced by 95-97% (with Filters)

  • NOx reduced by 11%

  • No impact on NO2 emissions

  • CO & HC reduced by 60% - 70%
