SAE Publishes HARC Research on Engine Emissions
Conventional diesel engine exhaust aftertreatment systems are effective for reducing pollutants with the use of catalysts, similar to the catalytic converters used on vehicles. However, these catalytic systems are generally not effective at eliminating NCM.
HARC scientists developed and tested improved catalysts specifically designed to address NCM. While many catalytic systems use precious metals, the catalyst formulations tested in this work were made with common lower-cost metals including copper, nickel, and cobalt. Experimental results indicated improved reduction of NCM.
HARC Research Associate Dr. Fanxu Meng will present a paper co-authored with other HARC scientists on the findings of this work at the Society of Automotive Engineers World Congress in Detroit, Michigan in April. The paper entitled “Conversion of Exhaust Gases from Dual-Fuel (Natural Gas-Diesel) Engine under Ni-Co-Cu/ZSM-5 Catalysts” can be downloaded from SAE International at http://papers.sae.org/2017-01-0908/.
