Study finds diesel oxidation catalyst eliminates mutagenicity of diesel exhaust in gas phase

Green Car Congress

A team of researchers in Germany has found that the mutagenicity of diesel engine exhaust (DEE) is eliminated in the gas phase by a Diesel Oxidation Catalyst (DOC), but only slightly reduced in the particle phase. Further investigations showed that condensates of the gas phase are likewise mutagenic.

Researchers propose low-temperature SOFC unit for reducing NOx and oxidizing HCs in lean-burn engine exhaust

Green Car Congress

Their SOFC system can be operated without consuming the anode fuel (a reductant) at temperatures near that of the engine exhaust to eliminate the need for reductant refilling and extra heating. The NO x concentration in the exhaust of an automotive gasoline engine with spark ignition can be as high as 4000 ppm. —Huang et al.
