Study finds that diesel school bus emission retrofits reduce tailpipe emissions, but dont do much for pollution in passenger cabin

Green Car Congress

A UCLA study of the performance of retrofit systems for diesel-powered school buses has found that while the systems significantly lowered tailpipe emissions, there was no unequivocal decrease for in-cabin air pollutants after retrofitting.

New nanostructured earth abundant metal catalysts rival platinum on a weight basis; diesel emissions treatment

Green Car Congress

A development in catalysis research by academics at the Universities of St Andrews and Newcastle could lead to new systems to treat diesel emissions. Catalysts are typically metallic nanoparticles—often platinum group metals—that are finely deposited upon a substrate. Dragos Neagu, Evangelos I. Irvine & Ian S.
