Study shows biodiesel blends in buses reduce PM, other harmful exhaust elements, EC and CO

Green Car Congress

The study, published by the Mineta National Transit Research Consortium (MNTRC), observed a reduction in amount of particulate matter, number of elements, and elemental carbon; the reduction is considered beneficial to promoting the clean air and human health. Ultra-low-sulfur diesel (ULSD) was used as base fuel. µg/m 3 , respectively.

U Birmingham study finds DPFs have limited impact on ultrafine particle emissions

Green Car Congress

A study by researchers at the University of Birmingham in the UK has found that while Diesel Oxidation Catalysts (DOCs) and Diesel Particle Filters (DPFs) has been very effective in controlling the tailpipe emissions of solid particles, there has been little change in the liquid mode ( 104 cm −3 /24-hour mean) defined by WHO.
