HEI launches two new non-tailpipe particulate emission studies

Green Car Congress

The Health Effects Institute (HEI) has launched two new studies funded under RFA 21-1, Quantifying Real-World Impacts of Non-Tailpipe Particulate Matter Emissions. The new studies are: Improved Characterization of the Real-World Contributions and Impacts of Non-tailpipe Particulate Matter Emissions ,” led by Greg Evans, University of Toronto.

Study links exposure to diesel exhaust particles to pneumococcal disease susceptibility

Green Car Congress

Researchers from the University of Liverpool, Queen Mary University, London and Trinity College Dublin have linked exposure to diesel exhaust particles (DEPs) to susceptibility to pneumococcal disease. What we did not know however, was how pollution, such as diesel exhaust particles, actually causes airway disease.

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.

Study links ambient PM2.5 and ozone specifically caused by vehicle exhaust emissions to ~361,000 premature deaths worldwide in 2010 and ~385,000 in 2015

Green Car Congress

A new study provides the most detailed picture available to date of the global, regional, and local health impacts attributable to emissions from four transportation subsectors: on-road diesel vehicles; other on-road vehicles; shipping; and non-road mobile engines such as agricultural and construction equipment. of global ambient PM 2.5

Researchers show mechanism by which diesel exhaust particles trigger respiratory “flare-ups”

Green Car Congress

Researchers at Imperial College London, working with colleagues from King’s College London and University of British Columbia, have demonstrated a mechanism by which diesel exhaust particles directly affect the lungs to initiate symptoms such as a tightening of the airways and cough.

Hydrogen Opposed Piston Engine Working Group formed

Green Car Congress

—James Turner, Professor of Mechanical Engineering, Clean Combustion Research Center, King Abdullah University of Science and Technology (KAUST). The only criteria emission of concern is NO x. OP engines utilize direct injection after ports closure to avoid the risk of fuel short circuiting out the exhaust. Fuel Injection.
