Two-year study in Canada finds large trucks disproportionately contribute to higher levels of black carbon pollution

Green Car Congress

A two-year study led by researchers at the University of Toronto has found large trucks to be the greatest contributors to black carbon emissions close to major roadways. Research consistently links traffic emissions to negative effects on both the environment and human health. Jonathan M. Shairsingh, Robert M. 8b01914.

SwRI engineers develop near-zero emissions diesel engine technology; 90% reduction of NOx

Green Car Congress

Southwest Research Institute engineers have developed the next generation of clean diesel engine technology to reduce hazardous nitrogen oxides (NO x ) and carbon dioxide emissions while minimizing fuel consumption. According to the Environmental Protection Agency, nitrogen oxides are harmful to human health and the environment.

Greyrock, NREL study determines reduction in GHG and criteria pollutant emissions from using synthetic fuels produced from flare gas

Green Car Congress

A “well-to-wheel” life cycle assessment (LCA) by a team from synthetic fuels producer Greyrock ( earlier post ), and the National Renewable Energy Laboratory (NREL) has determined the potential reduction of greenhouse gases and criteria pollutant emissions from the use of synthetic fuels directly converted from flare gas. billion liters (18.8

T&E: tests show cars powered by electrofuels emit high levels of criteria pollutants

Green Car Congress

E-fuels are made by combining green hydrogen with CO 2 to produce liquid fuel that can be similar to gasoline or diesel used in conventional engines (as well as kerosene used in aviation). However, said T&E, particle pollution was far from eliminated. Carbon monoxide emissions were much higher with the e-gasoline blends tested.

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: curbing diesel emissions could reduce mortality rates in big cities

Green Car Congress

Freight transportation is a pillar of the US national economy, but while long-haul trucks account for less than 6% of the vehicle miles traveled over US highways, they account for about 40% of the emissions of air polluting particulate matter and about 55% of nitrogen oxides, the precursor to ozone in the atmosphere, the study said.
