Virginia Tech team developing intelligent wearable analyzer for pollutants in transportation-related workplaces

Green Car Congress

According to Agah, a renowned researcher in chip-scale gas chromatography and Office of the Vice President for Research and Innovation Faculty Fellow, the development of effective strategies for reducing occupational exposure to pollutants requires accurate, time-resolved measurement of exposure.

In a high-temperature environment, any fuel will behave like diesel fuel, having short ignition delay and burning as it is injected in a mixing fuel plume. Low-sooting fuels allow for the elimination of diesel particulate filtration (DPF). emissions significantly, while lowering criteria pollutants: particulate matter (soot) and NO x.

International consortium working on new sensor technology to measure real-world, in-use vehicle emissions

Green Car Congress

As part of the Horizon 2020 research project CARES (City Air Remote Emission Sensing), an international research consortium is working on new contactless exhaust measurement methods that will enable municipalities to take emission-reducing measures. The aim is to detect the exhaust class of each individual vehicle using these measurements.

DOE awards $35M to 12 ARPA-E projects to reduce methane emissions; 5 on natural gas engines

Green Car Congress

The project team’s technology will consist of a novel methane oxidation catalyst (MOC) formulation capable of high conversion efficiencies at the lower exhaust temperatures in ultra-lean burn engines. Typical MOCs have diminished methane conversion efficiency at low temperatures, limiting their synergies with ultra-lean burn NG engines.

UNECE: claim that diesel on-road vehicles are the cause of increased lung cancer is misleading

Green Car Congress

The claim that emissions from diesel engine exhausts from road transport are the main cause of lung cancer in humans thus “ needs to be seriously challenged, ” the paper concluded. —“Diesel Engines Exhausts: Myths and Realities”. Thus to improve the quality of air around us more attention must be given to the primary PM emitters.

Study Finds Controlling Soot May Be Fastest Method to Reduce Arctic Ice Loss and Global Warming; Second-Leading Cause of Global Warming After CO2

Green Car Congress

Jacobson used a computer model of global climate, air pollution and weather that he developed over the last 20 years and updated to include additional atmospheric processes to analyze how soot can heat clouds, snow and ice. Particle traps filter out soot particles from exhaust fumes. Mark Jacobson. Dessler et al., Guenther et al.,

DOE to award $7M to accelerate fuel and engine co-optimization technologies; Co-Optima initiative

Green Car Congress

Groundbreaking research in the last 10 years has identified combustion engine strategies that—especially if optimized to run on new fuels—would offer significantly higher efficiency and produce fewer engine-out pollutants than current engines. Fuel research will focus on low-GHG advanced biofuel/petroleum blends.
