New statistical method to detect ozone pollution hot spots and monitor instrument failure; combining PCA and MEWMA

Green Car Congress

A new statistical method developed by researchers at KAUST (King Abdullah University of Science and Technology, Saudi Arabia) can detect abnormal ozone levels within large bodies of monitored data. The monitoring methods can quickly and accurately detect ozone anomalies—localized spikes in ozone concentration indicated by sensor data.

The importance of considering non-exhaust traffic emissions; the role of EVs

Green Car Congress

the criteria pollutants and CO 2 that emerge with the exhaust from the tailpipe. However, there is more than 15 years of research showing that the contribution of non-exhaust primary particles to the total traffic generated primary particles is significant in urban areas. Further, a 2013 review by Denier van der Gon et al. Background.

The rail sector is the only transportation modality without significant emissions related development that is feasible in the near-term to eliminate ozone, smog and GHG emissions, OptiFuel says. g/bhp-hr of NOx, a reduction of 400 times. More than 122 million people (nearly 40% of the U.S. In 2018, Class I, II, and III railroads purchased 4.7

CARB releases results of multi-year E15 study; multiple air quality benefits with slight reduction in fuel economy

Green Car Congress

The California Air Resources Board (CARB) has released the results of a multiyear study evaluating exhaust emissions from the use of California Reformulated Gasoline (CaRFG) that contains 15 volume percent ethanol (E15). California currently limits the ethanol content of gasoline to 10 percent. The study used two fuels—an E10 and E15.

Imaging study: air pollution impairs function of blood vessels in lungs

Green Car Congress

Air pollution impairs the function of blood vessels in the lungs, according to a study of more than 16,000 patients presented at EuroEcho-Imaging 2016. The volunteers were exposed to ambient air or dilute diesel exhaust with a PM 2.5 and ozone on pulmonary circulation on the same day and over five and ten days.

Study finds fleet switch from PFI to GDI engines will result in net reduction in global warming

Green Car Congress

As a result, the market share of GDI-equipped vehicles has increased dramatically over the past decade and is expected to reach 50% of new gasoline vehicles sold in 2016. We estimate ozone and SOA formation potential. We use the data to quantify the effects of engine technology, emission standards, and cold-start on emissions.

California ARB Seeks Further Reductions of Diesel Emissions at State Rail Yards

Green Car Congress

The top set of recommendations call for: Replacing existing switch and medium horsepower locomotives with cleaner locomotives (2010-2013); Retrofitting switch and medium horsepower locomotive with particulate matter and oxides of nitrogen (NO x ) after-treatment devices (2012-2016); and. NO x helps create ground-level ozone, or smog.
