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

Green Car Congress

Created to address California’s pollution challenges, this technology could be a solution for communities around the globe dealing with the effects of NO x. The State of California plans to enact tighter emissions standards in 2024 and will require that heavy-duty engines produce less pollutants.

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

Exhaust from on-road diesel vehicles was responsible for nearly half of the impacts (~181,000 premature deaths) worldwide, and fully two-thirds in India, France, Germany, and Italy. The distribution of health impacts and air pollution from transportation is influenced by policy, demographic, economic, and technological changes.

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.

Researchers develop effective exhaust catalyst for lower temperature exhaust

Green Car Congress

To improve fuel efficiency, advanced combustion engines are being designed to minimize the amount of waste heat in the exhaust. As a result, future generations of exhaust after-treatment catalysts must perform at temperatures that are 100 °C lower than current catalysts. —Nie et al. Resources.

UNFI adding 53 all-electric TRUs to California fleet

Green Car Congress

By operating the all-electric TRUs, UNFI anticipates it will save approximately 135,000 gallons of diesel fuel per year while reducing particulate matter pollutant emissions and greenhouse gas emissions. Nearly 50 percent of UNFI’s direct greenhouse gas emissions are from our fleet of trucks and trailers.

UK ONS report finds significant challenge remains to reduce road transport emissions; sector GHG emissions up 6% from 1990-2017

Green Car Congress

A new report by the UK’s Office for National Statistics (ONS) finds that greenhouse gas (GHG) emissions from road transport in the UK rose by 6% from 1990 to 2017. Total fuel used for road transport in the UK remained relatively stable from 1990 to 2017 as the fuel efficiency of newer vehicles has improved.

ICCT life-cycle analysis finds no climate benefit in using LNG as marine fuel

Green Car Congress

Additionally, LNG engines are tuned to either emit low nitrogen oxide (NO x ) emissions—at the cost of higher methane emissions in some cases—or to incorporate NO x reduction technologies such as exhaust gas recirculation (EGR) or selective catalytic reduction (SCR). 2017) that actual ship operations are different.
