HEI ACES study of lifetime animal exposure to New Technology Diesel Engine exhaust finds no lung cancer

Green Car Congress

The first study to conduct a comprehensive evaluation of lifetime exposure to new technology diesel exhaust (NTDE)—i.e., exhaust from heavy-duty diesel engines meeting EPA 2007 and later emissions requirements—has found no evidence of carcinogenic lung tumors. This phase was conducted at SwRI in 2012.

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

Green Car Congress

Additional diesel PM reductions in 18 major CA railyards with five new locomotive measures. While we are pleased to have already reduced diesel emissions at the rail yards, it’s not enough.

Why Electric Buses Are the Healthy School Choice

Blink Charging

Why electric school buses are needed The best reason to switch from ICE school buses to electric school buses can be summed up in just two words: child wellness. Many school districts use diesel buses for fuel efficiency, but even diesel exhaust was classified as a known carcinogen to humans in 2012.

PNNL team finds correlation between reaction mechanism for zeolite SCR catalyst for NOx aftertreatment and bacterial enzyme catalysis

Green Car Congress

A team of researchers in the Institute for Integrated Catalysis at Pacific Northwest National Laboratory led by chemist János Szanyi has proposed a reaction mechanism for a highly active zeolite catalyst (Cu-SSZ-13) used in selective catalytic reduction (SCR) NO x aftertreatment systems for diesel emissions.

Berkeley study identifies diesel as main source of vehicular secondary organic aerosols

Green Car Congress

Contribution of gasoline and diesel exhaust to SOA over 0% to 50% diesel fuel use. SOA contributions from the two sources are equivalent at 6% diesel fuel use. These compounds in un-burned gasoline and diesel fuel dominate vehicular emissions of reactive gas-phase carbon that have the potential to form SOA.

National Academies release third review of the 21st Century Truck Partnership

Green Car Congress

The National Academies have released a third review of the 21 st Century Truck Partnership (21CTP); the review follows the Phase 1 and Phase 2 reviews by the National Research Council in 2008 and 2012 ( earlier post ) and assesses the progress the partnership has made. If necessary, the next-generation code development should be adjusted.

Comparative study finds that B20 increases emission rates of a number of pollutants in both light- and medium-duty diesel engines at idle

Green Car Congress

L) diesel engines at idle and load, using a biodiesel blend (B20) and conventional ultralow sulfur diesel (ULSD) fuel. They found that the level of emissions of regulated and unregulated pollutants in diesel exhaust depends on fuel, load, engine calibration, and exhaust aftertreatment technology.
