Transient Plasma Systems says advances are bringing plasma ignition technology closer to commercialization

Green Car Congress

Advanced ignition technologies, such as those offered by TPS, have been widely recognized as enablers to achieving higher combustion efficiency and lower emissions for gasoline-powered engines. We believe the nanosecond pulsed power technology from TPS is unique and can be applied across a wide variety of applications.

Study finds that current approach to limiting wintertime pollution may initially backfire

Green Car Congress

The processes that create ozone pollution in the summer can also trigger the formation of wintertime air pollution, according to a new study from researchers at the University of Colorado Boulder and NOAA, in partnership with the University of Utah. To combat wintertime PM 2.5

HEI launches two new non-tailpipe particulate emission studies

Green Car Congress

Emissions from automobile exhaust systems have decreased in recent years due to the introduction of cleaner fuels and new control technologies on internal combustion engines, as well as increases in numbers of hybrid and electric vehicles.

UC Berkeley study confirms that yes, EVs do what they promise to do

Baua Electric

A new study from UC Berkeley confirms what EV fans already know: EV adoption does, in fact, make the air cleaner. Researchers from the University of California, Berkeley , found that between 2018 and 2022, CO2 emission from all sources (industries, homes, traffic) across the San Francisco Bay Area dropped around 1.8%

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., The study exposed laboratory rats 80 hours a week, for up to 30 months, to emissions from a heavy-duty diesel engine meeting 2007 US EPA standards using new filters and other control technology.

Study finds power law scaling relationship between urban population and NO2 pollution

Green Car Congress

A study by NASA scientists and their colleagues at Dalhousie University (Canada) and NOAA based on satellite data has found a significant correlation of surface nitrogen dioxide (NO 2 ) with population in the three countries and one continent examined: United States (r = 0.71), Europe (r = 0.67), China (r = 0.69), and India (r = 0.59).

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

Green Car Congress

As the trend toward cleaner technologies with reduced exhaust emissions continues through the use of catalytic converters, diesel particulate filters (DPF), and improved fuels and engines, non-exhaust PM will soon surpass exhaust emissions and may well become dominant by 2020 both in terms of emissions and contributions to air quality.
