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

Green Car Congress

The keys to commercialization have been demonstrating cost, size and optimized energy consumption in line with automotive requirements. In particular, TPS technology offers a groundbreaking approach to reducing emissions from combustion engines and improving the environment. hp diesel engine.

San Bernardino, home to much of Southern California’s trucking and warehouse infrastructure, had 130 bad air days for ozone pollution in 2020. In the South Coast Air Basin, heavy duty vehicles such as trucks contribute 32% of mobile source nitrogen oxide emissions that react in the atmosphere to form ozone and particulate matter.

MIT study: half of US deaths related to air pollution are linked to out-of-state emissions

Green Car Congress

To make further progress, we should start focusing on road transportation and commercial and residential emissions. The research was a collaboration between MIT’s Laboratory for Aviation and the Environment and the MIT Joint Program on the Science and Policy of Global Change. and/or ozone.

The decrease in CO 2 equivalent emissions of ODSs (ozone-depleting substances: CFCs, halons, HCFCs, and others) may be offset by the projected increase in their non-ozone depleting substitutes (HFCs) (lines designated as HFC scenarios). Climate and the Ozone Layer. Source: UNEP. Click to enlarge.

Study finds significant slowdown in decrease of NOx emissions in US; implications for air quality management

Green Car Congress

They found that levels of pollutants that can contribute to the formation of ground-level ozone, or smog, have failed to continue a fairly steady decline as estimated by the US Environmental Protection Agency. These results show that meeting future air quality standards for ozone pollution will be more challenging than previously thought.

New international study finds lab testing of diesel NOx emissions underestimates real-world levels by up to 50%

Green Car Congress

in collaboration with scientists at the University of York’s Stockholm Environment Institute (SEI); University of Colorado; and the International Institute for Applied Systems Analysis, assessed 30 studies of vehicle emissions under real-world driving conditions in 11 major vehicle markets representing 80% of new diesel vehicle sales in 2015.
