Harvard/Nanjing study: China’s war on PM2.5 pollution is causing more severe ozone pollution

Green Car Congress

JANUARY 3, 2019

Paulson School of Engineering and Applied Sciences (SEAS) and the Nanjing University of Information Science & Technology (NUIST), found that while PM 2.5 pollution is falling, harmful ground-level ozone pollution is on the rise, especially in large cities. But the rapid reduction of PM 2.5 But the rapid reduction of PM 2.5

EPA launches Cleaner Trucks Initiative to update NOx standards for heavy-duty trucks

NOVEMBER 14, 2018

The US Environmental Protection Agency (EPA) has launched the Cleaner Trucks Initiative (CTI) to further decrease NO x emissions from on-highway heavy-duty trucks and engines. From 2007 to 2017, US NO x emissions dropped by more than 40%. EPA last revised NO x standards for on-highway heavy-duty trucks and engines in January 2001.

This is in contrast to the conventional mobile AC system, where the cabin air is directly cooled by the refrigerant HFC-134a, which is ozone safe but has a high GWP. The refrigerant never enters the passenger compartment and instead stays in the engine area. Only the coolant circulates through the interior air conditioning unit.

Daven Henze, an associate professor of mechanical engineering at CU Boulder, used computer modeling and NASA satellite data to simulate how particulate matter and ozone levels are, and will be, impacted by excess NOx levels in specific locations. The team then computed the impacts on health, crops and climate.

Higher octane fuels can lead to higher compression ratios which in turn can lead to more efficient gasoline engines and reduced fuel consumption. With turbocharged gasoline engines, there is a double benefit: higher compression ratios and increased boost. Earlier post.) such a fuel would result in equivalent emissions performance.

Up there, 10 to 50 kilometers above the Earth’s surface, ozone molecules absorb the sun’s ultraviolet light, protecting life far below. Even less is understood about the potential risks to people and the environment—could the particles deplete the ozone layer, for example, or significantly alter the weather?
