US study of miners links heavy exposure to diesel exhaust to increased risk of lung cancer death; researchers suggest implications for urban areas with high exhaust concentrations

Green Car Congress

In a study of non-metal miners in the US, federal government scientists report that heavy exposure to diesel exhaust increased risk of death from lung cancer. For never-smokers, risk of lung cancer death increased with increasing diesel exhaust exposure. effect of diesel exhaust exposure on lung cancer mortality in.

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. Earlier post.) Earlier post.)

Audi testing find e-ethanol and e-diesel produced by Joule often perform better than conventional counterparts

Green Car Congress

Our test shows that as well as electric driving on renewable electricity, there are other concepts that permit long-distance, low-emission driving. During each of up to 3,000 revolutions per minute in the research engine, a minute amount of fuel shoots into the glass cylinder, is compressed and ignited, and the exhaust gas then expelled.

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.

New exhaust catalyst features thermal durability and high reactivity at low operating temperatures

Green Car Congress

Catalytic converters have been used in the US since the 1970s as a way to clean up pollutants from vehicle exhaust. As cars have become more fuel-efficient, however, they use less energy and the temperature of the exhaust gases is lower, which makes it harder to clean up the pollutants. —Yong Wang.

Texas Clean Energy Project signs long-term CO2 offtake agreement with Whiting Petroleum for enhanced oil recovery; 90% CO2 capture from IGCC coal polygen plant

Green Car Congress

Its high carbon-capture rate reduces the total amount of CO 2 emitted to the atmosphere to less than 10% of the emissions for power from a conventional coal plant, and less than 25% of those for power from a highly efficient, natural gas-fired plant, according to Summit.
