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.

Study shows significant reductions in real-world heavy-duty diesel emissions from 2010 regulations

Green Car Congress

New research from North Carolina State University found that federal requirements governing diesel engines of MY 2010 tractor trailer trucks have resulted in major cuts in real world emissions of particulate matter (PM) and nitrogen oxides (NO x ). A 2010 truck emitted 2 grams of NO x per gallon of fuel—a decrease of 98%.

Study finds high exhaust temperatures within NTE operation for heavy-duty diesels with aftertreatment systems contribute to high nanoparticle concentrations

Green Car Congress

The transient results illustrate the gradual formation of the nucleation mode particles with continuous increase in exhaust temperatures. Current 2010 USEPA emissions standards for NO x and PM are set at 0.20 The team used a MY 2007 Volvo MD11 engine compliant with USEPA 2007 emissions standards. Click to enlarge.

MECA report assesses technology feasibility for heavy-duty diesel trucks to meet lower NOx standards by 2024

Green Car Congress

The Manufacturers of Emission Controls Association (MECA) released a report assessing market-ready technologies being commercialized by suppliers of emission control and efficiency components for heavy-duty diesel vehicles to meet lower intermediate standards for oxides of nitrogen (NO x ) by 2024 as a transition to final standards in 2027.

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.
