New nanostructured earth abundant metal catalysts rival platinum on a weight basis; diesel emissions treatment

Green Car Congress

A development in catalysis research by academics at the Universities of St Andrews and Newcastle could lead to new systems to treat diesel emissions. Catalysts are typically metallic nanoparticles—often platinum group metals—that are finely deposited upon a substrate. Irvine & Ian S.

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.)

UNECE: claim that diesel on-road vehicles are the cause of increased lung cancer is misleading

Green Car Congress

A discussion paper published by the United Nations Economic Commission for Europe (UNECE) asserts “ with a high degree of reliability that it is misleading to claim that people’s exposure to diesel engines of road motor vehicles is the cause of increased risk of lung cancer. ”. —“Diesel Engines Exhausts: Myths and Realities”.

Study finds that diesel school bus emission retrofits reduce tailpipe emissions, but dont do much for pollution in passenger cabin

Green Car Congress

A UCLA study of the performance of retrofit systems for diesel-powered school buses has found that while the systems significantly lowered tailpipe emissions, there was no unequivocal decrease for in-cabin air pollutants after retrofitting.

Intangles Lab launches Diesel Particulate Filter (DPF) technology – ET Auto

Baua Electric

has unveiled its Diesel Particulate Filter ( DPF ) solution. Amidst growing environmental concerns and stringent emissions regulations, diesel engines have encountered the formidable challenge of soot accumulation in DPFs, resulting in clogs that degrade engine performance and increase maintenance costs.

Researchers propose low-temperature SOFC unit for reducing NOx and oxidizing HCs in lean-burn engine exhaust

Green Car Congress

Concept of the SOFC emissions control system. A team from National Tsing Hua University, Taiwan, reports that a low-temperature solid oxide fuel cell (SOFC) emissions control system for lean-burn engines can simultaneously reduce the high concentrations of NO x and oxidize hydrocarbon (HC) emissions.

International automotive researchers emphasize the importance of continued development of the internal combustion engine

Green Car Congress

The article provides an assessment of the state of power generation in the world today, and provides analyses of productive directions for the future. It is very likely that highly efficient “fully flexible” engines with hybridized solutions will be a big part of sought-after efficiency improvements, as well as emission/GHG reductions.
