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.)

Reduction in diesel carbonyl emissions using F-T fuel from coal

Green Car Congress

Other research has shown that carbonyls directly influence physiological response to diesel exhaust particles and can also contribute to secondary organic aerosol formation. Jakober, 2008).

Eaton contributing several components to DOE SuperTruck II program

Green Car Congress

Since 2008, Eaton’s Vehicle Group has been laser-focused on reducing emissions and fuel consumption. We have—and continue to develop—technologies that reduce NO x emissions and improve the overall fuel economy of internal combustion diesel engines, as well technologies for electric, hybrid and fuel cell commercial vehicles.

Mazdas new SKYACTIV gasoline and diesel engines are steps on the road to its Ideal Engine; focus on compression ratio

Green Car Congress

However, while Mazda plans to offer hybrid vehicles in the medium-term, its engineers are pushing hard to increase the efficiencies of both the gasoline and diesel platforms, moving toward what they call “the ideal Internal Combustion Engine.” This corresponds to a 23% reduction in fuel consumption and, therefore, CO 2 output.).
