Comparative study finds that B20 increases emission rates of a number of pollutants in both light- and medium-duty diesel engines at idle

Green Car Congress

They found that the level of emissions of regulated and unregulated pollutants in diesel exhaust depends on fuel, load, engine calibration, and exhaust aftertreatment technology.

New mixed-oxide catalysts shown as viable substitute for platinum catalysts for diesel exhaust aftertreatment

Green Car Congress

Under laboratory-simulated diesel exhaust conditions, this mixed-phase oxide material was superior to Pt in terms of cost, thermal durability, and catalytic activity for NO oxidation. Nanostellar was founded in California in 2004 by scientists from Stanford University and NASA Ames Research Center. Kyeongjae Cho.

CRC ACES Phase 2 report finds emissions from modern heavy-duty diesels well below required levels

Green Car Congress

2010 engines emissions reduction relative to 2010, 2007, and 2004 US emission standards. For a number of the most important pollutants, levels were substantially lower than required by regulations. These reductions came while emissions of fine particles were also 92% lower than the 2010 standard 99% lower than 2004 emissions.

European Commission fines truck producers record €2.93B for colluding to pass on emission compliance costs

Green Car Congress

Between 1997 and 2004, meetings were held at senior manager level, sometimes at the margins of trade fairs or other events. From 2004 onwards, the cartel was organized via the truck producers’ German subsidiaries, with participants generally exchanging information electronically. This was complemented by phone conversations.
