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. L/2004 calibration engines. L/2004 calibration engines. L) and medium-duty (6.4 Their paper appears in the ACS journal Energy & Fuels.

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.

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.

Diesel exhaust contains a variety of harmful gases and more than 40 other known cancer-causing substances. Both pollutants are particularly harmful to children, the elderly and those who have preexisting health problems. BNSF has been operating four liquefied natural gas yard locomotives in downtown Los Angeles since the mid-1990s.
