N2 - Biodiesel is a notable alternative to diesel fuel because it comes from natural sources, is essentially CO2 neutral, and it lowers an engine's emission of most pollutants as compared to No. 2 diesel. However, the use of biodiesel often slightly increases a diesel engine's emission of NOx. Previously proposed theories for this slight NOx increase are reviewed, including theories based biodiesel's cetane number, which leads to differing amounts of charge preheating, and theories based on the fuel's bulk modulus, which affects injection timing. A new theory explaining this NOx increase was proposed; the increase in double bonds in biodiesel, compared to No. 2 diesel, increases its flame temperature, which in turn increases NOx. NOx was predominantly due to the Zeldovich mechanism. This is an abstract of a paper presented at the 231st ACS National Meeting (Atlanta, GA 3/26-30/2006).
