| Diesel particulate emissions have been recognized as carcinogenic by various agencies, including the EPA, NIOSH (National Institute of Occupational Safety and Health), etc. and diesel emission is a significant source in Cincinnati. In this study, the diesel emissions from the use of a biodiesel blend were measured and compared against that of petro-diesel. Diesel particulate matter (DPM), the carbon speciation of DPM, CO and NOx were measured. The measurements were performed on a non-road source and various loads from idle to full speed have been tested. The DPM from B20 is 10-15% lower than that of petro-diesel. The emissions of CO and NOx were close for the two fuels. This is consistent with an existing study and it indicated that the effectiveness of biodiesel in pollutant emission reduction may be more obvious with more biodiesel usage. |
