Diesel-powered compression ignited engines contribute large amounts of sub-micron particulate matter to the environment and have been shown to contribute to atmospheric greenhouse gases and deleterious health effects. Biodiesel is a proposed alternative biofuel produced through transesterification, a process in which organically derived oils combine with a methyl or ethyl alcohol in the presence of a catalyst, typically potassium or sodium hydroxide, to form ethyl or methyl ester. This biomass derived ethyl or methyl ester is non-toxic, less odorous, biodegradable, renewable, and safer to handle than petroleum diesel. Biodiesel can mix with conventional petroleum diesel fuel or used as a neat fuel in compression ignited engines. The main objectives of the research are to compare selected emissions of petroleum diesel fuel with biodiesel fuel and fuel blends, soybean as the source oil, under different engine conditions in order to determine its impact on air quality. A non-road diesel engine generator allowed for the characterization of the emissions from operating on petroleum diesel fuel, B50, and B100. The particulate matter and gaseous emissions were collected with a high-volume single dilution sampler and the exhaust stream was evaluated with a gas analyzer. The filters utilized for particulate matter collection and the adsorbents employed for gaseous pollutant collection were extracted for organic analysis with GC/MS instrument. The organic composition of the fuels and the emitted particulate matter and gaseous pollutantswere compared at various engine loads. The use of biodiesel in compression ignition engines has shown to be a viable alternative to petroleum diesel. Biodiesel is an environmentally sustainable fuel that does not contain sulfur or aromatics and may decrease the overall detrimental effects of diesel-powered engines.
