Compare virgin soybean oil to recycled waste cooking oil biodiesel fuel blends for (1) light-duty diesel engine combustion particle primary and secondary composition; and (2) role of fuel additives on particle chemistry.
Collect engine emissions test filters for different blends of neat soybean and waste cooking oil biodiesel fuels prepared under identical processing conditions. 1. Quantify organic composition of exhaust particulate matter using thermal desorption- gas chromatography/mass spectrometry and high-resolution liquid chromatography/mass spectrometry. 2. Quantify inorganic composition of exhaust primary particulate matter using ICP-MS. 3. Quantify changes in organic composition of PM after exposure to 4 ppm ozone for 24 hours. 4. Relate antioxidant fuel additive composition to biofuel stability, PM composition and reactivity. Data will be analyzed to develop differential models for biodiesel combustion products on the basis of feedstock origin and fuel pre-processing.
