Abstract
This study is to use refinery bases as parameters and not conventional physical or chemical parameters. For each engine, tests have been run on a steady state bench with variations of some tuning parameters. PM (Particulate Matter), SOF (Soluble Organic Fraction), Sulfate and PAHs (Polycyclic Aromatic Hydrocarbons) were measured for a 11 liter heavy-duty diesel engine with two different diesel fuels. Sulfate was extracted by sonication of PM trapped filter and analyzed by ion chromatography. PAHs in SOF were analyzed by high performance liquid chromatography. PM (g/kWh) emission was high at lower engine load. The fuel density affected the PM and SOF emission characteristics. The fuels with high density resulted in high PM and SOF emission. SOF increased as engine load decreased at low speed. SOF was around 50% in high speed range at all tested engine load conditions. Maximum ratio of sulfate was about 2% of total PM mass at rated power and PAHs was 0.1~0.6 % of total PM mass.
