Single Cylinder Engine Evaluations of Stabilized Diesel Fuels Containing Alcohols
Stabilized fuels containing methanol or ethanol, contamination water, and cherrical stabilizer were evaluated in an ASTM c-etane rating engine and commercial Direct (DI) and Indirect (IDI) injection engines. Engine speed and load conditions were selected to provide adequate smoke and particulate emissions for accurate measurements. All fuels were tested at equal energy input rates for the given engine. The cetane engine results were quite variable compared to those from the other engines. For operation with the stabilized fuels: All three engines demonstrated only minor changes in HC, CO, and NOx emissions and engine efficiency. The cetane engine demonstrated very little change in the smoke and particulate emissions; the DI engine showed substantial reduction in smoke and particulates; and the IDI engine showed a consistent but smaller reduction in smoke and particulates. The Soluble Organic Fraction of the particulate emissions increased significantly for the stabilized fuels operating in the DI engine. This increase was not as pronounced for the IDI engine. Fuel related operational problems are also described. © Copyright 1983 Society of Automotive Engineers, Inc.
