A formal ongoing program to characterize the performance and exhaust characteristics of automotive-type powerplants fueled by conventional and alternative fuels is reported. This report contains the information obtained during the past three years when four alternative fuels and two baseline fuels were evaluated in three engines. The four alternative fuels were a simulated gasoline made to represent coal derived gasoline, methyl aryl ethers blended at the 10% level in an unleaded gasoline, gasoline made from methanol, and a blend of Indolene plus methanol and higher alcohols. The two baseline fuels were, Indolene and Gulf unleaded regular gasoline. The engines tested were a pre-mixed carbureted SI (spark ignition) engine, a carbureted three-valve stratified-charge SI engine and a pre-mixed carbureted SI engine with a closed-loop three-way catalyst emission control system.
