This paper describes the objectives and experimental design of a program to study the characteristics of propane as a low emission fuel. Results of preliminary work are given to show how emissions (using propane) vary with ignition timing, air-fuel ratio, speed, and load. Comparable data relating air-fuel ratio and emissions are shown for gasoline and natural gas. The bulk of these data are from experiments with a single-cylinder engine and from one-full-scale engine; tests with both were run using an engine dynamometer operated at steady-state modes only. However, the principal study will involve full-scale engines and vehicles as they typically are used, and this progress report includes results of one series of tests to show the influence of ignition-timing schedule on exhaust emissions from a light sedan fueled with propane and operated through simulated traffic cycles.
