Stationary gas engines encounter a broad range of fuels in the field. The fuels include high quality natural gases, low heating value gases from landfills, and high-propane, peak-shaving gases. These fuels have widely varying gas composition and, therefore, widely different knock tendencies, typically quantified by octane or methane number (MN). Previous work at Southwest Research Institute (SwRI) investigated gas composition effects for high quality natural gases typical of a vehicle fuel (MN 75). The current program determined the knock rating of a wide range of natural gases commonly found in stationary engine applications. The gas constituents included methane, ethane, propane, butane, pentane, hexane/heptane blend, carbon dioxide, and nitrogen. The range of MN for the present work was approximately 45 to 85. The use of this information for stationary engine applications is discussed.
