Overview of industrial gas engines and their lubrication. Part 1. A. Zareh. Lubric Engng., October 1996, 52(10), 730--740.
A comprehensive review of gas engines is presented. Typical properties of natural gas fuels from different sources are tabulated and other gaseous fuels such as LPG, biogas, landfill gas, and products produced by bacterial decomposition of solid wastes are also discussed. Some important properties of gaseous fuels are described. Spark-ignition, dual fuel, and diesel type gas engines are reviewed and five main differences between gas engines and diesel/petrol engines are discussed. Applications for gas engines are reviewed and advantages and disadvantages are described. Other topics discussed are gas engine emissions, three-way catalysts, selective catalytic reduction, and oxidation catalysts. 14 refs.
