THE DIESEL ENGINE IS NOW FULLY ESTABLISHED in a variety of applications on land and in marine use. On land, it serves to power trains, buses, trucks, and automobiles and to run construction, petroleum drilling, agricultural, and other off-road equipment. At sea, it serves both to provide main propulsion power and to run auxiliaries. Gas turbine engines also serve in a wide range of applications. Over half of the larger industrial gas turbines are in electric-generation use. Other uses include gas pipeline transmission, co-generation systems, and transportation. Cruise ships use gas turbines in newer ships to reduce vibration and stack emissions. In the military, gas turbines power a number of combatant ships both as main propulsion units and as the power source for auxiliary uses. Gas turbines are also used to power some military ground vehicles such as main battle tanks. The quality criteria and methods for testing fuels for land and marine diesel engines and for nonaviation gas turbines are sufficiently similar to address in a common chapter. Obviously, certain criteria and tests will apply to one or the other rather than both. For example, cetane number, which is a critical property for automotive diesel fuels, is of limited significance for gas turbine fuels.
