New high-temperature lubricants are being developed for future U.S. Army low heat rejection diesel engines. Compared to the best previous low heat rejection diesel engine lubricant, the first new lubricant developed was shown to (1) be less volatile, (2) have 55 Cel (100 deg F) greater oxidative stability, and (3) increase high-temperature single cylinder engine life more than five times. The new lubricant successfully completed a 400 hr multicylinder engine test in the U.S. Army 5-ton truck adiabatic engine. Lubricant property changes, engine wear, deposits and oil consumption were all very low. Two additional new liquid lubricants were developed for operation at higher engine temperatures than those of the 5-ton truck. Engine tests of these new lubricants will be conducted in the near future. Hybrid liquid/solid lubricants were formulated and evaluated for potential reduction of wear and friction at high temperature, with mixed results.
