Abstract:

A high-output two-cycle diesel engine model 6V53T was subjected to a targeted 240-hour laboratory-dynamometer endurance test cycle using two different MIL-L-2104C SAE grade 30 engine lubricants. Results show these lubricants are compatible with the engine when operating with reference no. 2 diesel fuel 0.44 percent natural sulfur. Also, the 240-hour tracked-vehicle test cycle was found to be more severe for engine and lubricant when compared with previously obtained data for this same engine and fuel operating under the 210-hour wheeled-vehicle test cycle. A third MIL-L-2104C lubricant was evaluated in the 210-hour wheeled-vehicle test cycle and it was found to produce acceptable performance, ranking between the two previously tested lubricants. Recommendations for additional testing are made.
