Evaluation of High-Temperature Diesel Engine Liquid Lubricants 952544

High-temperature lubricant (HTL) requirements for future U.S. Army ground vehicles were investigated. A single-cylinder diesel engine (SCE-903) was successfully modified to operate at increased cylinder liner temperatures and to serve as a tool for HTL evaluation. Oil D, one of six lubricants evaluated, completed 200 test hours at an average cylinder wall temperature of 247°C and an oil sump temperature of 166°C with only minor oil degradation. However, improved piston cleanliness is desired.
