High Temperature Tribological Lubricants for Low Heat Rejection, High Temperature Operation Diesel Engine

Surfaces Research proposes optimization and engine endurance demonstration of an innovative tribology system for Future Combat System (FCS) diesel engines. Our new extreme-temperature engine lubricant and self-lubricating cylinder liner coatings will be evaluated in NATO-cycle endurance testing. In the Phase I program, we developed the extreme-temperature engine lubricant using Surfaces Research proprietary basestocks and additives. We successfully demonstrated our high-temperature multicylinder test engine at FCS conditions. We tested our new lubricant at these conditions. Our test data predict the lubricant will function for over 200 hours at maximum engine torque and temperature. In the Phase I Option, we will evaluate our lubricant with our optimized self-lubricating cylinder liner coatings. In Phase II, we will demonstrate the lubricant and coatings in a high-temperature 400-hr NATO-cycle engine endurance test, the most rigorous U. S. Army qualification procedure. Our program of lubrication and coating optimization will driven by performance benchmarks from our high-temperature multicylinder engine tests. We will conduct life-cycle cost/benefit analyses in close coordination with FCS engine developers, to meet FCS and future Army goals. The success of the FCS diesel engine depends on the extraordinary high-temperature performance of Surfaces Research lubricants.
