Surfaces Research proposes development of an innovative new extreme-temperature engine lubricant. We propose a high-temperature multicylinder engine test of the lubricant in a Surfaces Research engine operating at Future Combat System (FCS) conditions. The new lubricant has exceedingly long useful life at high temperature, outstanding resistance to high-temperature deposit formation, and unparalleled wear and friction performance. We will also demonstrate an innovative, self-lubricating cylinder liner coating that will further enhance engine performance. Surfaces Research has developed engine oil and tribological system technologies specifically to meet the high-temperature longevity and performance requirements of the FCS engine. We propose a program of high-temperature lubricant development and tribological system selection driven by performance results in Surfaces Research's FCS-condition engine, in collaboration with TARDEC's North American FCS engine team. The success of the FCS diesel engine depends on the extraordinary high-temperature performance of Surfaces Research lubricants. Surfaces Research new lubricants are the enabling technology for the Future Combat System engine. The new high-temperature lubricants for FCS and other advanced diesel engines will impart large increases in fuel efficiency, power density, and durability, and will lower maintenance costs both for equipment overhaul and by allowing extended lubricant drain intervals. Military, commercial, and recreational applications will benefit from the selection of multigrade and single-weight oils with excellent on-road performance. Excellent long life and heat tranfer properties support efforts for "single-fluid-sealed-for-life" systems. Commercialization currently underway is based on demonstrated excellent performance in NASCAR and commercial diesel engines.
