Engine Lubricant compact and cheaper to manu- facture than current auto engine types and will feature cleaner exhaust emissions. Prototype engines have been extensively tested and MUDCO hopes to effect a licensing arrangement with a manufacturer in the near future. NASA technology is incorpo- rated in the Rotorcam engine in the form of a valve coating. MUDCO chief engineer Richey was aware of Lewis Research Center's development of a fami- ly of materials thaf provide engine lubrication over a wide NASA COATING temperature range. MUDCO selected the plasma-sprayed PS 212 as a coating for the TECHNOLOGY IS I Rotorcam's valves to eliminate the need for a liquid lubricant. INCORPORATED IN PS 212 contains 70 percent chromium carbide, 15 percent silver and 15 percent barium A NOVEL fluoride/calcium fluoride; the carbide acts as a wear resistant AUTOMOTIVE ENGINE matrix and the silver and fluo- - I rides serve as low and high temperature lubricants, respec- Mu rray United Developmer The Rotorcam has no crank- tively.
