TACOM/CUMMINS ADIABATIC ENGINE PROGRAM

摘要: This paper discusses the goals, progress, and future plans of TACOM/Cummins Adiabatic Engine Program. The concept insulates diesel combustion chamber with high temperature materials to allow hot operation near an adiabatic condition. Additional power improved efficiency derived from this occur because thermal energy, normally lost cooling exhaust systems, is converted useful through use turbomachinery high-temperature materials. testing has repeatedly demonstrated be most fuel efficient engine in world multi-cylinder performance levels 0.285 LB/BHP-HR (48% efficiency) at 450 HP representative. Installation early version within a military 5 ton truck been completed, initial vehicle evaluation successfully accomplished. Design procurement long lead time items for next generation 600-750 range continuing. Work on minimum-friction continues.
