Abstract : Limited evaluations were conducted on the M998 High Mobility Multipurpose Wheeled Vehicle (HMMWV) and the M977 Heavy Expanded Mobility Tactical Truck (HEMTT). The data that these evaluations would yield included startability and idle quality, acceleration rates, and fuel consumption. The previously tested M88Al Medium Recovery Vehicle was also evaluated. However, these evaluations would determine if a Teledyne Continental Motors-recommended fuel injection and metering pump adjustment would increase performance and allow the engine to achieve its rated horsepower. As a result of these evaluations, it was determined that the conversion to JP-8 from DF-2 increased the acceleration time of both the M998 and M977 vehicles. Also, the fuel consumption increased on both vehicles; however, the increases were below that predicted by the heating value difference between the two fuels. The M88Al exhibited an increase in power while pulling its own weight after the pump adjustment; however, the power increase was not noticeable while towing the M1A1 tank....
