One of the U.S. Army’s key goals is greater energy efficiency. Saving fuel not only saves money, but can also save lives by reducing the frequency of supply convoys in dangerous territory. The Army has a number of initiatives under way to reduce energy consumption and to produce 25% of the energy it uses from renewable sources. Cummins Power Generation and Cummins Inc. exhibited products to support these efforts at the recent conference of the Association of the United States Army (AUSA) in Washington, D.C.
Cummins Inc. is the largest supplier of diesel engines for defense purposes in the Western world, with some 250,000 engines in military and naval service. Its latest models feature high power-to-weight ratios and excellent fuel efficiency.
Cummins Power Generation was one of three companies originally selected to build prototypes of a new mobile generator line, then was the single contractor selected to build pre-production units and later was chosen to commence full-rate production of the Advanced Medium Mobile Power Systems, or AMMPS.
The new AMMPS generators, available from 5–60 kW, are 10% smaller than the previous TQG line of generators and 21% more fuel-efficient. Compared with the older generators, AMMPS units are projected to save $35 million and 2.4 million gallons of fuel per year. Another advantage of the new AMMPS models is their ruggedness. Able to be dropped by parachute if needed, these units are 50% more reliable than their predecessors. The AMMPS units are proving their value already, with some 1,600 being fielded to Afghanistan.
