Abstract

A 2008 study concluded an Abrams APU could save 74 gallons of JP-8 per tank per battlefield day, which calculates to saving 4,300 gallons per brigade per day. Time at idle, estimated to be as much as 83% of total operating time. Abrams tactical idle at 1250 rpm consumes 17gal/hr. Current APU solutions consume 1.5 gal/hr. Study also showed benefit to Abrams main engine 10 year replacement costs by over $75,000 if the APU has over 500 hours mean-time between failure (due to reduced main engine idle time). Current band-aid solution does not meet requirements or power needs. Six additional batteries integrated into the available space claim allow engine off operation. Vehicle has to idle to meet 8kW power requirement (baseline turret with OIF upgrades).
