Army Ground Vehicle Propulsion.

摘要

Army Ground Vehicle requirements/expectations: Demanding ambient conditions ranging from Artic-like to Desert-like; Must operate on compression ignition fuels global jet and diesel fuels; Must have minimal maintenance schedules -Must protect the occupants; Need to tow other vehicles, climb steep grades, corner at medium to high speeds, carry around cargo, pull themselves out of ditch while sitting on one track, pivot steer, operate in soft soil, and Increasing need for more on-board electrical power. The Army can not buy 2007 or Tier IV (> 75 bhp) compliant COTS engines and directly integrate into current and new heavy-duty vehicles. Declining availability of COTS engines for Army trucks as suppliers include various engine emissions technologies on engines that negatively impact Army vehicle performance/reliab ility/durability.
