Abstract

As of January 1, 2008 idling of the main vehicle engine for the purpose of powering sleeper cabin amenities by any truck over 10,000 lbs (4,500 kg) within the borders of the state of California is prohibited unless strict emissions standards are met. In anticipation of tighter idling legislation and rising fuel prices nation-wide, idle-reduction technologies are garnering an increasing market share. These include auxiliary battery-electric power systems, primary vehicle battery systems, truck-stop electrification, diesel-fueled auxiliary power systems, and fuel-fired heaters.

The purpose of this thesis is to provide a concise, detailed compilation of currently-marketed idle-reduction technologies, propose methodologies for evaluation and comparison, develop transient energy system simulations of the most prominent idling alternatives the most suitable commercially available software, create a simple, flexible cost-comparison program, propose future developments and applications, and conduct a critical assessment from the parameters considered which technology has the greatest relative advantage.
