Reduced Engine Idle Load (REIL) System for Conventional Propulsion Diesel & CNG Buses: Development, Validation & Market Study Program Final Report (Report 0157)


The Center for Transportation and the Environment partnered with New Flyer, BAE Systems and MARTA to design, build, test and evaluate the technology and market readiness of a Reduced Engine Idle Load (REIL) system for diesel and CNG (compressed natural gas) transit buses. A REIL system replaces traditional mechanically-driven accessories with electric accessories to increase fuel efficiency, reduce emissions, and simplify maintenance on conventional propulsion transit bus fleets. This project received funding under FTA’s Bus Efficiency Enhancements Research and Demonstration (BEERD) Program.
