Abstract:

A natural gas-fueled Auxiliary Power Unit APU was developed for use in a hybrid electric vehicle. The project involved conversion and development of the powerplant from gasoline to natural gas operation, application of an engine control system, application of a three-way catalyst system, development of an APU controller, and integration and testing of the APU in the laboratory and vehicle environment The project was divided into three phases 1 engine development, 2 APU control system development, and 3 APU integrationtesting. The resultant APU was integrated into a hybrid electric utility truck for use as a range extender in a series hybrid configuration. The project resulted in an APU configuration producing ultra-low emissions levels while achieving high efficiency due to implementation of a unique APU operating strategy.
