We conducted a vehicle analysis to assess the feasibility of thermoelectric technology for waste heat recovery and conversion to useful electrical power and found that eliminating the 500 W of electrical power generated by the alternator corresponded to about a 7increase in fuel economy (FE) for a small car and about 6for a full size truck. Electric power targets of 300 W were established for city and highway driving cycles for this project. We obtained critical vehicle level information for these driving cycles that enabled a highlevel design and performance analysis of radiator and exhaust gas thermoelectric subsystems for several potential vehicle platforms, and we identified the location and geometric envelopes of the radiator and exhaust gas thermoelectric subsystems. Based on this analysis, we selected the Chevrolet Suburban as the most suitable demonstration vehicle for this project. Our modeling and thermal analysis assessment of a radiator-based thermoelectric generator (TEG), however, revealed severe practical limitations.

The project focuses on various aspects of Electromagnetic Compatibility (EMC) and its significance to today's automotive signal/data communication systems that include navigation, communication, safety, information and entertainment. The requirements of various data transmission networks (interconnecting wiring and connection system) to provide interface to various systems will be discussed. The importance of EMC assurance to minimize the systems emissions and susceptibility to electromagnetic Interference (EMI) will be examined. The research focuses on the identification of critical parameters that affect the performance of the data transmission network, the development of test methodology and the analytical techniques to properly define its performance characteristics.
