The general objective of the Automotive Technology Status and Projections task of the Jet Propulsion Laboratory is a continuing assessment of automotive technology. It considers both current and advanced conventional engines, advanced alternative engines, advanced power train components, and other energy-conserving vehicle modifications which could be implemented by the year 2000. Vehicle-level projections of fuel economy and emission potentials of these power systems are secondary objectives. A major thrust is determination of potentials of Brayton and Stirling heat engine power systems when compared with evolving conventional systems such as diesel or uniform-charge or stratified-charge Otto engines. Factors considered include fuel economy, emissions, multifuel capability, use of advanced materials, and cost/manufacturability. Each candidate system is evaluated for its ability to meet not only current legislated emissions standards, but also those possible in the future, e.g., 0.4 g/mi NOx.
