Today’s automobiles lack flexibility in design and contribute to the major portion of pollution. This project intends to design, develop, evaluate, and demonstrate the feasibility of smart sensors for utilization in advanced transportation to reduce pollution. The project objectives are: (1) Design and performance test oxygen sensors for combustion engines and (2) Demonstrate the temperature independent “smart sensing” features for emission control and fuel efficiency in transportation systems. This is the Phase-II of a multi-year project. The methodologies to be developed are expected to be applicable in a broader context.
