This paper describes a newly-developed, high-performance RTD,(Resistive Temperature detector), which meets OBD-II monitoring requirements. The OBD-II catalyst monitoring requirements are high temperature durability, high accuracy, and narrow piece-to-piece variation.
Catalyst monitoring methods have been reviewed and studied by checking the catalyst exotherm(1)(2).
The preliminary test results of catalyst monitoring are also described herein.
