Exhaust gas temperature sensor for OBD-II catalyst monitoring

摘要

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 temperate durability, high accuracy, and narrow piece-to-piece variation. Catalyst monitoring methods have been reviewed and studied by checking the catalyst exotherm. The preliminary test results of catalyst monitoring are also described herein.
