ABSTRACT:
This specification discloses a step function lean burn sensor for determining the partial pressure of oxygen in an exhaust gas. Such a measurement is useful for air fuel ratio control in an internal combustion engine. This device uses the electrical properties of an electrochemical pump cell to determine the step function output. The device utilizes the qualitative nature of the current-voltage characteristic of the pump cell to reduce requirements on cell fabrication.
