Abstract
A method and corresponding system for optimizing performance of an internal combustion engine. The present invention senses gases emitted from engine combustion chambers via a first gas sensor and senses gases emitted from said engine combustion chambers subsequent to said gases passing through an engine catalytic converter via a second gas sensor. The temperatures of said first and second gas sensors are then sensed through data output from first and second gas sensors and temperature sensors. The first and second gas sensors are linearized in response to the sensed temperatures of the first and second gas sensors. The fuel level input into the engine combustion chambers is adjusted in response to linearizing of the first and second gas sensors.
