RICH BURN INTERNAL COMBUSTION ENGINE CATALYST CONTROL

摘要

The present invention relates to a catalyst system which may include a catalyst and a first sensor that detects contents of gases entering the catalyst and reports the contents of the gases entering the catalyst to an emission control module. A second sensor and a third sensor may detect contents of gases exiting the catalyst and report the contents of the gases exiting the catalyst to the emission control module. The emission control module may determine an air-fuel ratio based on the contents of gases entering the catalyst and the contents of gases exiting the catalyst. The emission control module may instruct an air-fuel regulator to operate an engine using the air-fuel ratio.
