Abstract
A catalyst system may include a three-way catalyst that receives exhaust gases from an engine and an ammonia slip catalyst that receives exhaust gases from the three-way catalyst. An air injection component can be configured between the three-way catalyst and the ammonia slip catalyst. A first sensor can determine first exhaust gases data and transmits that data to a controller, while a second sensor can determine second exhaust gases data and transmit that data to a controller. The controller can estimate unmeasured exhaust gases data based on the data received from the sensors and determine a setting of a component of the system and/or of the engine based on the unmeasured exhaust gases data.
