ABSTRACT:
The composition of an exhaust gas stream from an internal combustion engine is analyzed using an infrared sensor detecting infrared radiation from a catalyst passing the exhaust gas. The infrared sensor provides signals indicating the presence of certain gases. These signals can be used to generate an engine control strategy to adjust the composition of the exhaust gas.
