Catalytic converter function detection |
摘要 |
A method and system detects the function of a catalytic converter in a vehicle using data received from an open path emissions sensor. The factors considered include whether the vehicle moving on a road is operating in a closed loop operating condition, whether the vehicle is operating in a cold start mode, and the hydrocarbon and other tailpipe emissions concentrations in an exhaust stream of the vehicle as measured by the open path sensor.
