Abstract:
An exhaust aftertreatment system includes a pump configured to circulate a reagent, an injector configured to deliver the reagent into an exhaust stream, a sensor configured to (i) measure an operating parameter of the aftertreatment system and (ii) output a signal that indicates a value of the measured operating parameter, and a control module configured to control the injector based on the signal outputted by the sensor. The control module includes a correction coefficient determination module configured to generate a correction coefficient based on the signal outputted by the sensor. The control module further includes an injector control module configured to receive an injector flow control signal, determine a pulse width modulation (PWM) signal based on at least the injector flow control signal, and generate an injector control signal that controls actuation of the injector based on at least the correction coefficient and the PWM signal.

Claim (Index 1):
An exhaust aftertreatment system comprising:\n a pump configured to circulate a reagent; an injector configured to deliver the reagent into an exhaust stream; at least one sensor configured to (i) measure an operating parameter of the aftertreatment system and (ii) output a signal that indicates a value of the measured operating parameter; and a control module configured to control the injector based on the signal outputted by the at least one sensor, wherein the control module includes:\n a correction coefficient determination module configured to generate a correction coefficient based at least on the signal outputted by the at least one sensor, and \n an injector control module configured to:\n receive an injector flow control signal that indicates a target flow rate of the reagent, \n determine a pulse width modulation (PWM) signal based on at least the injector flow control signal, and \n generate an injector control signal that controls actuation of the injector based on at least the correction coefficient and the PWM signal.
