摘要:
A system for determining a reagent solution quality indicator includes a reagent solution source for supplying the reagent solution to an emissions catalyst configured to receive a NOx-containing gas therethrough, means for determining a flow rate of NOx reduced from the gas by the catalyst, means for determining a flow rate of the reagent solution into the catalyst, and a control circuit determining the reagent solution quality indicator as a function of the NOx flow rate and the reagent solution flow rate. The system may additionally be configured to diagnose reagent solution quality by configuring the control circuit to monitor the reagent solution quality indicator over time and produce a fault value if the reagent solution quality indicator crosses a reagent quality indicator threshold, and to diagnose the catalyst by producing another fault value if the catalyst capacity point falls outside of a catalyst capacity point threshold.

Through the use transfer functions, or other modeling types, directed toward the individual operation of an engine and after-treatment subsystems, an optimizer determines the trade-offs between fuel consumption, urea consumption, and reduction of NOx and PM emissions for each component of the integrated system. Evaluation of these trade-offs permits the optimizer to dictate how each component should be controlled, or adjusted, to achieve optimal fuel (and urea) consumption while meeting the constraints bounding the solution. Response characteristics can be triggered by adjusting certain engine operating levers in order to achieve optimal performance of the integrated system.

摘要:
A method and system for improving sensor accuracy of diesel emissions is disclosed. The method and system comprises changing the sensor reading as a function of sensor age to provide a more accurate measure of the diesel emissions. By estimating the degree of sensor error and then providing a gain correction factor as a function of sensor age, a more accurate measure of the diesel emissions is provided.

A flue protector system and methods of manufacture can include: forming an attachment plate including a tab configured to fix the attachment plate to an upright column without the use of a tool; and forming a bumper extended from the attachment plate, the bumper defines a flue space extending to the upright column.
摘要:
A system for measuring NOx content of an exhaust gas produced includes at least one controllable valve operable to direct exhaust gas to a NOx sensor only when measurement of the NOx content is desired and to otherwise expose the NOx sensor to ambient air. A control circuit controls the operation of the at least one valve and determines the NOx content of the exhaust gas based on sensory data received from the NOx sensor.
