With a total of three patents to her name, she has made significant advancements in diagnosing and improving the efficiency of exhaust gas aftertreatment components.
Latest Patents
One of her latest patents is titled "Method and apparatus for diagnosing exhaust gas aftertreatment component degradation." This innovative system is designed to diagnose the operation of an exhaust gas aftertreatment component for internal combustion engines. It includes a NOx sensor that produces a signal indicative of the NOx content in the exhaust gas exiting the aftertreatment component. The control circuit estimates the NOx inlet content based on various engine operating conditions and determines the NOx conversion efficiency. If this efficiency falls below a certain threshold for a predefined time, the system identifies the component as degraded.
Another significant patent is the "Control system for an engine aftertreatment system." This invention describes an engine exhaust treatment system that utilizes a control system to manage the injection of a contaminant-reducing agent into a selective reduction catalyst. The system senses the amount of contaminants in the exhaust and uses a combination of feedforward control and feedback loops to optimize the injection process, ensuring efficient operation of the catalyst.
