Abstract Details

2014, Master of Science, Ohio State University, Mechanical Engineering.
A flexible model-based vehicle platform was developed with all the appropriate aftertreatment components and sensors for a GDI engine having the ability to perform diagnostic analysis. This model was developed by integrating aftertreatment and sensor models available in the public domain to develop a platform capable of running different drive cycles and scaling across different vehicle platforms with minor changes. Faults were identified for each system and the model was added with the capability to inject those faults to analyze the ability of the sensor set to diagnose those faults. Results have been presented representing the working of the model when the faults are injected. A Design of Experiments (DOE) study was conducted to explore the design space of the GPF and understand the impact of the design parameters on the performance of the filter. It was concluded from the study that smaller filters can be used due to low soot loading and soot can be regenerated passively without any need for external heating. It was observed that ash loading in the filter may be a critical issue during the long run.
