Title: Innovations of Thomas J. Large

Introduction

Thomas J. Large is an accomplished inventor based in Oxford, MI (US). He has made significant contributions to the field of vehicle technology, particularly in the area of oxygen storage capacity in exhaust systems. With a total of three patents to his name, Large continues to push the boundaries of automotive innovation.

Latest Patents

One of his latest patents focuses on the adjustment of measured oxygen storage capacity based on upstream O2 sensor performance. This vehicle system includes an upstream oxygen monitoring module that tracks an upstream exhaust oxygen sensor. It determines an upstream transition period when the sensor detects a rich-to-lean fueling transition. A delay determining module calculates a delay period associated with this detection. An upstream correcting module then establishes a corrected upstream transition period based on both the upstream transition period and the delay period. Additionally, a downstream oxygen monitoring module assesses a downstream exhaust oxygen sensor to determine its response to the fueling transition. An oxygen storage capacity (OSC) determining module calculates an OSC period based on the corrected upstream transition period and the downstream transition period. Finally, a catalyst fault detection module adjusts engine operating parameters based on the OSC period.

Another notable patent by Large involves catalyst oxygen storage capacity adjustment systems and methods. This system includes an OSC determination module that assesses the OSC period of a catalyst in an exhaust system using measurements from first and second oxygen sensors. The delay determination module identifies a delay period for the second oxygen sensor, while the correction module sets a corrected OSC period based on the difference between the OSC period and the delay period. The fault detection module indicates any faults present in the catalyst based on the corrected OSC period.
