Latest Patents

Ovist's patent, titled "Adjustment of measured oxygen storage capacity based on upstream O2 sensor performance," introduces a sophisticated vehicle system. This system includes an upstream oxygen monitoring module that tracks the performance of an upstream exhaust oxygen sensor. It determines an upstream transition period when the sensor detects a rich-to-lean fueling transition. Additionally, a delay determining module calculates a delay period related to the sensor's detection of this transition. The system also features an upstream correcting module that adjusts the upstream transition period based on the delay period. Furthermore, a downstream oxygen monitoring module assesses a downstream exhaust oxygen sensor's response to the fueling transition, while an oxygen storage capacity (OSC) determining module calculates the OSC period based on both upstream and downstream transition periods. Lastly, a catalyst fault detection module adjusts engine operating parameters based on the OSC period.
