Latest Patents

Yong Xu's latest patents include the "Asymmetrical Oxygen Sensor Diagnostic and Degradation Compensation Systems." This diagnostic system for an engine features an oxygen detection module, a timing module, and a control module. The oxygen detection module receives an oxygen signal from an oxygen sensor that detects the oxygen level in the engine's exhaust system. The oxygen signal has N rich states and M lean states, where N and M are integers greater than or equal to 1. The timing module determines a rich period when the oxygen signal is in at least one of the N rich states and a lean period when the oxygen signal is in at least one of the M lean states. The control module detects an asymmetrical error with the oxygen sensor based on a comparison between the rich period and the lean period. Another significant patent is the "Method of Crank Signal Disturbance Compensation." This engine system compensates for disturbances in a crankshaft signal. It includes an error module that computes an error between an ideal period and an actual period of a crankshaft signal, a correction factor module that determines a correction factor based on the error, and a compensation module that applies the correction factor to the actual period of the crankshaft signal.
