Title: Ann Irene Sipes: Innovator in Automotive Diagnostics
Introduction
Ann Irene Sipes is a notable inventor based in Milan, MI (US). She has made significant contributions to the field of automotive diagnostics, holding a total of 3 patents. Her work focuses on improving vehicle systems, particularly in the area of evaporative leak diagnostics and vapor purge systems.
Latest Patents
One of her latest patents is titled "System and method for performing evaporative leak diagnostics in a vehicle." This method involves a diagnostic module that commands a valve to a vent position, connecting the fuel system to the atmosphere. A pump is operated to measure a reference pressure across an orifice, providing a threshold for diagnostics. The valve is then commanded to a test position, placing the fuel system in a low-pressure state, where a series of pressures are measured to provide a diagnostic code after comparison to the threshold.
Another significant patent is "Vapor purge system integrity diagnosis for a hybrid vehicle." This method tests a vapor purge system (VPS) for an internal combustion engine and a hybrid vehicle. It includes a controller that closes a first valve between a carbon canister and the ambient environment, while the engine is motored to pull a vacuum on the VPS. The pressure in the VPS is monitored to ensure its integrity.
