Latest Patents

Clemens' latest patents include a system and method for performing evaporative leak diagnostics in a vehicle. This innovative method involves commanding a valve in a diagnostic module to a vent position, connecting the fuel system to the atmosphere. A pump in the diagnostic module is operated to measure a reference pressure across an orifice, providing a threshold for diagnostics. The valve is then commanded to a test position, and the pump is operated to place the fuel system in a low-pressure state. A series of pressures in the fuel system is measured, and a diagnostic code is generated by comparing these pressures to the established threshold. This process enhances the accuracy and efficiency of leak diagnostics in vehicles.
