UAIPD 14-0027: Shutoff Algorithm for Portable Gasoline Powered Generators
Shutoff Algorithm for Portable Gasoline Powered Generators
“An algorithm that can be implemented into an engine control unit (ECU) of a portable gasoline generator to improve safety and reduce emissions.
To overcome the shortfalls associated with traditional CO sensing, this algorithm does
not require CO sensors and instead uses data that is normally sensed in the control of the
fuel delivery, spark timing, and other typical aspects of engine operation to estimate the
intake of air O2 concentration. This invention inherently reduces generator emissions by tightly controlling the engine air/fuel ratio (AFR).”
