Abstract
A fuel control system for controlling the purging of alternate fuel in an internal combustion engine at shutdown includes: at least one valve device configured to deliver a fuel supply to the engine; a first fuel source configured to provide a primary fuel to the valve device; a second fuel source configured to provide an alternate fuel to the valve device; and a controller connected to the valve device and adapted to be connected to an ignition system. The controller is configured to control the valve device responsive to a status of one of the engine and the ignition system.
