Abstract
A fuel feed device for an internal combustion engine including a main fuel system including a charge forming device that supplies fuel, air requirements to the engine for most running conditions. An automatically operated auxiliary supply system is provided for supplying additional fuel and, in some instances, air to the engine in response to specific running conditions such as cold starting or cold enrichment. This system includes an automatically operated valve for controlling the fuel discharge. A manual override valve is provided that will permit manual selection of fuel enrichment or will shut off the fuel enrichment regardless of the condition of the automatic valve.
Claims13
A fuel feed system for an internal combustion engine comprising a fuel source, a fuel discharge for delivering fuel to said engine, automatic valve means for automatically controlling the communication of said fuel source with said fuel discharge for delivering fuel to said engine in response to a sensed condition, and manually operated valve means for selectively communicating said fuel source with said fuel discharge for fuel enrichment regardless of the condition of said automatic valve means and for precluding delivery of fuel from said source to said fuel discharge regardless of the condition of said automatic valve means for precluding any fuel enrichment.
