Abstract
A cold start fuel control system provided for use with an internal combustion engine of the type having at least one combustion chamber, an air/fuel passageway fluidly connected with the combustion chamber and the source of fuel. The fuel control system includes an annular heater having an interior annular wall disposed within the passageway. A cold start fuel injector has its inlet fluidly connected to the fuel source and an outlet open to the passageway such that fuel from the outlet flows into the interior of the heater. Whenever the operating temperature of the engine is below a predetermined level, fuel is selectively provided to the cold start fuel injector which injects fuel into the passageway. The fuel discharge from the cold start fuel injector is swirled so that at least a portion of the fuel from the cold start fuel injector impinges upon the annular heater and is thus vaporized.
