<p>A cold start fuel control system is disclosed for use with an internal combustion engine having at least one combustion chamber (32), a source of fuel (44) and a primary intake manifold (34) having an inlet (38) and an outlet (40) and fluidly connected between the fuel source and the combustion chamber (32). The system includes a cold start fuel injector assembly (52) having an inlet and an outlet with the inlet being fluidly connected to the fuel source (44). An auxiliary intake manifold (54) has an interior chamber (62) which is fluidly connected with each combustion chamber (32). The outlet from the cold start fuel injector is then fluidly connected to the auxiliary intake manifold (54) so that, upon activation of the cold start fuel injector assembly (52), a fuel/air is inducted from the cold start fuel injector, through the auxiliary intake manifold (54) and into the engine combustion chambers. Optionally, the cold start fuel injector assembly as well as the auxiliary intake manifold is heated to enhance the vaporization of the fuel prior to induction into the combustion chambers.</p> |
