Abstract
A simplified and improved cold enrichment device for an internal combustion engine. The device includes a valve that controls communication of a fuel source with a cold starting enrichment port and which valve is operatively connected to a pump for pumping additional fuel to the engine upon movement of the valve from a normal condition to a cold enrichment position.
Claims15
In a starting fuel system for an internal combustion engine comprising a fuel source and cold starting enrichment means for supplying fuel from said fuel source to said engine including control means movable between a normal position wherein said cold starting enrichment means does not provide fuel from said fuel source to the engine and a cold enrichment position for supplying fuel from said fuel source to the engine, the improvement comprising means coupled mechanically to said control means so as to be responsive to movement of said control means from its normal position to its cold enrichment position for supplying a charge of additional fuel from said fuel source to the engine for starting simultaneous with movement of said control means from its normal position to its cold enrichment position.
