ABSTRACT:
This invention provides means for stopping the flow of gasoline through a gasoline engine during the initiation of starting. In this way the engine contribution of smog forming materials is reduced and the engine is more easily started. This improved starting of the engine is achieved by increasing the portion of the work of compression available to usefully evaporate gasoline. To accomplish these results a stop valve is interposed between the fuel metering system and the fuel delivery jet of the engine carburetor, the valve being so automatically actuated so as to open only after a delay time interval of engine cranking during cold starting. The valve may also be closed automatically whenever the engine ignition is turned off thus assuring a prompt stopping of the engine.
