ABSTRACT:
As cold start is initiated in a spark-ignition internal, fuel injection combustion engine, lower molecular weight constituents fo a full-range gasoline are selectively eluted by an elution system including an adsorbent bed of adsorbent material (cold start cycle). Under such circumstances, the adsorbent bed forms an elution zone within a cannister assembly. Entry of the full-range gasoline is initiated by a valve and conduit network under control of a fuel injection control circuit. Furthermore, when the engine is in an inoperative state (vapor capture cycle) the same adsorbent bed is also capable of performing a second function: it adsorbes evaparative emissions originating from within the gasoline tank.
