摘要： A liquid tank such as a liquid fuel tank, as well as a method of operating such a tank and a structure for implementation in such a tank, are disclosed. In at least one embodiment, the liquid tank is a liquid fuel tank that includes a housing have an inner chamber capable of containing liquid fuel as well as an air space above an upper surface of the liquid fuel, and a floating member included within the inner chamber, where the floating member is configured to float proximate the upper surface of the liquid fuel when the liquid fuel is present within the inner chamber. The floating member includes at least one tapered surface, and the floating member covers a majority of the upper surface of the liquid fuel, whereby the liquid fuel evaporates to a lesser degree than would occur if the floating member was absent.

摘要： A primer assembly is provided for use on a carburetor that is vented through an external vent on the primer. In at least some embodiments, the assembly comprises a housing comprising an open end and an outlet with a flexible primer bulb inserted into and closing the open end of the housing, thereby defining a volume within the housing. There is a vent in the primer bulb. A carbon canister is positioned within the volume defined in the housing such that the vent and the outlet are in fluid communication via a flow path that extends through the canister. The carbon canister adsorbs fuel vapors from the carburetor. During normal operation of the engine, air enters through the primer vent and purges the carbon canister of the adsorbed fuel.

摘要： A system and method of controlling/adjusting purge flow rate in an internal combustion engine is disclosed. The system includes an air intake assembly, a fuel tank assembly and an evaporative emissions control device such as a carbon canister in operational association with each other. Fuel vapors from the fuel tank assembly flow into the evaporative emissions control device for adsorption. The adsorbed fuel vapors from the evaporative emissions control device are recovered, at least in part due to pressure differentials, and actively purged into the internal combustion engine. The purge flow rate from the evaporative emissions control device is controlled/adjusted by a flow control device, the flow control device that is at least indirectly connected to the evaporative emissions control device and the air intake assembly. In one aspect, the flow control device can comprise an orifice device, such as, a connector device having at least one orifice for regulating purge flow rate. In another aspect, the flow control device can comprise a filter device for cleaning the intake and/or purged air in addition to regulating the purge flow rate.
