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 (3) is disclosed. The system includes an air intake assembly (4), a fuel tank assembly (6) and an evaporative emissions control device such as a carbon canister in operational association with each other. Fuel vapors from the fuel tank assembly (S) flow into the evaporative emissions control device (8) for adsorption. The adsorbed fuel vapors from the evaporative emissions control device (8) are recovered, at least in part due to pressure differentials, and actively purged into the internal combustion engine (3). The purge flow rate from the evaporative emissions control device (8) is controlled/adjusted by a flow control device (40), the flow control device (40) that is at least indirectly connected to the evaporative emissions control device (8) and the air intake assembly (4). In one aspect, the flow control device (40) 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 (40) can comprise a filter device for cleaning the intake and/or purged air in addition to regulating the purge flow rate.
摘要翻译：公开了一种控制/调节内燃机（3）中的吹扫流量的系统和方法。该系统包括进气组件（4），燃料箱组件（6）和诸如碳罐的蒸发排放控制装置，其彼此可操作地相关联。来自燃料箱组件（S）的燃料蒸汽流入蒸发排放控制装置（8）以进行吸附。来自蒸发排放物控制装置（8）的被吸收的燃料蒸汽至少部分由于压差而被回收，并被主动地吹入内燃机（3）。来自蒸发排放控制装置（8）的吹扫流量由流量控制装置（40），至少间接连接到蒸发排放控制装置（8）的流量控制装置（40）和进气总成（4）。在一个方面，流量控制装置（40）可以包括孔装置，例如具有至少一个用于调节吹扫流量的孔的连接器装置。在另一方面，流量控制装置（40）可以包括除了调节吹扫流量之外还用于清洁进气和/或净化空气的过滤装置。
