摘要： A fuel vapor purging system includes a container in which a set of divided chambers are formed by partition walls. Absorbent is disposed in the divided chambers. The divided chambers are sequentially connected to form a zigzag passage. Fuel vapor can enter the container from a fuel tank via a vapor line connecting the fuel tank and the container. In the container, an end of the vapor line faces the divided chamber which occupies an end of the set of the divided chambers. In the container, the fuel vapor is absorbed by the absorbent. Air can escape from the container via an opening in the container. The fuel vapor can be separated from the absorbent. The separated fuel vapor can be drawn into a suitable drawing device such as an engine air induction device via a purge line connecting the container and the drawing device. Fresh air can flow into the container via an air inlet provided on the container. Among the divided chambers, at least the divided chamber which occupies the end of the set of the divided chambers has a cross-sectional area equal to or smaller than 40 cm.sup.2.

摘要翻译： 燃料蒸气吹扫系统包括容器，其中一组分隔室由分隔壁形成。 吸收剂设置在分隔的室中。 分开的室依次连接形成之字形通道。 燃料蒸汽可以通过连接燃料箱和容器的蒸汽管线从燃料箱进入容器。 在容器中，蒸汽管线的一端面对分隔的室，该分隔室占据了分隔室的一端的一端。 在容器中，燃料蒸气被吸收剂吸收。 空气可以通过容器中的开口从容器逸出。 燃料蒸气可以与吸收剂分离。 分离出的燃料蒸汽可以通过连接容器和抽拉装置的清除管线被吸入合适的绘图装置，例如发动机空气感应装置。 新鲜空气可以通过设置在容器上的空气入口流入容器。 在分隔室中，至少分隔室的占据分隔室的一端的分隔室的截面积等于或小于40cm 2。
