Abstract
Abstract In a motor vehicle driven by an internal combustion engine (1), the fuel vapors escaping from the fuel tank during filling are trapped in a can (6). The can is accommodated in a recess in the base of the spare wheel container. In this way, a comparatively large can may be accommodated without the need for extra space.
