A device for precipitating fuel from the vapor discharging from the fuel supply system of an internal combustion engine in which the fuel tank and the mixture-forming system, especially the carburetor float chamber, is connected through pipe lines to a chamber sealed to the atmosphere and defined by the volume of the intake air filter. A filter insert is placed ahead of the air intake and has a layer of activated carbon which absorbs the fuel particles from the vapor passing through the filter. The intake air filter is also provided with an exhaust-connecting piece which is connected to the suction side of a blower exhausting into the atmosphere. The blower is driven by an electric motor which is supplied with power through a contact provided in the starting-ignition switch and a time-control element which automatically interrupts the current supply to the blower motor after a predetermined time period. |
