Fuel vapor temporary storage device includes a collecting tank which is configured to collect fuel and a temporary storage device is configured to collect gas-phase components that are released from fuel located in the collecting tank. A compressor is configured to supply compressed air to the device. A first line creates a fluid connection between the collecting tank and the temporary storage device. A second line creates a fluid connection between the compressor and the temporary storage device. The temporary storage device receives the gas-phase component via the first line and receives compressed air from the compressor via the second line. The temporary storage device has a third line configured to discharge the collected gas-phase components from the temporary storage device to an internal combustion engine when the compressor is supplying compressed air via the second line.
