Patent ID: 7866424

Claim:
A hybrid vehicle, comprising: an internal-combustion engine; an electric motor; a fuel tank; a tank ventilation pipe that leads from the fuel tank into the environment; a first valve device incorporated into the tank ventilation pipe for selectively opening or shutting off communication between the fuel tank and the environment; a filtering device that can be regenerated, the filtering device being arranged in the tank ventilation pipe between the fuel tank and the first valve device; a suction pipe leading from the filtering device to an intake path of the internal-combustion engine; a second valve device arranged in the suction pipe between the filtering device and the intake path; a control device constructed such that, for flushing the filtering device, the control device actuates the first and second valve devices whereby ambient air can be fed through the tank ventilation pipe, the filtering device and the suction pipe to the internal-combustion engine and, as a result, hydrocarbons present in the pipes and in the filtering device can be fed to the internal-combustion engine for combustion; and the control device is further constructed such that, in an electric operation of the hybrid vehicle, the control device switches on the internal-combustion engine as a function of a loading condition of the filtering device.
