Patent attributes
A supercharged internal combustion engine includes an intake tract and a throttle element. Between the compressor and the throttle element, the intake tract is gas-conductively connected on the low-pressure side to a first line and on the high-pressure side to a second line via an overrun air recirculation valve. A fuel tank having an activated carbon filter is provided for supplying fuel to the internal combustion engine, the fuel tank being gas-conductively connected via a valve to a tank venting valve. Between the compressor and the throttle element, the intake tract is gas-conductively connected on the low-pressure side to a third line and on the high-pressure side to a fourth line via the tank venting valve. The overrun air recirculation valve and the tank venting valve are arranged in parallel in terms of flow and the first and third lines and the second and fourth lines are, at least in sections, the same lines.
