An engine nacelle for a turbofan engine, having a nacelle wall and an engine inlet, wherein the nacelle wall has a stationary downstream section and an upstream section that is displaceable in the axial direction, and the displaceable upstream section is displaceable between a first upstream position and a second downstream position. A ring-shaped seal is provided, formed between the stationary section and the displaceable section of the nacelle wall, wherein, in the first position of the displaceable section, the engine nacelle forms a ring-shaped additional flow channel that extends from the outer side of the nacelle wall to the engine inlet and via which ambient air can flow into the engine inlet, and the ring-shaped additional flow channel is closed in the second position of the displaceable section, wherein the stationary section, the ring-shaped seal and the displaceable section adjoin each other.
