The invention relates to an internal combustion engine having a fuel tank (), a tank ventilation line () and a Venturi nozzle () disposed in a fluid-carrying component (), wherein the Venturi nozzle () has an inflow channel (), an opening point () adjoining downstream of the inflow channel () with a fluid connection to the tank ventilation line (), and an outflow channel () adjoining downstream of the opening point (). In this case, an outflow section () of the Venturi nozzle downstream of the opening point () is surrounded by the component () in such a manner that a detection space () is formed around the outflow section (), wherein the detection space () has at least one inlet opening () via which the detection space () can be pressurized and wherein at least one pressure sensor () for monitoring the pressure in the detection space () is provided.

An adjustment mechanism for an air inlet flow section of a compressor wheel of a turbocharger. The adjustment mechanism defines a variable inlet diameter for an axial air flow to the compressor wheel. The adjustment mechanism has a unison ring and a plurality of vanes. An actuator is used for providing a first pivoting motion to the unison ring about a central axis and thereby providing a second pivoting motion to the plurality of vanes. At least one elastic biaser is arranged, such that it provides, upon the pivoting motion to the unison ring, a restoring force to the unison ring and/or the plurality of vanes. The pivoting motion of the vanes adjusts the inlet diameter of the axial air flow to the compressor wheel.
