Abstract
An internal-combustion engine with a device for adjusting the rotational angle (camshaft adjuster ()) of a camshaft () relative to a crankshaft is provided. The device comprises a driving wheel () connected in a rotationally locked way to the crankshaft, a driven part () connected in a rotationally locked way to the camshaft (), and an adjusting mechanism, with which the phase position between the crankshaft and camshaft () can be set and maintained in a certain range of angles. A reduction of the required axial structural space of the camshaft adjuster () and the number of individual parts is achieved in that the driven part () is fixed to the camshaft () with a frictional, positive-fit, or interference-fit connection.
