A clutch device transmits a torque between a rotatable drive-input element and a rotatable drive-output element. Upon demand, the elements are coupled in non-positively locking fashion by a clutch element. Each of the drive-input element and the drive-output element form one clutch surface. A clutch gap decreases in a radial direction relative to at least one axis of rotation of the elements. The clutch element can be placed into a first position and into a second position which differ with regard to the radial position within the clutch gap and thus with regard to the contact pressure between the clutch element and the clutch surfaces. The clutch device permits an axial arrangement of its components, namely, the drive-input element, the clutch elements and the drive-output element, that keeps the size of a clutch device small in a radial direction relative to the axes of rotation.

Clutch device and switching device

An internal combustion engine includes working cylinders and a fresh gas line for supplying fresh gas to the working cylinders. The fresh gas line has a charge air section. A mechanically driven compressor is disposed in the charge air section of the fresh gas line. An air control/shut-off flap is disposed in the charge air section such that, in dependence on a position of the air control/shut-off flap, a gas mass flow in the charge air section flows completely or partially via the mechanically driven compressor or flows past the mechanically driven compressor. A method for operating an internal combustion engine is also provided.

Internal combustion engine including a booster

An internal combustion engine which operates in accordance with an auto-ignition principle includes at least one working cylinder, at least two inlet valves per working cylinder and at least one outlet valve per working cylinder. The internal combustion engine has a first camshaft and a second camshaft. The second camshaft actuates at least one of the inlet valves per working cylinder and actuates at least one outlet valve per working cylinder. The internal combustion engine has an adjuster disposed at the second camshaft. The adjuster adjusts valve control times of the inlet and outlet valves actuated by the second camshaft selectively in an early direction and a late direction in relation to valve control times of the first camshaft. A method for operating an internal combustion engine is also provided.

A support arrangement for the open area of a crankcase facing an oil pan in an internal combustion engine has a plate-like component which is attached to the crankcase walls by lugs, thereby reinforcing the housing, and contains integral bearings rotatably supporting a balance shaft.
