A compressor wheel for an internal combustion engine may include a plurality of blades which in a circumferential direction of the wheel are spaced from one another. The plurality of blades may respectively include an inflow edge which during operation are subject to an inflow of a compressible fluid substantially axially to the wheel axis. The plurality of blades may include a surface layer of locally distinct materials to adapt to locally distinct loads during operation.

A method for adjusting a barometric cell may include coupling the barometric cell to a control device via an actuating rod. The actuating rod may be movably mounted on a charging device in any desired position. The method may include applying a freely selectable pressure to the barometric cell so as to bring the actuating rod into contact with a stop, adjusting the barometric cell until a sensor registers a predefined value, and fixing the barometric cell on the charging device.

A piston for an internal combustion engine, having a piston base body, a piston ring element having at least an inner region of a piston crown, and a piston skirt. The piston is provided with pin bosses having pin bores and the ring element has at least an outer region of a piston crown having a circumferential top land and a circumferential ring belt provided with ring grooves. The piston base body and piston ring element are joined together by way of corresponding, conical joining surfaces configured on them.
