A connecting rod for changing a compression ratio of an internal combustion engine includes a connecting rod head, a connecting rod pin, and an interlock. The connecting rod pin is supported by an eccentric of the connecting rod at a variable distance within the connecting rod head. The connecting rod head or the connecting rod pin includes a fluid chamber and the eccentric has a projection extending into the fluid chamber. In the alternative, the eccentric delimits a fluid chamber and the connecting rod head or the eccentric has a projection extending into in the fluid chamber. A fluid pressure in the fluid chamber exerts a force on the projection to change the position of the eccentric. In a locking position, the interlock inhibits rotation of the eccentric relative to the connecting rod head and the interlock is configured to be releasable.

Connecting rod for changing a compression ratio of an internal combustion engine

The connecting rod head includes at least one oil chamber and an eccentric comprises a protrusion reaching into the oil chamber, so that an oil pressure in the oil chamber exerts a force on the protrusion to change the eccentric setting of the eccentric.
