A length-adjustable connecting rod for an internal combustion engine, where the connecting rod includes at least one switchable outlet valve for opening and closing a pressure chamber, where the outlet valve comprises a valve body and a closing body that is operatively connected to the valve body, and a closing mechanism is present acting upon the closing body for directly moving the closing body and indirectly moving the valve body from a closed to an open position or vice versa. Such an outlet valve is to be configured to be operable. For this purpose, this closing body has a mass which is smaller than the volume defined by the envelope contour of the closing body multiplied by the density of steel (7.85 g/mm). The use of such a closing body for a respective length-adjustable connecting rod is also provided.

The invention relates to a reciprocating piston machine, in particular with a variable compression ratio, of at least one cylinder with a piston and a connecting rod which is connected to the piston and to a crankshaft of the reciprocating piston machine. The reciprocating piston machine also has a first sensor which is arranged in a cylinder wall of the at least one cylinder and is configured to detect relative movement between a piston skirt of the piston and the cylinder wall. The invention further relates to a method () for diagnosing and/or controlling such a reciprocating piston machine (), in particular with a variable compression ratio, and a system which is suitable therefor.
