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.

Reciprocating piston machine and method and device for diagnosing and/or controlling a reciprocating piston machine

The invention relates to a longitudinally adjustable connecting rod () for a reciprocating piston engine, in particular a reciprocating piston internal combustion engine, a reciprocating piston engine, and a vehicle comprising a reciprocating piston engine. The longitudinally adjustable connecting rod () comprises a longitudinal adjusting mechanism () for adjusting an effective length (L) of the connecting rod, a hydraulically actuated control device (), switchable at least between two control modes, for controlling the longitudinal adjustment, and an electromagnetically actuated hydraulic switching valve () for hydraulically actuating the control device ().
