Abstract
The invention relates to a reciprocating piston engine, in particular an internal combustion engine, comprising at least one length adjustable connecting rod () connected to a crankshaft (), which connecting rod () comprises at least one first rod part () having a small connecting-rod eye () and at least one second rod part () having a large connecting-rod eye (), which two rod parts () can be displaced telescopically with respect to and/or into each other by means of a length adjustment device (), wherein the length adjustment device () can be fluidically connected in at least one position of a control valve () to at least one oil pressure line (), and can be separated from the oil pressure line () in at least one second position of the control valve (), wherein the control valve () can be electrically switched and inductively actuated. In order to allow the compression ratio to be flexibly changed in a way that is as simple, space-saving and reliable as possible, the control valve () can be electrically connected to at least one induction device () fixed to the connecting rod, in which an electrical current can be induced in at least one position of the connecting rod () by means of at least one magnet device () fixed to the crank housing or crankshaft.
