Abstract
An internal combustion engine with an adjustable compression ratio has connecting rods (), each of which has a hydraulically adjustable eccentric adjustment device arranged in a connecting rod bearing eye () and/or in a crankpin bearing eye () for adjusting an effective connecting rod length (l) of the respective connecting rod (). Travel of the eccentric adjustment device is controlled by a switchover valve (). Each switchover valve () has a pick-off means (). The switchover valves () can be actuated by an actuation device () that has a switching fork () for each switchover valve () and thus for each pick-off means () to be actuated. The pick-off means () and the switching forks () are oriented relative to one another so that inertial forces acting during driving assist the actuation of the switchover valves () by the actuation device ().
