Abstract
A device for adjusting the effective length of a connecting rod for an internal combustion engine, includes at least one connecting rod which has a variable length and which can be locked in at least two length settings, at least one first oil pump for supplying oil to the at least one connecting rod with a variable length, and a control unit which provides for a switchover between the length settings of the connecting rod in the event of a change in the oil supply pressure for the connecting rod. The aim of the invention is to shorten the switching times during a switchover between the length settings of the connecting rod. A method for providing such a device for adjusting the effective length of a connecting rod is also provided.
