Abstract
A length-adjustable connecting rod for an internal combustion engine, comprises a first connecting rod member, a second connecting rod member and at least one cylinder-piston assembly for adjusting the first connecting rod member relative to the second connecting rod member. The cylinder-piston assembly can be actuated by way of a hydraulic adjustment mechanism, where the hydraulic adjustment mechanism comprises at least one oil filter in order to filter the engine oil of the internal combustion engine flowing into the cylinder-piston assembly. The invention further relates to an internal combustion engine with such a length-adjustable connecting rod and the use of such a cylinder-piston assembly for a length-adjustable connecting rod of an internal combustion engine.
