Abstract

The invention relates to an internal combustion engine having a cylinder head with a cam drive, which has a rocker arm pivotably supported in the cylinder head. A roller is supported in the rocker arm in which the roller rolls on a cam path of a cam of a camshaft and is intended for the drive of reciprocating components. The roller is supported in the rocker arm on a roller bolt which on at least one face end has a bore leading to the bearing point of the roller, to which bore lubricant can be delivered on the face end upon execution of a reciprocating motion by a lubricant delivery device associated in the region of the reciprocation path executed by the bore.
