Abstract

The invention relates to a device for mounting two camshafts in the cylinder head of a multi-cylinder in-line internal combustion engine having especially four valves per cylinder, the device comprising bearing housings supported on the cylinder-head housing. To make it possible to provide a cylinder head with small valve angles and with more than four cylinder-head screws per cylinder, the bearing housings are accommodated in a camshaft bearing frame consisting of longitudinal and transverse webs and produced separately from the cylinder-head housing.
