Abstract

The invention relates to an arrangement of a timing case cover on a reciprocating-piston internal combustion engine, having an engine block (ZKG), a crankshaft pivot-mounted in the engine block, an oil pan which tightly seals the engine block to the bottom, and a timing case cover which is located on the engine block on the front side, which adjoins the engine block via a second, end-side sealing surface, and which has a through opening to rout out the drive torque of the crankshaft for an accessory drive. To achieve reliable sealing and a short structure of the internal combustion engine, the sealing surface of the timing case cover or timing case covers, examined in a side view, is made to run obliquely down to the inside such that on the engine block-side a timing case chamber which decreases in its depth downward is formed.
