Abstract: A control housing module (1) for a combustion engine, with integrating and/or connecting and/or receiving structures for auxiliary components (2,3,4,5,6,7,8) and a rib structure. The control housing module (1) consists of a fibre-plastic composite, which has at least one insert (10) made from a flat fibre textile in a thermoplastic matrix. The rib structure made from injected reinforcing ribs (11,11a) is formed of a thermoplastic, which has short fibres made of a reinforcing material with a proportion by volume of at least 30%. The ribbing (11,11a) includes rib structures (11a) arranged according to the direction of force and regularly formed longitudinal, transverse and/or diagonal reinforcing ribs (11) that cross one another. A foam material is arranged in the spaces (13) between the ribs, the spaces being bordered by the ribs (11,11a).

Abstract: In an internal combustion engine comprising an engine block consisting of a crankcase, at least one cylinder sleeve extending from the crankcase and a coolant jacket disposed around the cylinder sleeve or sleeves and a cylinder head mounted on the engine block, the coolant jacket is a separate component consisting of a material lighter than the normally used cast iron jacket and is firmly engaged between the crankcase and the cylinder head which is mounted onto the cylinder sleeve or sleeves.
