Abstract
An internal combustion engine with variable compression which includes a cylinder receiving section which is tiltably mounted to a crankcase section (4) of the engine, and a crankshaft (12) which is mounted in the crankcase section via crankshaft bearings (90) arranged in the lower region of the crankcase section (4). The crankshaft bearings incorporate bearing caps (102) which constitute continuous stiffening transverse connecting elements between the lower later parts (103,106) of the crankcase section. These transversely connecting bearing caps rest at their outer ends (108, 110) against internal surface areas in the lower lateral parts (104, 106) of the crankcase section on both sides of the engine. The bearing caps (12) are secured in the crankcase section (40) not only by means of vertical crankshaft bearing screws (112, 114) but also by means of screwed joints (166, 118, 120) which connect the lower lateral parts to the outer ends (108, 110) of the bearing caps.
