In-line engine with variable compression, comprising a cylinder receiving section which is tiltably mounted in the crankcase section (4) of the engine, in which the crankshaft is mounted by means of 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 lateral parts (104,106) of the crankcase section. These transversely connecting bearing caps rest at their outer end (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 are securing in the crankcase section (4) 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. |
