Abstract
An internal combustion engine (10) is designed with a cylinder section (11) which is pivoted on a crankcase section (13) to provide different compression ratios. The crankcase section (13) is provided with raised lateral walls (21, 22, 24, 25) with upper surfaces (82-85), which lie in the same plane and thereby allow simple assembly of a seal (34) between the cylinder section (11) and crankcase section (13). The lateral walls (21, 22, 24, 25) also enable auxiliary devices for the engine to be easily secured without having to allow for the mobility of the cylinder section (11) relative to the crankcase section (13).
