ABSTRACT:
The invention relates to an internal combustion engine (1) with at least one cylinder (2) with a reciprocating piston (4) coupled to a connecting rod (5) for rotating a crankshaft (6), with an engageable gear (8) that is comprised of a first gear shaft (12) that is driven by the crankshaft (6) through a belt-type stepless transmission (7) and of a second gear shaft (15) that is coupled to an intermediate shaft (18) for rotating a drive shaft (9), and with a balancer shaft (20) driven by the crankshaft (6), said crankshaft (6), first gear shaft (12), second gear shaft (15), intermediate shaft (18) and balancer shaft (20) being disposed in one common, multi-piece housing (24). For ease of manufacturing, machining and assembling, there is provided that at least five shafts selected from the group consisting of the crankshaft (6), the first gear shaft (12), the second gear shaft (15), the intermediate shaft (18) and the balancer shaft (20) be disposed in a first parting plane (21) of a first and a second housing piece (22, 23) of the housing (24).
