PROBLEM TO BE SOLVED: To provide a start system, which is more cost-effective than the known system.SOLUTION: A drive mechanism 1 comprises an engine 3; and a start system 5 which has an output member 7 that is connected to a crankshaft 9 of the engine 3. The start system 5 further includes: a flywheel 11; and connecting means connecting the flywheel 11 to the output member 7. The connecting means comprises a clutch 13; and a gear reduction 15. The start system 5 further comprises a drive source 17 formed by an electromotor which is directly connected to the flywheel 11 or which is connected to the connecting means between the clutch 13 and the flywheel 11. The maximum power that can be delivered by the drive source 17 is just sufficient to maintain the flywheel 11 at the proper r.p.m. If the drive source 17 is turned on, it thus delivers just sufficient power to maintain the flywheel 11 at the proper r.p.m. The maximum power of the drive source 17 is, in this case, 50 W. |
