A plurality of internal combustion engines (1, 2) are installed independently from one another, at least one internal combustion engine (1) is constantly connected to an output shaft (11) as a main power source, the other internal combustion engines (2) is connected through a clutch (15) to the output shaft (11) as an auxiliary power source, and the engaging timing of the clutch (15) is matched to the driving period of the main and the auxiliary power sources by a rotational speed detector for detecting the rotational speed of the main and the auxiliary power sources and a phase detector for detecting the phases of both the main and the auxiliary power sources. |
