PURPOSE:To provide plural engine driving devices which are intended to combine higher output performance and lower fuel cost for a vehicle mounted with a main engine constantly driven and a sub-engine temporarily operated depending on the running condition of the vehicle. CONSTITUTION:A main engine 14A is used as a natural suction engine and a sub-engine 14B is used as a supercharging engine equipped with a turbo charger 22, so that the turbo charger 22 can be given rotation by the exhausting operation of the main engine 14A before the sub-engine 14B is started.
