ABSTRACT:
The invention is directed to a multi-engine drive system with at least two engines which have a common crankshaft. In order to test if both engines are operating properly, a mutually oppositely directed modulation of the throttle flap angles of the throttle flaps is caused by a control unit to occur periodically in the context of a test function. If this test function causes a change in the rotational speed of the crankshaft, then this means that the two engines are no longer operating symmetrically so that a disturbance is present. In this way, a continuous monitoring of the operation of both engines is provided.
