Zusammenfassung:	The utility model relates to a multipath purging system for an engine. In the example method, the double-path purging system for the engine comprises an ejector, at least one breakpoint and a shutoff valve, wherein the ejector comprises a limiting object, a first inlet, a second inlet and an outlet; the at least one breakpoint is arranged at the limiting object or the inlet; the shutoff valve is connected with the outlet. Therefore, all sections used for monitoring the ejector can be reduced, so that the demand of diagnosing the leakage of the ejector can be met; furthermore, a great deal of sensors needed by monitoring the leakage of the ejector can be reduced.
