Abstract
Since an aspiratoris disposed at a position lower than a fuel galleryand an overflow fuel pipe, DME fuel remaining in the fuel galleryand the overflow fuel pipecan be more efficiently retrieved to a fuel tankby a combined force of gravity and suction force produced in a suction portof the aspirator. Since the vapor-phase pressure delivery pipe opening/closing solenoid valveis disposed at a position higher than the fuel gallery, DME fuel in a liquid state remaining in the fuel galleryand the overflow fuel pipeis forcedly delivered under pressure to the suction portof the aspiratorby a combined force of gravity and the pressure of a vapor phasein the fuel tank. Accordingly, time taken to retrieve the DME fuel in an injection system to the fuel tank after the stop of a diesel engine.
