ABSTRACT:
An automotive type diesel engine provided with a conventional fuel filter water separator has a solenoid operated drain or dump valve for removing liquid contaminant/water automatically when the contaminant or water reaches a predetermined level actuating a sensor. The removed contaminant or water is then inducted into the engine by means of a venturi/aspirator which in one embodiment has an outlet connected directly to the engine intake manifold to provide the necessary pressure drop or, in another turbocharged diesel engine embodiment, the boost pressure is connected to the inlet of the venturi/aspirator to again induct the liquid contaminant/water into and through the aspirator to be disposed of in the exhaust system of the engine, both embodiments thereby automatically providing for a complete disposal of liquid contaminant/water within the engine and thereby eliminating the need of a periodic draining of the same from the fuel filter by the vehicle operator, for example.
