Engine liquid injection

摘要

A device capable of collecting a condensate from a working fluid is disclosed. The condensate can take the form of a liquid and can be injected into a flow path of an engine. In one form the engine is a gas turbine engine and the liquid is injected upstream of a combustor. The liquid can be produced using a component that cools the working fluid to condense a vapor within it. In one non-limiting form the component is part of a refrigeration system. In addition to producing condensate, the refrigeration system can cool the working fluid to be used as cooled cooling air to a turbine of a gas turbine engine. In another non-limiting embodiment a liquid derived from a blackwater containing waste from an organism can be delivered in whole or in part to a flow path of the engine.

主权项

1. An apparatus comprising:
a vehicle having an internal combustion engine and a fluid flow path leading from an intake to a combustion chamber and to an exhaust; an extraction flow passage structured to withdraw working fluid from a location upstream of the combustion chamber and downstream a compressor; a cooling system having a heat exchange member structured to cool the extracted working fluid, the extracted working fluid including a vapor; and a liquid flow path in communication with the fluid flow path of the internal combustion engine and structured to convey a liquid condensed from the extracted working fluid via the heat exchange member and route the liquid into the compressor; wherein the working fluid is cooled by the heat exchange member and is routed subsequent to the heat exchange member to a turbine thereby cooling the turbine.
