Vapor temperature controlled exhaust gas heat exchanger

摘要: An exhaust gas heat exchanger for vaporizing a liquid fuel is disclosed. The includes flow control valve means, responsive to vapor temperature, the delivery of heated gases coil. A housing communicated with conduit an otherwise conventional internal combustion engine and provided means defining pair generally parallel chambers. fluid conducting assembly, in form one or more helical coils tubing, disposed within said at least two chambers housing. tubing communicates on upstream end source downstream reservoir. coil arranged have maximum surface volume ratio by including plurality individual conduits side relationship. diverter member body operative modulate portion total stream which passes through over assembly. vacuum motor actuates between stops. as engine. position valve, hence member, may be controlled temperature unit senses any desired location.
