ABSTRACT:
A liquid vaporizing attachment is provided for a combustion engine including an air and fuel charge forming device defining an air and fuel passage extending therethrough, an induction passage inlet end for receiving an air and fuel charge from the charge forming device and an engine exhaust system. The attachment defines an intermediate passage extending therethrough including inlet and outlet ends communicated with the outlet end of the air and fuel passage and the induction passage inlet end, respectively. The intermediate passage includes heating structure operatively associated therewith for heating fluid flowing therethrough and liquid vapor injection structure for injecting a heated liquid vapor into the intermediate passage. The intermediate passage includes a horizontal major length portion thereof and upwardly and downwardly opening inlet and outlet end portions, respectively, defining the inlet and outlet ends of the intermediate passage. In addition, the intermediate passage defines a main passage and a bypassage for bypassing the central portion of the main passage. The heating structure includes first heating structure in the intermediate portion of the main passage and second heating structure in the bypass passage, the intermediate portion of the main passage including structure for selectively opening and closing the intermediate portion of the main passage to the flow of fluid therethrough.
