VAPOR INJECTION SYSTEM ENABLING LONGER-HOUR INJECTION WITH PLURAL TYPES OF LIQUID GAS FUEL OF NON-SOLUBLE TO EACH OTHER

摘要

PROBLEM TO BE SOLVED: To provide a vapor injection system capable of injecting vapor continuously for longer hours while restricting cavitation.SOLUTION: A vapor injection is started from a state in which pressure in a space storing vapor within liquid storing segments is higher than saturation vapor pressure of any one of two or more kinds of liquids by a vapor injection system comprising: liquid storing segments 2A, 2B separately storing two or more kinds of liquids non-soluble to each other; injection ports 8 for injecting vapor generated through vaporization of two or more kinds of liquids within the liquid storing segments; and injection control segments 7A, 7B and 7C for controlling vapor injection from the injection ports. Or, a vapor injection may also be started from a state in which pressure in a space storing vapor within fluid storing segments is higher than saturation vapor pressure of liquid by another vapor injection system comprising: fluid storing segments for storing one type of liquid and at least one type of inert gas of which composition is different from the liquid; similar injection ports; and an injection control part.
