Abstract
A mist forming method using a fluid injection valve formed of a valve seat, a valve body, and a nozzle portion or an injection hole plate having injection holes, and configured to turn in-hole flows and flows immediately below the injection holes into substantially liquid film flows. Directions of jets from the injection holes are not necessarily brought into coincidence with a center axis direction of the injection holes and are not necessarily crossed with one another in a downstream part, and after the jets turned into mists at a position downstream of a break length position, the mists are allowed to come close or gather by the Coanda effect so as to appear substantially as one solid mist, and allowed to keep gathering until catching of ambient air and a resulting air flow along a downstream flow direction in a predetermined in-mist portion attenuate.
