  • Patent number: 7841762
    Abstract: An apparatus includes a vessel 10 for storing a liquid mixture 11 containing a liquid fuel 2 and an incompatible liquid 4 such as water or for allowing the liquid mixture 11 to flow therethrough, a vibrator 13 having at least one portion making contact with the liquid mixture in the vessel, a vibration generator 20 for vibrating the vibrator at high frequency, and a reflector 14 spaced from the vibrator 13 at a small distance. The incompatible liquid 4 is dispersed in and mixed with the fuel 2 by vibrating the vibrator at high frequency, whereby an emulsion fuel 12 having an ultra fine particle size and high mixture density is produced. According to the above configuration, cavitation can be extremely efficiently generated. The following technique is disclosed: a technique for producing various types of liquid mixture having an ultra fine particle size using the cavitation efficiently.
