ultrasonics

[xl650]

I would like to build an ultrasonic fuel vaporizer but have no idea about what I am looking for in a transducer or power supply.Electronics is my weak point.Could the same transducer be used on water?Would adding a heat source help?Maybe someone knows a good book or online school or something for electronic illiterates such as myself.My lack of knowledge in this field is becoming a great hinderance.Thank you for any help
