Abstract
Fuel injectors of varying modes, shear or thickness, and megahertz are used to reduce the size of fuel droplets. The fuel injector has an expansion chamber and an orifice-containing face plate with a porous PZT material arranged adjacent to the face plate. The fuel passes through the porous PZT material as the PZT material is energized to realize reduced fuel particle size.
Claims11
A method using ultrasound to reduce the size of fuel droplets comprising:
- providing a fuel injector having an expansion chamber and an orifice-containing face plate with a porous PZT material arranged adjacent to the face plate passing fuel through the porous PZT material as said material is energized;
- and
- maximizing ultrasound standing waves impacting the fuel droplets generated by said energized PZT material to reduce fuel droplet size.
Dependencies are inferred from the claim text.
