Pintle-regulated Venturi Fuel Induction Systems

PRV induction, with fuel injection directly at the Venturi throat, effectively mixes fuel and air due to the high velocity and reduced pressure at the vapor-liquid contact region, while pressure is recovered in the expansion section. Fuel vaporization in the confined Venturi volume amplifies air flow into the PRV entrance.

A PRV is a...

  • Throttle
  • Fuel Injector
  • Mixer
  • Intercooler

...all in one device!

How does a PRV work?

  • Air enters the contoured Venturi via an air filter.
  • Fuel vaporizes and expands in the low pressure throat.
  • Fuel vaporization induces air flow into the Venturi entrance.
  • Fuel vaporization in confined space thrusts mixed charge into the engine.
  • Charge is always homogeneously mixed and cooled because the pintle regulates air flow at the confluence of fuel and air.
