AeroInjector 32 shown above with flange mount and optional Intake Flange Adapter

Simplicity in form and function! Utilizing what hydraulic and pneumatic engineers call the "perfect flow passage" the AeroInjector (formerly known as AeroCarb) achieves outstanding performance versatility! AeroInjector body parts are precision machined from solid 6061 aluminum billets.

There are only two moving parts... no float bowls or secondary jets to complicate things. A fine adjustment metering needle provides clean burning, smooth running, outstanding response, and fuel economy. Spigot or flange mounts easily adapt to popular aircraft and auto conversion engines. AeroInjector's intake design accepts air filters or carb heat ducts.

The AeroInjector is included as standard with all AeroVee engines, and is highly recommended to replace the Bing carb that ships with Jabiru engines.

To read about AeroInjector performance and fuel economy with the Jabiru 3300 engine, read "The $35 Hamburger" by Sonex's own Kerry Fores, or check-out our AeroInjector FAQ's. See Fuel Burn and Economy Data with AeroCarb/AeroInjector-equipped Sonex Aircraft.

AeroInjectors have been successfully installed in everything from Continentals and Lycomings to Chevy's and Suzuki's

The AeroInjector is available in 2 sizes and with any combination of spigot (top left) or flange (left) intake manifold and air box/air filter mounts, serving engines producing 30-125 horsepower.

AeroInjector Features
  • Works in up-draft, side-draft, and down-draft configurations.
  • Gravity feed... no fuel pump required.
  • Fast, dependable starts.
  • Resistant to icing: no butterfly valve to accumulate ice; no true venturi to super-cool the mixture; fuel atomizes downstream of the injector, in the engine's warm intake manifold.
  • No float bowl. Great for aerobatics!
  • Only 2 moving parts.
  • Easy to tune... only 1 adjustment.
  • 3 metering needles included.
  • Detailed Installation Manual included.
  • Integral cockpit-controlled mixture and fuel shut-off.
  • Mixture cable mount built-in.
  • Accomodates "pull-type" reversing throttle quadrants.
  • Precision CNC billeted 6061-T6 aluminum construction.
  • Spigot (hose) or Flange mount (std. 4 hole).
  • Model sizes available: 32mm, & 35mm, servicing engines 30-125 hp. (38mm AeroCarb has been discontinued)

Compatible Fuel Systems:

Most Fuel Systems can work with the AeroInjector’s “no float” design:
1) Gravity Feed
2) Fuel pump System
3) Return System
4) Header Tank System

1) Gravity Feed: A gravity feed system is by far the safest and most reliable. The AeroCarb/AeroInjector requires very little head pressure to operate effectively.

2) Fuel Pump System: If your aircraft requires a fuel pump (ie: wing tanks or pusher engines) a fuel pressure regulator must be installed to limit fuel pressure to about 1 or 2 lbs.
3) Return System: A fuel line “T” is installed between the regulator and the injector with a return line to the tank. This will supply the injector fuel without excessive pressure. Excess fuel will return to the tank.
4) Header Tank: Pumping fuel from the main tank(s) to a small header tank mounted above the injector will provide gravity feed to the injector. A return line from the header to the main tank(s) is required. This type of system assures some reserve fuel in the event the fuel pump fails and eliminates the need for a fuel regulator

Your fuel system must be able to deliver 1.5 times the engine’s required fuel flow at full throttle.
