Quick Answer: What Is A Gami Injector In Aviation?

What are Gami injectors?

GAMIjector® fuel injectors and TurboGAMIjector® fuel injectors are fuel injection nozzles designed to deliver specific amounts of fuel to each individual cylinder that will compensate for the fuel/air imbalance inherent in the fundamental design of the engine fuel/air systems.

What is a saturated injector?

A saturated signal is a simple signal used to operate high impedance injectors. Unlike peak/hold, a saturated injector remains “on” for the entire pulse width. This means that the current flow in the driver and injector circuit stays low keeping the components cool for long life.

What do oversized injectors do?

By putting larger injectors into the truck (usually referred to as “percentage over”), we are able to get that bigger quantity of fuel into the cylinder, keeping the pulse width in a safe zone, and requiring less total injection timing.

How do you clean Gami injectors?

Instructions for Continued Airworthiness and Periodic Maintenance: GAMI recommends removal and cleaning of the nozzles at normal intervals of 100-200 hours. Nozzles may be soaked in an appropriate solvent such as Gunk carburetor cleaner or Hoppe’s #9 Gun Solvent, followed by blowing off with an air nozzle.

What is a good Gami spread?

Most engines are considered to have good fuel/air ratio balance if the GAMI Spread is less than 0.5 gph. While following these test methods, GAMI highly recommends a safety pilot accompany you. We also recommend you keep the cowl flaps open, if so equipped, and you perform the test at 65% power.

What is Gami?

Noun. gami. paternal grandfather, maternal grandmother; a parallel grandparent.

What is injector hold mode?

The peak and hold circuit opens the injector with a high current (Peak) pulse and then switches the current down to hold the injector open. The Peak current quickly opens the injector while the lower Hold current rating is used to keep it open for the duration of the ECU command.

Are high impedance injectors better?

The new technology used in the design and construction of today’s high impedance injectors allows much larger flow rates, much better response times, and much more predictable low pulse width operation than previous designs – all without overheating.

What is a high impedance fuel injector?

High – impedance injectors, also called saturated fuel injectors, are sent a 11-1/2-amp current signal to open, and that current stays on until the injector closes. Low- impedance injectors, also called peak-and-hold injectors, are sent a more powerful electrical signal, usually around 56 amps, to open.

Are bigger injectors better?

Bigger injectors will deliver more fuel, but in petrol engines this means more air is needed to keep the mixture at the best combustion ratio. So if you turbo charge, or supercharge, the bigger injectors will give more power. Otherwise they will decrease power and waste fuel, like running constantly on the choke.

Can you get injectors that are too big?

But yes you can go too big. You can have idle issues and some tuning issues. Too big bad, too small bad. You want a properly sized injector for your setup.

How much HP can fuel injectors add?

Larger throttle body and injectors Depending on what type of engine you have, you can gain as much as 10-20 more horsepower and comparable torque. There is a catch, however. Go too large and you can lose power.
