GAMIjector Aircraft Fuel Injector


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.

Each GAMIjector® fuel injector is carefully calibrated to much tighter tolerances than standard fuel injectors available for your engine. Our award winning GAMIjector® fuel injectors alter the fuel/air ratio in each cylinder so that each cylinder operates with a much more nearly uniform fuel/air ratio than occurs with any standard factory set of injectors. You will see the difference on your engine monitor with the very first flight! Click here for videos about GAMIjectors: GAMI youtube video play list

Description Technical Specs Information
"Flying The Injected Engine" with Barry Schiff


For many years, pilots and mechanics with a good understanding of the operation of internal combustion engines have known that the fuel/air distribution in our aircraft piston engines has been less than optimal. With the invention of multi-cylinder engine monitors, many pilots started watching an unsettling graphic display of just how far from "optimal" or "uniform" the cylinders were running in their engines.

During a normal lean cycle, such as most pilots routinely perform just after arriving at their crusing altitude, pilots with engine monitors have discovered that the EGT's on the various cylinders will all reach peak at greatly different total engine fuel flows. At cruise power settings, GAMI engineers have seen some engines in which the first cylinder reached peak EGT at, for example, 15 GPH, and the last cylinder did not reach peak until the engine had been leaned to a fuel flow of 13 GPH or less. This "spread" in fuel flows, from the first cylinder to reach peak EGT until the last cylinder to reach peak EGT, is a sure indication of just how unbalanced the fuel/air ratios are between the various cylinders.

Notice in the discussion above, that the important issue is when in the complete lean cycle each cylinder reaches peak EGT, not the absolute value of any particular EGT. Many pilots make the mistake of focusing on the absolute temperature of the individual cylinder's EGT, rather than focusing on the sequential timing when the different cylinders reach their maximum exhaust gas temperature.

STC'd, PMA'd and fully legal.

GAMI has developed and certified specifications for a set of precision fuel injectors for almost all engines in the current Continental and Lycoming fleet of fuel injected engines. We have STCs and PMAs on over 300 different engine models.

These specifications are optimized for each engine model, based on the extensive testing with GAMI's state-of-the-art 96 channel data acquisition system. Data, not "hangar talk"!
