Ostensibly, the industry has been working since the early 1990s towards finding a solution, but efforts didn’t really get serious until a few years ago. [Read more…]
Recently, my wife and I decided to take a road trip to Texas to visit friends and fill up on good Cajun and Tex-Mex food. On our return, I stopped to visit GAMI — General Aviation Modifications, Inc. — in Ada, Oklahoma.
GAMI builds and sells a line of parts designed to improve performance for a variety of aviation applications. It is best known for GAMI injectors. The concept of the GAMI injectors is to even out the variation in air/fuel ratios for all the cylinders of an engine. This, combined with proper instrumentation, will allow the pilot to operate on the lean side to peak. I know many people think that operating on the lean side is operating on the dark side and can harm the engine. However, if done properly, it can be done with little or no problem. There are several advantages to operating on the lean side, but the biggest is that you can decrease your fuel consumption by a very significant amount.
GAMI’s latest project is to design an unleaded fuel that will satisfy the same engines that presently require 100LL. There are presently three approaches to finding a replacement for 100LL.
