In response to our call for innovations, Jerry Olson wrote to tell us about the engine dehydration system he developed, which he says removes virtually all the moisture from inside aircraft engines.
“Removing this moisture should prevent many of the corrosion induced failures that many GA aircraft engines experience, saving those aircraft owners from overhauling their engines prematurely,” he says.
“I developed this dehydration system due to a corrosion-induced cam failure in the Lycoming IO-360 engine in my Cardinal RG,” he continues. “After graphing and analyzing the data from my oil analysis, it was apparent this failure was likely due to the high humidity levels where I live in Houston, Texas. After overhauling my engine due to this cam failure, I decided I needed a system to keep my engine dry.
“The end result is a very capable system. So much so, that numerous other aircraft owners have asked me to build systems for them. This has led to building nearly 50 systems in the last year. And, due to the systems uniqueness, I was awarded a complimentary booth in AirVenture’s Innovations Center this year.”
- Microprocessor controlled and fully automatic;
- Measures and digitally displays the relative humidity from inside the engine;
- Recirculates the engine air in a closed loop that progressively dries the air;
- Reduces and maintains the relative humidity inside the engine to below 10% on a continuous basis;
- Prevents outside humidity from re-entering the engine;
- Dynamically adjusts to relative humidity changes inside the engine and to changes in the weather;
- Actively removes virtually all moisture from inside the entire engine;
- Dries air inside the intake, the exhaust, the combustion chambers and the crankcase;
- Removes residual moisture from the oil, minimizing acid formation;
- Small, portable, and energy efficient;
- Can be used on aircraft tied-down outside, when powered by a small battery and solar panel.
