Engine Preservation

[blakecarl]

I’m looking at alternatives for reducing the corrosion that takes place due to moisture in the engine during periods of inactivity. These would be for periods when flying for at least an hour every week doesn’t work out for whatever reason. I ran across a paper describing the construction of a unit that pumps dried air through the engine continuously. The paper is attached. I’m curious what thoughts others have on using a unit of this type and or what others do to preserve the life of their engines.

Here are some specific questions I have. 1) The system is attached to the oil filler and breather tubes. Would dried air get into the cylinders themselves be “leaking” by the piston ring gaps? 2) If dried air does get into the cylinders, wouldn’t you need to plug the exhaust and or intake so that the system remains closed? 3) Along this line of thinking, maybe two units would be the optimum? One hooked up as described in the paper and a second hooked up to a plug hole from each cylinder and the carburetor. 4) The unit construction could be simplified significantly if you had a jar that was large enough to put both the desiccant and the pump into. This would eliminate the need to revise the construction of the pump itself, but would there be a concern for heat build up with the pump within the jar?

Enough of my thoughts, it’s time for others to interject.

Re: Engine Preservation

It appears having DRY air flowing into a cylinder & removing any moisture would be a good thing.

Additional might be better but overkill.
