Bathes the interior of your
engine with low humidity air preventing the formation of rust. Reduces damage to internal
engine parts. Helps reach TBO

not require FAA approval.
Microprocessor controlled,
incorporates sensors for measuring temperature and humidity of
the outside air
Aircraft owners know that an aircraft not flown
regularly is subject to rusting of the internal engine parts. This
rust causes engine wear and shortens engine life. Water
collects in the engine from two sources. First, moisture is a byproduct of
combustion. When you shut your engine down, the crankcase is filled
with hot gasses containing a high percentage of moisture. As the engine cools, this moisture condenses and
water forms. ( This is why you see water droplets on the
dipstick cap when checking the oil level.) Secondly,
daily changes in temperature, humidity, and barometric pressure force moist air
into the engine. Cool evening temperatures then cause this moist air
in the engine to condense forming droplets on the precision engine parts. Over
time this moisture leads to RUST. Cool air temperatures
that occur in the early morning cool the metal engine parts.
Whenever the temperature of the metal parts falls below the dew
point temperature of the moist air inside the engine, water droplets
form. If you can reduce the humidity
level of the air inside the engine, (lower its dew point temperature below the
outside air temperature,) you can prevent water
from ever forming on the engine parts. This is what the Engine Saver does. Oil companies
spend millions on developing additives to protect the engine parts
from the water droplets and prevent rust formation. However, the
best way to protect your engine from internal rust is to prevent
moisture from forming in the first place.- No water, No rust!
The Engine Saver is an electrically powered
device that produces a constant supply of very low humidity, low
pressure air. This low humidity air is then introduced into the
engine crankcase through the breather. The system builds up a slight pressure in the crankcase.
this fills the crankcase with dry air, and the pressure forces the
dry air past the piston ring end gap, into the top cylinder area,
and finally out an open intake or exhaust valve. The system bathes the entire
internal surfaces of the engine with low humidity air preventing the
formation of water.
The Engine Saver consists of a 110VAC
electrically powered low pressure air pump, a chemical dehumidifier which
absorbs the moisture from the air passing through it, and a special
adaptor for introducing the dry air into the engine. The
components are conveniently
mounted on a metal base with integral handle for easy carrying.
A four ft. tube with the special adapter is supplied to fit into the
engine breather tube where it extends from the bottom of the cowl.
The adapter is fitted with a series of foam disks that easily shape
to fit most engine breather tubes.
The updated Smart Engine Saver is a
microprocessor controlled unit that has been designed to provide
good engine protection while maximizing the useful time before
the chemical dryer has to be recharged. The Smart Engine Saver
is easy to use. At the end of a flight, simply push the Engine
Saver adapter into the end of the engine breather tube where it
extends from the bottom of the cowl, and plug the unit into a
standard electrical outlet. When initially turned on, the Smart
Engine Saver will run continuously for one hour. This hour of
operation will purge the moist gasses from the crankcase, and as
the engine cools, prevent the formation of water from the
combustion byproducts. It also establishes a dry environment
within the entire engine. After the initial one hour operating,
the system starts the monitoring mode. The electronics measure
the temperature and humidity levels of the outside air, and
based on this determine how long to turn the pump on. in order
to achieve good engine protection while maximizing the operating
life of the chemical dryer material. On hot humid days, it
operates the pump for longer times. On cold dry days, it
operates it less. The
system consumes only 3 watts of power and can run for a full month
for less than a dollar.
The dryer assembly efficiently removes moisture
from the air. The dew point of the air leaving the dryer can be lower than -100 degrees F. This means that the temperature
of the metal engine parts would have to drop lower than 100
degrees below 0 F before moisture would form in your engine. The
system is designed to run continuously and unattended. The dryer has
sufficient capacity to effectively remove moisture for at
least 30 days. (actual time is dependent on temperature and humidity
conditions at your location. Some owners report getting up to 4
months useful life before recharging). The dryer material
contains indicator beads that change color as moisture is
absorbed. When the unit is new, the beads are blue. As moisture
is absorbed, the beads turn red. When most of the beads have
turned red, The dryer must be removed and the desiccant
recharged. This is accomplished by placing the beads in an oven
and heating them until they change back to the original color.
The Engine Saver will work with most piston
engines, including those that have an oil separator. It does not require any
installation. It does not require FAA approval.
