A
term referring to properties of a body in motion.
Exhaust Gas Temperature. Measurement of this gas temperature is
sometimes used as an aid to fuel management.
Opposition to the flow of exhaust gas, primarily caused by the size and
shape of the exhaust system. Atmospheric pressure also affects back
pressure.
Short for "Four Stroke Cycle." It refers to the four strokes of the
piston in completing a cycle of engine operation (Intake, Compression,
Power and Exhaust).
A
process of metering fuel into an engine by means other than
a
carburetor.
A
passageway in the engine or subcomponent.
Generally one through
which oil is flowed.
Excessive friction between two metal surfaces resulting in particles of the
softer metal being torn away and literally welded to the harder metal.
Moisture in the atmosphere.
Relative humidity, expressed in percent, is
the amount of moisture (water vapor) in the air compared with the
maximum amount of moisture the air could contain
at a given tempera-
ture.
Inability or restriction of piston rotation at
TBC due to fluid accumula-
tion in excess of combustion chamber displacement.
A mechanical device used in some magnetos to retard the ignition timing
and provide higher voltage at cranking speeds for starting.
The leanest mixture approved for any given power condition.
It is
not
necessarily the leanest mixture at which the engine will continue to
operate.
Per
FAA
AC43-11 consists of the complete disassembly of an engine,
inspected, repaired as necessary, reassembled, tested, and approved for
return to service within the fits and limits specified by the manufac-
turer's overhaul data.
This could be to new fits or limits or serviceable
limits.
The determination as to what fits and limits are used during an
engine overhaul should be clearly understood by the engine owner at the
time the engine is presented for overhaul. The owner should also be
aware of any parts that are replaced, regardless of condition, as a result
of manufacturer's overhaul data, Service Bulletin, or an
airworthiness
directive.
Pressure as measured in the intake manifold down-stream of the air
throttle. Usually measured in inches of mercury.
Mixture ratio. The proportion of fuel to air used for combustion.
