What are the basic types or Inline, opposed, v-type, and radial.
configurations of reciprocating
engines?
In what position should the crankshaft The piston in cylinder no. 1 should be in the correct
be when a magneto is being timed to position for ignition to occur. This is normally about
the engine? 30° before top center on the compression stroke.
What is checked on engine runup to Idling RPM and manifold pressure, engine
determine the operational condition acceleration, maximum static RPM and manifold
of the engine? pressure, magneto drop, ignition switch safety
check, propeller pitch change, propeller feathering,
oil pressure, fuel pressure, and fuel flow.
, What is a hydraulic lock in an aircraft Oil has drained past the piston rings and filled the
engine? combustion chamber of cylinders that are below the
center line of the engine. If the crankshaft is turned
over with this oil in the cylinder it will lock, and there
is a probability that the piston, cylinder, or
connecting rod will be damaged.
How is a hydraulic lock removed from Remove a spark plug from the locked cylinder and
an aircraft engine? drain all of the oil out. Clean the spark plug and
replace it.
What are the strokes of a 4-stroke intake, compression, power, exhaust
reciprocating engine?
What are two main causes of a Piston rings not seating or broken, and valves not
cylinder having low compression? seating or burned.
What is a low-tension ignition It is an ignition system using a magneto with a
system? brush-type distributor and a coil that has no
secondary wiring. Low voltage is directed from the
magneto to a transformer mounted on the cylinder
head. Here the low voltage is boosted to a high
voltage and is directed through a very short high-
tension lead to a spark plug. There is one
transformer for each spark plug.
What are some advantages of a Low power-to-weight ratio, ideal for installation on
horizontally opposed engine? aircraft wings, and low vibration characteristics.
