Pp Flashcards
It has a ground face that form a seal against the ground valve seat in the cylinder head when the valve is closed.
Valve Head
It is a resistant to high temperature corrosion and also withstands the shock and wear associated with valve operation.
Stellite
It joins the piston to the connecting rod. -
Piston Pin
The piston pin is sometimes called?
Wrist Pin
The portion of the engine in which the power is developed in called what?
Cylinder
The portion of the piston walls that lie between the ring grooves are called what?
Ring Lands
The majority of aircraft engine pistons are machined from what?
Aluminum alloy Forgings
It is a cylindrical member which moves back and forth within a steel cylinder of a reciprocating engine.
Piston
It is the backbone of the reciprocating engine
Crankshaft
- It is a solid construction except for the oil passage drilled in the pins which lubricate the knuckle pin bushings.
Knuckle Pins
The link that transmit forces between the piston and the crankshaft.
Connecting Rod
It contains an insulated wire for each cylinder that the magneto serves in the engine.
Ignition Harness
It is mounted on the engine so that air to the cylinders passes through the barrel, the part of the carburetor which contains the venturi.
Carburetor
It generates electrical power by the engine rotating the permanent magnet and inducing a current to flow in the coil windings.
Magneto
It is the foundation of an engine.
Crankcase
It is a special type of engine driver alternating current (AC) generator, uses a permanent magnet as a source of energy.
Magneto
It is a good conductor of heat and its light weight reduces the overall engine weight.
Aluminum Alloy
Exhaust valves are usually made of nichrome or cobalt chromium steel because these materials are much more what?
Heat Resistant
It is merely a pendulum that is fastened to the crankshaft so that it is free to move in a small arc.
Dynamic Damper
The various gear ratios arranged improper drive speed to magnetos.
False
The webs form an integral part of the structure supporting main bearings add the strength entire case.
True
Gear trains, containing both spur- and bevel-type gears, are used in the different types of engines.
True
The function of sparkplug in ignition system is to conduct short impulse of high voltage current.
True
The connecting rod main bearings must be supported rigidly in the crankcase.
False (Crankshaft main bearings)
The crankshaft as the name implies is a shaft compose of 2 or more cranks located at specified parts along its length.
True
The crankshaft is divided into 2 sections in a longitudinal plane.
False- Crankcase
The main purpose of crankshaft is to transform reciprocating motion.
True
