Engine Components Flashcards
What houses the crank shaft and cam shafts
Crankcase
What is the cankcase usally made of
Aluminium alloy
How is the crankcase usually made
Forged or casted
What usually carries the engine mounts for fitment to the airframe
The crankcase
What component converts combustion energy to mechanical energy
The pistons
Why do the pistons convert combustion energy to mechanical energy
To drive the crankshaft
What provides a gas tight seal between the piston and the cylinder
The piston (compression) ring
What are the rings fitted below the compression piston ring used for
Oil control.
Scrape lubricant (oil) from cylinder walls to prevent entering the combusion chamber.
Why would blue or black smoke be coming out of your exhaust
Burning oil.
If oil has leaked into the combustion chamber and you are burning oil.
If oil has leaked into the combustion chamber what does this mean for your oil consumption.
It will increase.
Meaning you might need more oil depending on severity of leak. 
What does the cylinder house
The pistons.
Privides the (cylinder) bore in which the piston moves
What acts as the compression and expansion chambers
The cylinders
What do the cylinders act as
the compression and expansion chambers
What does the cylinder head seal
The top of the cylinder from the combustion chamber
What seals the top of the cylinder from the combustion chamber
The cylinder head
What does the cranshaft convert
The reciprocating motion of the pistons to rotary motion
Why does the crankshaft convert the reciprocating motion of the pistons to rotary motion
To drive the propeller
What converts the reciprocating motion of the pistons to rotary motion
The crankshaft
What connects the pistons to the crankshaft
The connecting rods
What do the connecting rods connect
The pistons to the crankshaft
What dives the cam shaft
The crankshaft
What is the speed of the cam shafts
Half the speed of the crankshaft
What does the cam shaft control
The opening and closing of the inlet and exhaust valves.
Valve timing
What controls the opening and closing of the inlet and exhaust valves.
The camshaft
Valve timing
What assembly opens each valve
The push rod and rocker assembly.
Involves the valve springs
How are the valves closed
By the valve springs.
Timed by the cam shaft. When it roates off its lobe. The springs stretch back which closes the valve.
Can u have double valve springs
Yes.
Are oftern used to provide more rapid and positive valve closing as well as eliminating valve bounce.
