Key Terms
MISC
100
controls speed
What is the basic function of the governor
100
contains the flywieghts and spool.
What is the governor gear?
100
controls the amount of air/fuel mix that goes into the cylinder
What is the throttle plate?
100
a mechanism for regulating and controlling speed
What is a governor?
100
intake, compression, power, exhaust
What are the 4 cycles of an engine?
200
Flyweights are closed and the throttle is open
What is the position of the flyweights and throttle when engine is stopped?
200
this piece moves upward as the governor gear spins faster, moving the governor shaft
What is the spool?
200
connects the governor lever and throttle
What is the governor linkage?
200
twisting force
What is torque?
200
this part mixes air/fuel in proper proportion
What is the carburetor?
300
Air Vane, Centrifugal, Vacuum
What are the three types of common governors?
300
tension is higher on this part at high speed operation
What is the governor spring?
300
this part is moved by the governor shaft and uses the springs and linkage to open and close the throttle
What is the governor lever?
300
engine speeds up rapidly; engine responds and drops quickly; the governor stops functioning and the engine speeds up again rapidly describes this term
What is hunting?
300
these surround the cylinder and increase surface area so heat can be removed from the engine
What are the cooling fins?
400
the type of governor found on our small engines
What is a centrifugal or mechanical governor?
400
allows the operator to set desired speed
What is adjusting holes?
400
as centrifugal force increases these parts move outward
What are the flyweights?
400
ability to maintain a desired engine speed without fluctuating.
What is stability?
400
interrupt the magnetic field to create an electrical current
What is the igniton coil?
500
if a load is removed off the engine the governor will automatically prevent this
What is overspeeding?
500
connects the governor gear with the crankshaft so engine rpm can be directly proportional to governor rpm.
What is the crankshaft timing gear?
500
moved by the spool when engine rpm increases
What is the governor shaft?
500
percent of speed change requiredto produce corrective movement of the fuel control mechanism.
What is sensitivity?
500
create an air tight seal between the piston and the cylinder wall to prevent oil from getting into the combustion chamber
What are the oil rings?
