Carbs
Which method is commonly used to adjust the level of a float in a float-type carburetor?
Add or remove shims under the needle-valve seat.
When trimming a turbine engine, the fuel control is adjusted to
set idle RPM and maximum speed or EPR.
The primary purpose of baffles and deflectors installed around cylinders of air-cooled engines is to
force cooling air into close contact with all parts of the cylinders
Float-type carburetors, which are equipped with economizers, are normally set for
their leanest practical mixture delivery at cruising speeds and enriched by means of the economizer system at higher power settings.
What is Mr. Doyles First Name.
Kacy
If the main air bleed of a float-type carburetor becomes clogged, the engine will run_________
rich at rated power.
In order to stabilize cams, springs, and linkages within the fuel control, manufacturers generally recommend that all final turbine engine trim adjustments be made in the
increase direction
Prolonged idling of an engine will usually result in
foreign material buildup on spark plugs
. Fuel is discharged for idling speeds on a float-type carburetor
from the idle discharge nozzle.
How do mechanics make pilots stay humble?
They Ground them
On a float-type carburetor, the purpose of the economizer valve is to?
provide a richer mixture and cooling at maximum power output
Which of the following is NOT a factor in the operation of an automatic fuel control uning used on turbine engines?
Throttle position.
Mixture control position.
Compressor inlet air density.
B. Mixture control position.
The primary purpose of baffles and deflectors installed around cylinders of air-cooled engines is to
force cooling air into close contact with all parts of the cylinders
The primary purpose of an air bleed in a float-type carburetor is to?
decrease fuel density and destroy surface tension
What do you call a factory that makes okay products?
A satisfactory
If an aircraft engine is equipped with a carburetor that is not compensated for altitude and temperature variations, the fuel/air mixture will become
richer as either the altitude or temperature increases
In a supervisory EEC system, any fault in the EEC that adversely affects engine operation?
causes an immediate reversion to control by the hydro mechanical fuel control unit.
Which of the following should a mechanic consult to determine the maximum amount of cylinder cooling fin that could be removed when cracks are found?
Engine manufacturer’s service or overhaul manual
Why must a float-type carburetor supply a rich mixture during idle?
Because at idling speeds the engine may not have enough airflow around they cylinders to provide proper cooling.
Why are nurses always running out of red crayons?
Because they often have to draw blood!
What carburetor component measures the amount of air delivered to the engine?
Venturi.
A supervisory electronic engine control (EEC) is a system that receives engine operating information and
adjusts a standard hydro mechanical fuel control unit to obtain the most effective engine operation.
. During ground operation of an engine, the cowl flaps should be in what position?
Fully open
The device that controls the ratio of the fuel/air mixture to the cylinders is called a
mixture control.
What’s the difference between a hippo and a Zippo?
One is very heavy, the other is a little lighter!
