Carboretta Flashcards
How is fuel able to become charge?
Low pressure due to venturi tube.
In the climb, with no adjustment, the mixture becomes more blank.
Rich.
What can you use to control fuel flow within a carboretta?
Jets.
What vaporises fuel in a carboretta?
Atomiser.
The diffuser is also known as the blank tube within the carboretta?
Emulsification.
What two reasons make us use rich mixture on takeoff?
Power and cooling.
What does the accelerator pump prevent in a carboretta?
Lean cut.
How many pumps of the throttle do you have to do when starting in a piston aircraft with a carboretta?
3.
How much loss in power can carboretta heat cause?
15%.
What is a risk of using carboretta heat?
Increased detonation.
Why does icing occur in a carboretta?
Decrease in pressure and therefore temperature.
If the manifold pressure gauge of a piston engine shows an increase shortly after carburettor heat is turned on, what occurs?
Ice is forming on the carborretta.
The use of carburettor heating during take-off and climb is discouraged because of the loss of blank and increased risk of blank.
Power and detonation.
The first indication of carburettor icing on an aeroplane with a piston engine and a constant speed propeller during cruise is a increase/decrease in manifold pressure.
Decrease.
