FUEL METERING SYSTEMS

Quiz yourself by thinking what should be in each of the black spaces below before clicking on it to display the answer.

Question
Answer
Where does the fuel metering system of a turbine engine discharge its fuel?   show
🗑
What is adjusted when the fuel control unit of a turbine engine is trimmed?   show
🗑
show At the compressor inlet and at the inlet to the diffuser section.  
🗑
show A duplex fuel nozzle is one that has two fuel discharge passages. A flow divider sends fuel for low-pressure operation through one discharge passage, and when the engine demands more fuel, it is sprayed out through the second discharge passage.  
🗑
show The float carburetor's function is to measure airflow through the engine induction system and measure out the appropriate amount of gasoline into the air for all engine operating perimeters and conditions.  
🗑
show If the mixture is not adjusted, it will become richer as the aircraft gains in altitude.  
🗑
Does the fuel-air mixture provided by a float carburetor become richer or leaner when carburetor heat is applied?   show
🗑
What would happen to the fuel-air mixture ratio in a float carburetor if the main air bleed were to become plugged?   show
🗑
show It automatically, and progressively, bleeds the air between the two sides of the air diaphragm and decreases the air metering force. This leans the mixture as the aircraft goes up in altitude.  
🗑
What are two purposes of the manifold valve (or flow divider) in the fuel injection system of a horizontally opposed aircraft engine?   show
🗑
How does the mixture control change the fuel-air mixture ratio on the Teledyne-Continental fuel injection system?   show
🗑
show Soaking the diaphragms of a pressure carburetor restores them to the condition of flexibility that they had when the carburetor was calibrated.  
🗑
show Hydropneumatic and electro-hydromechanical.  
🗑
show A stoichiometric mixture (a mixture in which all of the constituents of the fuel-air mixture are burned) produces the highest exhaust gas temperature.  
🗑
show The throttle stop, to get the proper idling RPM, and the idle mixture control, to get the smoothest operation.  
🗑
show The high unmetered fuel pressure.  
🗑
show These letters designate the relative size of the orifice in the injector nozzle. The lower the letter in the alphabet, the smaller the amount of fuel the nozzle will flow.  
🗑
What is the function of the derichment valve in a pressure carburetor used on an aircraft engine with an antidetonation injection system?   show
🗑
show The economizer (or power enrichment) system allows the engine to operate with an economically lean mixture for all conditions other than full power.  
🗑
show In the Idle Cutoff position. The engine is started with fuel from the primer system.  
🗑
In what position is the carburetor heat control placed when starting an aircraft engine?   show
🗑
show By shutting off the fuel to the cylinders, the combustion chambers are left full of air with no fuel. This makes the engine less likely to fire if the propeller is pulled through with the ignition switch accidentally on.  
🗑
show It is discharged through injector nozzles screwed into the cylinder heads near the intake valves.  
🗑
show If the wind velocity is less than 10 miles per hour, it can be faced in any direction. If the wind velocity is between 10 and 25 MPH, it should be trimmed facing into the wind. The engine should not be trimmed when the wind velocity is more than 25 MPH.  
🗑
show Engine RPM, inlet air pressure, compressor discharge pressure, burner can pressure, and inlet air temperature.  
🗑
When does the acceleration system operate on an aircraft carburetor?   show
🗑


   

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
