Induction Systems Flashcards
How does induction icing affect engine performance
Reduced power and possible erratic operation
How is induction icing categorized
Impact, fuel evaporation , and throttle ice
What causes fuel evaporation ice
A decrease in air temperature
What is the common method used to prevent induction system ice in reciprocating engine
Raise the temperature of induction air
What may be the indication of leaking intake pipes
Engine runs rough at low r.p.m
What happens if carburetor heat is applied at high engine power settings
Detonation.
Is carburetor throttle ice more likely to occur at a higher or lower power setting? Why?
At a lower power setting because the throttle is partly closed, offering a larger surface area for ice accumulation
What could happen if the induction system becomes obstructed
Engine may not produce it’s rated power or it may not run at all. This may also mean that there is a dirty air inlet filter
What are two types of supercharged induction systems
Internally driven and externally driven
What is used to power a turbocharger
Engine exhaust gas directed onto the turbocharger turbine
What function does a turbocharger wast gate perform
Controls the amount of exhaust gas into or around the turbocharger
What could cause a turbocharged engine to surge
Wast gate or controller malfunction
Where are bellmouth inlet ducts typically found
On helicopter engines
What are the most common methods used for anti icing of turbine engine inlet ducts
Engine bleed air and electric heated elements
In a pressurized reciprocating aircraft what component in the turbocharger system is used to limit the amount of turbocharger airflow used for cabin pressurization
Sonic Venturi
