What are the three major parts of a reciprocating engine induction system? |
Air scoop, fuel delivery system and intake manifold. |
|
|
What effect does induction system icing have on engine performance? |
Cause an engine to act erratically and lose power and may possibly quit. |
|
|
What method is used to prevent or remove induction system ice in a reciprocating engine? |
Heated air |
|
|
How is ice cleared in some aircraft induction systems, if the carburetor heat is too low to clear the ice? |
Alcohol, Anilol or Mersol is sprayed into the induction system ahead of the carburetor. |
|
|
What engine indication can be the result of a dirty air filter? |
Low power |
|
|
What is the danger of using carburetor heat when operating at high power settings? |
Detonation and possible engine failure. |
|
|
Carburetor throttle ice is most likely to form when the throttle is in which position? |
Partially closed position |
|
|
What are two general classifications of superchargers used in reciprocating engine induction systems? |
Internally driven or externally driven (tubrocharger) supercharger systems |
|
|
What is the purpose of a distribution impeller in a radial engine? |
It is designed to break up the fuel globules into finer particles for better distribution to the cylinders |
|
|
How does an internally driven supercharger get its power? |
A high speed impeller is driven through a gear train from the crankshaft. The use of gear ratios they can be single stage or two speed. |
|
|
Where does an externally driven supercharger get its power |
Exhaust gases are directed against a turbine. |
|
|
What unit regulates the amount of exhaust gases to the turbine of a turbocharger? |
Waste gate |
|
|
What type of power is used to control the position of the turbocharger waste gate on some engines? |
Oil pressure to an actuating piston. |
|
|
What can cause a waste gate to stick? |
A build up of carbon can cause the waste gate to stick. |
