What are the three major parts of a reciprocating engine induction system |
The air scoop and ducting, the carburetor, and the intake manifold |
|
|
what effect does induction system icing have on engine performance |
Induction system icing can cause an engine to act erratically and lose power |
|
|
What method is used to prevent or remove induction system icing in a reciprocating engine |
The most common method is by the use of heated air |
|
|
How is ice clear and some aircraft induction systems if the carburetor heat is too low to clear the ice |
A fluid such as alcohol, anilol, or mersol is sprayed into the induction system ahead of the carburetor. The fluid will dislodge the ice which is ingested by the engine |
|
|
What engine indication can be the results of a dirty air filter |
Low power |
|
|
What is the danger of using carburetor heat when operating at high power settings |
The higher air temperatures could cause detonation and possible engine failure |
|
|
Carburetor throttle ice is most likely to form when the throttle is in which position |
During part throttle operation when the throttle is near the closed position |
|
|
What are two general classifications of superchargers used in reciprocating engine induction systems |
They are classified as internally driven or externally driven turbocharger and supercharger systems |
|
|
What is the purpose of a distribution impeller in a supercharger |
It is designed to break up the fuel globules into finer particles for better distribution to the cylinders |
|
|
How does an internally driven supercharger boost air pressure |
A high-speed impeller is driven through a gear train from the crankshaft at a gear ratio that varies from 6:1 to 12:1 |
|
|
Where does an externally driven supercharger get its power |
The exhaust gases are directed against the turbine. For this reason, they are commonly called turbochargers |
|
|
What unit regulates the amount of exhaust gases to the turbine of a turbocharger |
The wastegate |
|
|
What type of power is used to control the position of the turbocharger wastegate on some engines |
Oil pressure to an actuatiing piston. |
