2
Q
- What effect does induction system icing have on engine performance?
A
Act erratically
Lose power
Possibly quit
3
Q
- What method is used to prevent or remove induction system ice in a reciprocating engine?
A
Heated air
4
Q
- How is ice cleared in some aircraft induction systems if the carburetor heat is too low to clear the ice?
A
Alcohol sprayed into induction system
5
Q
- What engine indication can be the result of a dirty air filter?
A
Low power
6
Q
- What is the danger of using carburetor heat when operatin at high power settings?
A
High air temps could cause detonation
7

A
Break up fuel globules
10
Q
- How does an internally driven supercharger get its power?
A
Mechanically driven
11
Q
- Where does an externally driven supercharger get its power?
A
Exhaust gases directed against turbine
12
Q
- What unit regulates the amount of exhaust gases to the turbine of a turbocharger?
A
Waste gate
13
Q
- What type of power is used to control the position of the turbocharger waste gate on some engines?
A
Oil pressure to an actuating piston
14
Q
- What can cause the waste gate to stick?
A
Buildup of carbon
