Ignition and engine airflow systems

Question 1

What are the three major parts of a reciprocating engine induction system

Answer 1

The air scoop, fuel delivery system and intake manifold

Question 2

What effect does the induction system icing have on engine performance

Answer 2

Icing can cause an engine to act erratically and lose power, and may possibly quit

Question 3

What method is used to prevent or remove induction system ice in a reciprocating engine

Answer 3

Do use of heated air

Question 4

How is ice cleared in some aircraft induction systems if the carburetor heat is too low to clean the ice

Answer 4

Alcohol, anilol, or mersol Is sprayed into the induction system ahead of the carburetor.

The flu it will dislodge the ice which is ingested by the engine

Question 5

What engine indication can be the result of dirty air filter

Answer 5

Low power

Question 6

What is the danger of using carburetor heat when operating at high power settings

Answer 6

The higher air temperatures could cause detonation and possible engine failure

Question 7

Carburetor throttle ice is most likely to form when the throttle is in which position

Answer 7

Partly closed position

Question 8

What are two general classifications of superchargers used in reciprocating engine induction systems

Answer 8

Internally driven, or externally driven

Question 9

What is the purpose of a distribution propeller in a radial engine

Answer 9

Designed to break up the fuel Globules Into finer particles for better distribution to the cylinders

Question 10

How does an internallyDriven supercharger get its power

Answer 10

They are mechanically engine driven

A high speed impeller is driven through a gear train from the crankshaft. The use of gear ratios can be single stage or two speed. A two speedGear ratio normally varies from 6:1 to 12:1

Question 11

Where does an external he driven supercharger get its power

Answer 11

Exhaust gases that are directly adjust a turbine. For this reason they are commonly called turbo chargers

Question 12

What unit regulates the amount of exhaust gases to a turban of a turbo charger

Answer 12

The wastegate

Question 13

What type of power is used to control the position of the turbo charger wastegate on some engines

Answer 13

Oil pressure to an actuating piston

Question 14

What can cause the wastegate to stick

Answer 14

Build up of carbon can cause the wastegate stick
