16 cards
Card 1
Question: What is the function of blast tubes installed in a pressure cooling system of a reciprocating engine?
Answer: To direct cooling air to the magnetos and the generator.
Card 2
Question: Where is the heat taken from that is used to heat the induction air in a reciprocating engine?
Answer: From a shroud installed around some part of the exhaust system (from inside the engine cowling).
Card 3
Question: Where does carburetor ice normally form?
Answer: In the throat of the carburetor, on and around the throttle valve.
Card 4
Question: Does applying carburetor heat make the air‑fuel mixture richer or leaner?
Answer: Heated air causes the air‑fuel mixture to become richer.
Card 5
Question: What happens to engine RPM when carburetor heat is applied?
Answer: Engine RPM drops.
Card 6
Question: How is a supercharger driven?
Answer: The supercharger is directly driven from the engine and is internal to the engine.
Card 7
Question: What controls the speed of a turbocharger compressor?
Answer: The amount of exhaust gas forced through the turbine, controlled by the position of the wastegate.
Card 8
Question: What is the danger of operating a reciprocating engine with too high a carburetor air temperature?
Answer: The air‑fuel mixture can reach its critical temperature and detonate.
Card 9
Question: What is usually installed in a large reciprocating engine between the turbosupercharger and the carburetor?
Answer: An intercooler (an air‑to‑air heat exchanger).
Card 10
Question: In what position should the carburetor heat control be placed when starting a reciprocating engine?
Answer: In the COLD position.
