Which of the following is NOT a component of the induction system in a reciprocating engine?

In a reciprocating engine's induction system, the primary role is to ensure that a proper air-fuel mixture is delivered to the engine's cylinders for combustion. The key components of the induction system include the air scoop, carburetor or fuel control, and intake manifold.

The air scoop is responsible for directing the airflow into the induction system. The carburetor or fuel control mixes the incoming air with fuel to create the combustible mixture that is essential for engine operation. The intake manifold then distributes this mixture evenly to the engine’s cylinders.

The fuel injector, however, is not typically considered a component of the induction system in a reciprocating engine. While fuel injectors are common in aircraft equipped with fuel-injected engines, they generally fall under a different system specifically designed for delivering fuel directly into the combustion chamber rather than mixing fuel and air prior to that. Therefore, identifying the fuel injector as separate from the traditional components of a reciprocating engine's induction system is critical to understanding engine configuration and operational principles.
