Which of the following factors can lead to reduced engine power in an induction system?

Reduced engine power in an induction system can occur due to induction system obstruction. The induction system is responsible for delivering air (and fuel) to the engine for combustion. When there is an obstruction, whether from debris, ice, or other blockages, the airflow to the engine is restricted. This results in less air entering the combustion chamber, leading to a lean mixture of fuel to air, which diminishes overall engine performance and power output.

Understanding the impact of induction system health is crucial for aircraft performance; obstructions can be significant contributors to power loss, highlighting the need for regular maintenance and inspection of the system to ensure unobstructed airflow for optimal engine operation.
