What is the function of an augmenter system in an exhaust system?

To increase engine power
To reduce engine weight
To draw additional air over the engine for cooling
To enhance fuel injection

The correct answer is: To draw additional air over the engine for cooling

The function of an augmenter system in an exhaust system is primarily to draw additional air over the engine for cooling. This system is designed to enhance the airflow around the engine, which helps maintain optimal operating temperatures and can improve overall engine performance. By utilizing the exhaust gases' energy, the augmenter creates a low-pressure area that facilitates the intake of ambient air, aiding in both cooling and combustion efficiency. This process can be particularly important in high-performance and turbocharged engines, where effective heat management is crucial for sustaining power and reliability.
