What is the primary function of an intercooler in a turbocharged engine?

• A. To increase fuel efficiency
• B. To cool compressed air before combustion
• C. To enhance airflow into the engine
• D. To elevate exhaust velocity

Answer: (B)

The primary function of an intercooler in a turbocharged engine is to cool the compressed air before it enters the combustion chamber. When air is compressed by the turbocharger, its temperature rises significantly due to the energy added during compression. This high temperature can lead to several issues, including knocking and a reduction in engine performance and efficiency. The intercooler works by passing the hot, compressed air through a heat exchanger where it is cooled down, often using ambient air or coolant. Lowering the intake air temperature increases its density, which allows for more air to enter the combustion chamber. This results in a more efficient combustion process, leading to improved engine performance, increased power output, and better fuel efficiency during operation. In summary, the intercooler is essential for maintaining optimal intake temperatures, enhancing the overall functionality of a turbocharged engine.
