How do turbochargers increase engine power?

• A. By reducing the weight of the engine
• B. By forcing more air into the combustion chamber
• C. By using less fuel
• D. By improving exhaust flow

Answer: (B)

Turbochargers enhance engine power by forcing more air into the combustion chamber. This process is critical because an engine's power output is related to the amount of air and fuel it can combust. The turbocharger uses exhaust gases from the engine to spin a turbine, which, in turn, drives a compressor that draws in more air. This increase in airflow allows for more fuel to be added to the combustion process, resulting in a more powerful explosion in the cylinders.

In essence, with a turbocharger, the engine can generate more power without increasing its size. This is beneficial for improving efficiency and power without necessitating a larger engine or additional displacement. By maximizing the air intake, turbochargers enable the engine to burn more fuel, leading to a significant boost in overall performance.
