What influence does the turbocharger have on fuel efficiency?

The turbocharger significantly enhances fuel efficiency by improving air intake into the engine. It accomplishes this by utilizing the exhaust gases that would typically be wasted, converting them into additional air pressure that forces more air into the combustion chamber. This increased airflow allows for a more complete and efficient combustion process, which means that the engine can produce more power using the same amount of fuel. As a result, vehicles equipped with turbocharged engines often experience better fuel economy, especially under varying load conditions. This is crucial for maximizing performance while minimizing fuel usage, making turbochargers beneficial for both efficiency and power output.
