Why is it important for engines to have a balance of airflow and fuel?

Having a proper balance of airflow and fuel is vital for optimizing combustion efficiency in an engine. Combustion efficiency refers to how effectively the engine converts fuel into power and energy. When the airflow is balanced with the right amount of fuel, it leads to a complete combustion process, which maximizes the energy extracted from the fuel. This results in more power output for the same amount of fuel consumed, improving overall engine performance and fuel economy.

A well-tuned air-fuel mixture prevents incomplete combustion, which can lead to wasted fuel, increased emissions, and power loss. Therefore, maintaining this balance is crucial for achieving the most efficient operation in an internal combustion engine.
