air-fuel mixture

The **air-fuel mixture** refers to the precise blend of air and fuel that is combined and delivered into the engine’s combustion chamber. This mixture plays a crucial role in the efficiency, performance, and emissions of internal combustion engines. An optimal air-fuel ratio ensures complete combustion, maximizing power output while minimizing harmful pollutants. Understanding and controlling the air-fuel mixture is essential for mechanics, automotive enthusiasts, and engineers looking to improve engine function and fuel economy.
