    Nov 18, 2020 · How Our Air to Fuel Ratio Control Works. The air intake opens and closes, controlling the amount of air in the firebox to ensure the fuel burns efficiently at every stage of the cycle. If there is too little oxygen in the lower chamber, the upper air will flood the combustion, just like flooding an engine. By adding the precise amount of oxygen required the air to fuel ratio control allows for the cleanest and …Learn More
