Induction Icing: A Phenomenon That Impairs the Engine’s Performance
Induction icing is a type of ice that develops within the engine’s induction system and affects the amount of air available for combustion, thus impairing the engine’s performance. This phenomenon is commonly found in carburetor systems, where moisture in the air freezes and accumulates on the surface of the throttle valve and other components, ultimately obstructing the flow of air to the engine. Induction icing occurs when the temperature and humidity conditions allow the moisture in the air to freeze, forming ice crystals that can adhere to the system’s surfaces. This can reduce the efficiency of air induction, decrease engine power, increase fuel consumption, and even cause a complete engine failure. Pilots must be aware of this phenomenon and take necessary precautions such as using carburetor heat, adjusting the fuel mixture, and observing weather conditions to prevent induction icing from occurring. Proper maintenance and regular inspections of the induction system, including carburetors and air filters, can also help reduce the risk of induction icing and ensure the safety of the aircraft.
