Induction system ice types include which of the following?

• A. Impact ice, fuel evaporation ice, and throttle ice
• B. Impact ice, throttle ice, and intake ice
• C. Fuel evaporation ice and frost ice
• D. Carb ice, exhaust ice, and wing ice

Answer: (A)

Induction system icing can form in a few different ways as air moves through the intake and throttle area. The three main kinds you’ll see are impact ice, fuel evaporation icing, and throttle icing. Impact ice happens when supercooled droplets strike the intake surfaces and freeze, narrowing the airflow path. Fuel evaporation icing occurs when fuel vaporizes and cools the air in the intake, which can cause ice to form inside the induction tract in humid, near-freezing conditions. Throttle icing develops around the throttle valve due to cooling from the rapid expansion and restriction of the air, freezing on the throttle body surfaces. Other terms like frost ice, wing ice, or exhaust ice describe icing on surfaces outside the induction path, and carb ice is specific to carbureted systems rather than the general induction-ice types. So the three induction-ice types are impact ice, fuel evaporation icing, and throttle icing.
