Which statement is true about engines equipped with fuel injection?

Engines equipped with fuel injection do not typically suffer from refrigeration icing due to their design and operation. Refrigeration icing occurs when moisture in the air freezes on engine components, which can be more prevalent in carbureted engines where fuel is mixed with air in a way that cools the mixture significantly as it moves into the engine. Fuel injection systems atomize fuel and deliver it directly into the combustion chamber or into the intake manifold, minimizing the amount of air-fuel mixing that happens outside the combustion area, thus reducing the likelihood of ice formation.

While it's true that hydraulic lock, or hydraulicing, can occur regardless of fuel system type if there is a significant issue such as fuel flooding, injectors themselves do not inherently prevent this issue. Similarly, while some systems may be more resistant to the effects of cold weather, stating that any injected engine cannot be started by swinging the propeller overlooks specific operational methods that may be employed in different engine designs. Regarding priming, while fuel injection systems often require less priming than carbureted systems thanks to their designs, they can still need some level of priming under certain circumstances, especially after long periods of inactivity.
