The Piper Seminole is equipped with normally aspirated engines, which means that they rely on atmospheric pressure for their intake air rather than using a turbocharger or supercharger to force more air into the combustion chamber. Normally aspirated engines draw in air as the engine operates, utilizing the natural pressures created by the engine's movement and the surrounding environment. This type of engine is simpler in design and typically requires less maintenance compared to turbocharged or supercharged engines, which need additional components to manage the intake air pressure.

In the context of the Piper Seminole, the normally aspirated engines allow for straightforward operation at lower altitudes, making them well-suited for flight training and general aviation use. While variable-pitch propellers might be a feature of the Seminole's design, they relate more to the efficiency and performance of the propeller rather than the engine's operation principle. Turbocharged and supercharged engines are not applicable to the Seminole, as they would not accurately describe how its engines function.
