Which of the following components is part of a high tension magneto system?

The component that is part of a high tension magneto system is the pole shoes. In a magneto, pole shoes are critical because they are part of the magnetic circuit. The pole shoes help to concentrate and direct the magnetic flux generated by the magneto's rotating magnet, enhancing the efficiency of the ignition system. When the magnet rotates, it induces an electrical current in the coil windings, which then generates a high-voltage spark necessary for engine ignition. The design and role of pole shoes are essential for ensuring that the magneto operates effectively, delivering the required spark to ignite the fuel-air mixture in the combustion chamber.

The other components mentioned do not perform functions related to the ignition system. Fuel injectors are part of the fuel delivery system, responsible for injecting fuel into the combustion chambers. Piston rings create a seal between the piston and the cylinder wall, preventing gas leakage and maintaining compression. The crankshaft transmits power generated from combustion to the propeller or rotor, playing a crucial role in converting linear motion to rotational motion, but it does not interact with the ignition process as the pole shoes do.
