Question 1 of 27070

Which of the listed devices is often used in combination with the flywheel of small and medium size diesel engines for the purpose of starting?

🔍 Key Concepts

• Think about how small and medium diesel engines are commonly started on vessels without using a large electric starter motor directly on the flywheel. • Consider which device from the list is designed to engage with a flywheel ring gear to spin the engine for starting. • Recall that some options listed are used for ignition or power generation, not for physically cranking the engine.

💭 Think About

• Which of the choices is a mechanical or pneumatic device whose job is to turn the flywheel, rather than produce electricity or control electronics? • Ask yourself: on a typical small marine diesel, what actually meshes with the flywheel teeth to crank the engine? • Eliminate any option that is mainly for making sparks, controlling current, or generating electricity, rather than for cranking the engine.

✅ Before You Answer

• Verify which device is specifically designed to mesh with a gear (often the flywheel ring gear) to transmit torque for starting. • Check your basic engine systems: which item is commonly part of a starting motor assembly, not part of the charging or ignition system? • Be sure the device you pick has a function related to cranking/starting the engine, not supplying power or controlling voltage.
