Q

The pinion of an auxiliary diesel-electric starting motor normally engages the flywheel ring gear by means of a/an __________.

🔍 Key Concepts

• Auxiliary diesel-electric starting motor function and components • How a small electric motor engages a larger engine's flywheel ring gear • Common starter engagement mechanisms such as a Bendix drive

💭 Think About

• Which device allows a small pinion gear to automatically move into and out of mesh with the flywheel gear as speed changes? • Which choice sounds like a mechanical, speed‑sensitive engagement device used on many small and medium diesel engine starters? • Which options clearly are NOT typical means of engaging a starter pinion to a flywheel (think about what a coupling or follow-up system usually does)?

✅ Before You Answer

• Identify which option specifically refers to a starter drive mechanism rather than a general coupling or control system. • Consider which device uses axial movement of a pinion along a helical shaft to mesh with the ring gear when the starter spins. • Eliminate any options that are mainly used for power transmission between shafts rather than for temporary gear engagement.
