Question 168Motor Plants - Assistant Engineer
70% to passThe pinion of an auxiliary diesel-electric starting motor normally engages the flywheel ring gear by means of a/an_______________.
Aautomatic follow-up
Bmagnetic type coupling
Cmuff coupling and release
DBendix drive or similar mechanism
AI Explanation
The correct answer is D) Bendix drive or similar mechanism. The Bendix drive is a common mechanism used to engage the pinion of an auxiliary diesel-electric starting motor with the flywheel ring gear. This mechanism allows the starting motor to crank the engine for starting, and then automatically disengages once the engine is running to prevent damage. The other answer choices are incorrect because: A) an automatic follow-up is not used for this purpose, B) a magnetic type coupling is not typically used, and C) a muff coupling and release is not the standard mechanism for this application on a diesel-electric starting system.
