Question 175Motor Plants - Assistant Engineer70% to pass
In a diesel engine starting motor equipped with a Bendix drive, the pinion moves and meshes with the flywheel ring gear due to _______________.
AI Explanation
The correct answer is A) the shaft sleeve spiral helix and relative rotation between pinion and starter shaft.
In a diesel engine starting motor equipped with a Bendix drive, the pinion moves and meshes with the flywheel ring gear due to the spiral helix on the shaft sleeve. As the starter motor shaft rotates, the spiral helix causes the pinion to move outward, engaging with the flywheel ring gear to start the engine.
The other options are incorrect because: B) shifting levers are not involved in a Bendix drive system, C) centrifugal force does not cause the pinion engagement, and D) electromotive force is not the mechanism behind the Bendix drive operation.
