Question 476Motor Plants - Assistant Engineer

The correct answer is B) Starting motor will dangerously overspeed. If the electric starter motor pinion gear fails to disengage from the flywheel after the engine has started, the starter motor will continue to be driven by the spinning flywheel. This will cause the starter motor to dangerously overspeed, which could potentially lead to its failure or damage. The other answer choices are incorrect because: A) The engine will not stop if the starter motor pinion gear fails to disengage, as the engine is already running. C) The flywheel may not necessarily be damaged, as the starter motor will simply overspeed. D) Combustion gases will not enter the air starting system, as this scenario is specific to the starter motor and flywheel interaction.
