BDifficulty 2/5

In a conventional electric starting system for a combustion engine, what does the starter motor do?

Correct answer

Turn the combustion engine to initiate operation.

It turns the combustion engine to initiate operation, transmitting motion through its pinion and ring gear. The starter is electric: it does not use spark or compression ignition. Its shaft speed and crankshaft speed must not be confused because transmission lies between them; there is no universal 70 rpm starter speed for every vehicle.
