HowStuffWorks "How Alternators Work" How the starting system works | How a Car Works. To make an engine start it must be turned at some speed, so that it sucks fuel and air into the cylinders, and compresses it. The powerful electric starter motor does the turning. Its shaft carries a small pinion (gear wheel) which engages with a large gear ring around the rim of the engine flywheel. In a front-engine layout, the starter is mounted low down near the back of the engine. The starter needs a heavy electric current, which it draws through thick wires from the battery. No ordinary hand-operated switch could switch it on: it needs a large switch to handle the high current. The switch has to be turned on and off very quickly to avoid dangerous, damaging sparking.
The starter switch is usually worked by the ignition key. The ignition switch has a return spring, so that as soon as you release the key it springs back and turns the starter switch off. When the switch feeds current to the solenoid, the electromagnet attracts an iron rod. Simple alternator description. Alternative current. Battery stater motor alternator. Car electrics.
