Internal combustion engine
The car is started using a powerful electric motor, called a starter motor. The car is started using a key which is connected to the starter solenoid (a device that converts electrical energy into mechanical energy or movement) and when the key is turned into the start position, the ignition switch verifies the key belongs to the car normally using an immobilizer system and then connects a circuit, sending power to the starter relay. It then sends 2 jolts of electricity into the solenoid, the larger burst being directly from the battery pack in the car and the other being from the ignition. The magnetic field created from the solenoid connects two metal (metal being a conductor to electricity) contact points, one being the solenoid plunger, together which then relays the electricity into the starter motor. The plunger also engages a fork which pushes the pinion gear (connected to the starter motor) to engage the flywheel automatically, starting the engine.
