acts as a supplemental source of energy to moderate engine performance |
|
delivers current to the ignition system to start the engine |
|
delivers supplemental current when the alternator can't handle high electrical system loads |
The lead-acid battery is the core of the electrical system, providing current to the ignition system to start the engine as well as delivering supplemental current when the alternator can't handle high electrical system loads and acting as an electrical reservoir for excessive current.
__________ are made with wide gap coils of rigid steel cable and both hold the vehicle chassis up off the ground and absorb energy from wheel movement making for a smoother ride.
suspension springs |
|
control arms |
|
shock absorbers |
|
ignition coils |

What is the function of the alternator?
provides AC power for the car's electrical components |
|
replaces the electrical energy that the car draws from the battery |
|
charges the battery when the car is not running |
|
converts motion from the wheels into DC power |
An automobile's electrical system runs on DC power and the bulk of that power is supplied by the battery. The alternator converts the motion of the rotor into AC power which is then fed through the rectifier to convert it to DC power that both the car and the battery can use.
The wheel __________ is the mounting point for the wheel and tire assembly.
base |
|
shaft |
|
hub |
|
knuckle |
The wheel hub is the mounting point for the wheel and tire assembly. The wheel hub can rotate while being held stable by the steering knuckle which applies the motion of the control arms to the wheels.
