   Odometer

This gauge, found on the dashboard of your vehicle, tells you how far it has traveled, usually measured in miles in the United States.

1. Voltage regulator
   Speedometer
2. Odometer
   Tachometer

The purpose of the voltage regulator in a vehicle is to supply a constant DC voltage, no matter what other processes are happening within the engine.

1. Gas gauge
   Tachometer
2. Speedometer
   Odometer

This gauge, found on the dashboard of your car, tells you what speed your vehicle is moving at.

1. Glow plug
   Brake shoe
2. Speedometer
   Spark plug

Glow plugs are only found in diesel engines. They form part of the starting process and heat up to ensure first time ignition.

1. Engine block
   Chassis
2. Intake manifold
   Sump

This part is essential to how your engine runs. It allows the fuel/air mixture into the cylinder of the engine where it will combust, causing the engine to run. It does this by evenly distributing the air/fuel mixture to the intake ports.

1. Distributor
   Glowplug
2. Starter motor
   Spark plug

When you turn the key of your car, the starter motor begins the combustion process by rotating the engine.

1. Water pump
   Gas pump
2. Oil filter
   Sump

This pump ensures that coolant, which is kept in the radiator, is moved through the coolant system on the car.

1. GPS system
   FM radio
2. Climate control system
   Vent selector

Climate control systems didn’t exist in years gone by, but nowadays most cars have them. Essentially, this system lets the driver adjust the ambient temperature within the cabin. It can be turned up for heat or down for cool air.

1. Engine block
   Crankshaft
2. Transmission
   Radiator

In vehicles, a transmission can be manual (where the driver selects the gears) or automatic (where the system selects the gears.) Essentially, a transmission is a range of different gears used when the vehicle is moving forward and selected to keep the engine revolutions at an optimum running speed.

1. Steering column
   Rack and pinion
2. Shock absorbers
   Driveshaft

This links the steering wheel with the other parts of the steering mechanism which are situated outside the interior of the car, nearer the front wheels.

1. Driveshaft
   Axle
2. Crankshaft
   Piston

When fuel burns in the engine, it pushes the pistons, which in turn rotate the crankshaft. This causes the vehicle to move.

A sprocket is a wheel with a set of teeth on the outer circumference. It drives items like the chain or timing belt.

1. Voltage regulator
   Ignition coil
2. Battery
