and Their Functions

Engine

The function of a car engine is to convert fuel into mechanical motion, which makes it possible for the car to move. It transforms chemical energy from the fuel into mechanical energy through an internal combustion process.

Transmission

The transmission is a device that is connected to the back of the engine and sends the power from the engine to the drive wheels.

Battery

The purpose of the battery is to supply current to the starter motor, provide current to the ignition system while cranking, to supply additional current when the demand is higher than the alternator can supply and to act as an electrical reservoir.

Car Starter

The starter motor spins the engine over so that the piston can draw in a fuel/ air mixture, which is then ignited to start the engine. When the engine starts to spin faster than the starter, a device called an overrunning clutch (bendix drive) automatically disengages the starter gear from the engine gear.

Carburetor

1.It combines gasoline and air creating a highly combustible mixture
2.It regulates the ratio of air and fuel
3.It controls the engine's speed.

Radiator

Is responsible for preventing the car engine from overheating.

Alternator

The alternator uses the principle of electromagnetism to produce current. The rotor is connected directly to the alternator pulley. The drive belt spins the pulley, which in turn spins the rotor. The stator is mounted to the body of the alternator and remains stationary.

Ignition System

1. It must control the spark and timing of the spark plug firing to match varying engine requirements
2.It must increase battery voltage to a point where it will overcome the resistance offered by the spark plug gap and fire the plug.
