My information derives from webside howstuffworks (www.

howstuffworks.com) .The explanation is supported by a diagram

in an attachment form. By turning the ignition key (1) into the

electrical circuit the system sends power from ignition module

to the battery (a storage cell)(2). A battery then sends power

to the starter (small round part attached to the engine)(3).

The engine is a heart of the entire system, and it is commonly

known as the motor(4). The starter spins the engine, so the engine

starts to turn. This causes a compression (building of power) in

 the cylinder head (a small area of the engine)(5).

 

Inside of the cylinders are a pistons (6) that start to move up and

down. At the same moment, the fuel system (7) pumps a gas from

the gas tank( a storage located outside of the engine that holds

gas)(8).The gas get mixed with the air and fuel mixture can flow

into the cylinders. On the top of a cylinder is located a spark plug

(a small part with ceramic tip that can withstand the extreme heat

and pressure inside the cylinder)(9).This plug forces the electricity

to arc across a gap and create a spark(10). The spark with air and

fuel mixture creates explosions which direct the energy in a

useful way and helps the car engine to start.
