Working of a Car

                      

When a driver turns a key in the ignition:

      The car battery powers up sending

      Power to the starter motor, which

      Turns the crankshaft, which

      Gets the pistons moving

      With the pistons moving the engine fires up and ticks over

      A fan draws air into the engine via an air filter

      The air filter removes dirt and grit from the air

      The cleaned air is drawn into a chamber where fuel (petrol or diesel) is added

      This fuel-air mix (a vaporised gas) is stored in the chamber

      The driver presses the accelerator pedal

      The throttle valve is opened

      The gas-air mix passes through an intake manifold and is distributed, through intake valves, into the cylinders. The camshaft controls the opening and closing of the valves.

      The distributor makes the spark plugs spark, which ignites the fuel-air mix. The resulting explosion forces a piston to move down which in turn causes the crankshaft to rotate.
