Pistons
V8
Pistons are what give a car its power, its bang.
Pistons are pieces of metal that move up and down the cylinders or holes that you can see above.
They move up and down on a shaft like the one shown below.
The shaft rotates.
As the piston moves up the cylinder is filled with a mixture of fuel and air with injectors like the one shown below.
There are usually 2 injectors per cylinder.
There are usually 2 injectors per cylinder.
Then as the piston moves back down the fuel, air mixture is compressed and a small explosion happens.
These explosions can happen up to 8,000 times a minute in a road car from the combined pistons so the pistons can move very fast.
