Ever wonder what the heck makes your quad move from point A to point B? This is how...
First off its called a "four stroke" motor because it goes through four "strokes" to produce its power. The four strokes are...
1) Intake stroke
2) Compression stroke
3) Combustion stroke
4) Exhaust stroke
The steps are...
1) The piston starts at the top, the intake valve opens, and the piston moves down to let the engine take in a cylinder-full of air and gasoline. This is the intake stroke. Only the tiniest drop of gasoline needs to be mixed into the air for this to work.
2) Then the piston moves back up to compress this fuel/air mixture. Compression makes the explosion more powerful.
3) When the piston reaches the top of its stroke, the spark plug emits a spark to ignite the gasoline. The gasoline charge in the cylinder explodes, driving the piston down.
4) Once the piston hits the bottom of its stroke, the exhaust valve opens and the exhaust leaves the cylinder to go out the tail pipe.
Now the engine is ready for the next cycle, so it intakes another charge of air and gas.
And that my friends, is how a 4stroke engine works :D
