first the piston draws the fuel/air mixture into the engine then compress it the spark plug fires and forces it down which transforms power to the crank shaft at that point it goes up pushing the burnt fuel/air mixture out of the engine

umm...it would be sorta hard for an engine to work without a piston...unless u had a rotary engine but thats a whole nother engine...ther is 4 basic steps in a 4 stroke engine (why they call it "4" stroke, where as a "2" stroke has 2 main steps) It goes Intake stroke(fuel and air are dumped into the cylinder) next, is the compression stroke(air and fuel are compressed, a spark from the spark plug ignites the mixture) the pressure from this forces the piston downward(power/combustion stroke, this step is wat actually makes the power) then finally the exaust stroke. in this step the piston pushes the exaust gas back up through the exaust valve. these 4 strokes make the 4 stroke engine. the piston creates each of the 4 strokes.

The purpose of a piston in to receive, or exert pressure on the liquid inside the engine.

The piston transfers power thru the connecting rod to the crankshaft. This turns and is how power is transferred to whatever the motor is connected to.

It has two purposes, first to compress the fuel / air mixture and second to transmit the energy of the exploding fuel.

to compress the air and gas to make power and make u r car run.

just search "engine" on howstuffworks.com.
itll give you a ton of info, and diagrams/images/videos of them in motion.
