Al-Jazari,a Kurdish engineer, invented the conversion of the up and down piston movement in a cylinder into rotary motion.
A stroke.
The up and down movement of a piston is called reciprocating motion. This motion is essential in internal combustion engines where the reciprocating motion of the pistons converts the pressure created by burning fuel into rotational motion to drive the vehicle.
The piston has the same function whether diesel or petrol. The piston is forced down the cylinder when the petrol mixture ignites and expands. That in turn presses on the connecting rod which in turn pushes on the crankshaft. The crankshaft changes the up and down movement of the piston into a rotational movement which makes the car go.
Each up or down movement of a piston in an internal combustion engine is called a stroke. The four strokes in a typical engine cycle are intake, compression, power (or combustion), and exhaust.
the piston would push air down and fluid up.
A piston is located in the Center of the engine, it mixes fuel and ignites it by moving up and down. this up and down movement is caused by the crankshaft which spins really fast with groves were the pistons shafts connect. the piston head is the piece that effects the fuel ignition.
As the piston moves up and down in the cylinder it also moves the piston rings up and down in the grooves. With the rings moving up and down it gradually increases the side clearence. Material is taken off from both the piston groove and the ring.
Depends on the length of stroke of the piston. A piston goes up and down once per rev. so do the the calculation how many time the piston travels up and down in a min then work it against the distance travelled.
In essence, the the displacement of the piston is porportional to the sine of the phase of the crankshaft. this isn't quite true but it gives a rough idea of what is happening. if you meant what happens in one cycle of a piston/crankshaft then it is essentially this: as the piston moves down it forces the crankshaft through one half of a revolution and then on the way back up the piston forces the crankshaft through the remaining half of a revolution - back to its start position to start again
The piston moves up and down inside the engine cylinder.
Piston rings are always installed with the numbers up toward the top of the piston
