a far from my knowledge one piston stroke is the distance the piston head traveled from bottom end of cylinder to top end of the cylinder
For engines, volume measured from top of cylinder to top of piston when at bottom of its stroke.

Stroke volume is used to measure the heart rate and arterial pressure. Most people who have had a heart attack or stroke or are at risk of having either of these issues must have their heart tested using stroke volume.
It is called an Internal Combustion Engine(ICE for short) and covers a broad range of engine types not just the specified piston-cylinder engines asked about, but covers any kind of power source where fuel is burned with air(oxidised), inside a confined space and the resulting energy is used to turn a shaft through pistons and levers or turbines so that the energy can be used for a desired purposed. There are many different types of piston-cylinder engines but the most common ones in cars are four stroke petrol or diesel engines, less common are two stroke petrol and diesel engines. There are other types but of no real note to anyone except engineers and related disciplines.
Neither a four stroke nor a two stroke have a bigger piston. It all depends on the size of the engine and how it is built. A 250 four stroke will have the same sized piston that a 250 two stroke would if the bore size is the same. Cc is calculated by bore x stroke (how far up and down the piston moves) so if a 250 four stroke has a stroke of 3.00 inches and a 250 2 stroke has a stroke of 3.00 the piston will be the same size. The only difference between a 2 stroke and four stroke is how the engine works. A 2 stroke has reed valves and it makes power every time the piston goes up but a four stroke it makes power every 4 times the piston goes up.
bore is the diameter of the piston and stroke is the length the piston moves in the cylinder.for example if bore x stroke is 1x3 then 1 is the diameter of the piston and 3 is the length of the cylinder.if bore is greater than stroke then it is a short stroke engine.
In a 2 stroke engine the piston itself is the intake/exhaust valve, instead of having separate valves as in the 4 stroke. The odd shape of the piston is the location of these valves.
The difference is in the amount of stokes the piston makes in one cycle. A four stroke will explode on one stroke turning the engine over. Then on the up stroke it pushes the exhaust out. The next down stroke fills the cylinder with fuel. On the final stroke the piston compresses the fuel and the cycle repeats. This results in four strokes of the piston. A two stroke has two strokes of the piston before it repeats the cycle. The first stroke is the explosion. The piston is pushed down. on the down stroke the piston reveals a port that exhausts, and then another port is revealed that fills the cylinder with fuel. the up stroke compresses the fuel and then the cycle repeats. The logical difference is the 2 stroke will accelerate faster
Both con-rod length and shape of the crankshaft affect piston stroke
A stroke is the movement of a piston up or down.
Its the distance from piston back, to piston out
The distance a piston travels within the cylinder is called the stroke. It is the distance between the top dead center (TDC) and the bottom dead center (BDC) positions of the piston.
The speed of a piston in an engine is determined by the engine's RPM (revolutions per minute) and the stroke length of the piston. The speed can be calculated using the formula: speed = (2 * pi * RPM * stroke length) / 60. Increasing the RPM or stroke length will increase the speed of the piston.
As the name states there are 4 strokes in a 4 stroke engine. Intake, when the piston draws in air/Fuel mixture. Compression, when the intake valve closes and the piston moves to the top off the stroke. Power stroke, when the compressed mixture is ignited, forcing the piston down. Last the exhaust stroke when the piston starts moving up and expells the burnt gases.
All gasoline engines are four-stroke designs. An engine has an intake stroke where the intake valve is open and the piston is moving downward, creating a vacuum that sucks the fuel into the cylinder. The next stroke is the compression stroke. The intake valve closes, and the piston begins to move upward and compresses the fuel in preparation for ignition. The third stroke is the power stroke. The piston is approaches the top of the cylinder in the compression stroke. Just before it gets to top dead center, the spark plug fires and ignites the fuel. The fuel rapidly expands and pushes the piston down with great force. The last stroke is the exhaust stroke. In this stroke, the piston completes the power stroke and begins to rise again. At this point the exhaust valve opens, and the piston forces the exhaust out of the cylinder in preparation for the intake stroke.
Bore is the diameter of the piston/cylinder, stroke is the distance the piston can travel between its highest position and its lowest position in the cylinder.
