The distance from Top Dead Center to Bottom Dead Center of piston movement.
The distance from Top Dead Center to Bottom Dead Center of piston movement.
In a hydraulic jack, a stroke refers to the distance the piston can move vertically within the cylinder of the jack. This distance ultimately determines the maximum height that the jack can lift an object. To calculate the stroke length, measure from the fully collapsed position to the fully extended position of the piston.
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
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
Its the distance from piston back, to piston out
A stroke is the movement of a piston up or down.
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.
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.
