It involves the downward movement of the piston, creating a partial vacuum that draws an air-fuel mixture (or air alone, in the case of a direct injection engine) into the combustion chamber. The mixture enters the cylinder through an intake valve at the top of the cylinder.
Zero degrees occurs when the piston is at the top of the cylinder. Since there are 360 degrees in one revolution, the piston is at the bottom when the crank angle is 180 degrees. The distance traveled by the piston from zero degrees to 180 degrees is called the stroke - S of the piston.
In a four-stroke engine, each cylinder "fires" on every second revolution of the crankshaft. The full combustion cycle consists of two revolutions of the crankshaft and four strokes: 1. Intake stroke 2. Compression stroke 3. Power stroke 4. Exhaust stroke.
An engine's stroke is the distance the piston travels inside the cylinder. Stroke length is determined by the crankshaft. It can be listed in either inches or millimeters. How is it measured? The best way to find the stroke length is to: Identify the crankshaft. Brand, model, part number, and/or other information will be stamped or etched on ...
An engine's bore is the diameter of each cylinder, while the stroke is the distance within the cylinder the piston travels. Basically, an engine's maximum power depends on how many rpm it can...

The stroke length impacts the performance and efficiency of a pneumatic system and must be carefully considered during the design and selection process. This article discusses the significance of stroke length in a pneumatic cylinder, its calculation, and its types.
Explanation. Calculation Example: The stroke length of a hydraulic cylinder is the distance that the piston moves when the cylinder is fully extended. It is an important parameter in the design of hydraulic systems, as it determines the amount of force that the cylinder can generate. Related Questions.
Stroke is the distance the piston travels from the bottom to the top of the cylinder. Stoke is measured by rotating the crank so the piston is at Top Dead Center (TDC). The crank is then rotated 180 degrees to move the piston to Bottom Dead Center (BDC).
The bore and stroke on a cylinder determines the displacement of an engine, making bore and stroke a key element in determining engine power -- the larger the bore and stroke, the more powerful the engine. Bore and stroke are a combination of two measurements.
