Stroke (engine) - Wikipedia
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.
Bore and Stroke - NASA
2021年5月13日 · The distance traveled by the piston from zero degrees to 180 degrees is called the stroke - S of the piston. This explains why the Wright engine and modern automobile engines are called four-stroke engines .
What Does 'Stroke' Mean On An Engine - SlashGear
2024年9月26日 · When the piston moves all the way up in the cylinder (which mechanics call top dead center, or TDC), or all the way down (to bottom dead center, or BDC), that full movement in each direction is...
Stroke ratio - Wikipedia
Stroke ratio, today universally defined as bore/stroke ratio, is a term to describe the ratio between cylinder bore diameter and piston stroke length in a reciprocating piston engine.
What is an Engines Stroke Length? · Help Center - Summit Racing
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.
Four-stroke engine - Wikipedia
A stroke refers to the full travel of the piston along the cylinder, in either direction. The four separate strokes are termed: Intake: Also known as induction or suction. This stroke of the piston begins at top dead center (T.D.C.) and ends at bottom dead center (B.D.C.).
Understanding Piston Stroke: Definition, Types, And Importance
2024年3月23日 · The piston stroke refers to the movement of the piston within the cylinder of an engine. As the piston moves up and down, it plays a crucial role in the combustion process, converting fuel into energy to power the vehicle.
Main parameters of an engine piston and cylinder
The basic geometry of a piston (reciprocating) internal combustion engine is defined by the following parameters: compression ratio; ratio of cylinder bore to piston stroke; ratio of connecting rod length to crank radius (offset)
Piston Motion: The Obvious and not-so-Obvious, by EPI, Inc.
2021年12月16日 · The diameter of that path is the engine "stroke", which is the distance the piston moves from one end to the other end of its cylinder. The big ends of the connecting rods ("conrods") contain bearings ("rod bearings") which ride on the offset rod journals.
Piston stroke – what does the stroke mean for engine tuning?
What is piston stroke? The piston moves up and down in the cylinder. The path your piston takes between the top and bottom dead centre (TDC and BDC) is called piston stroke. The space in which the piston moves is the cylinder capacity and is …
