e/Stroke ratio

Information
has gloss	eng: In a reciprocating piston engine, the stroke ratio, defined by either bore/stroke ratio or stroke/bore ratio - are terms which are used to describe the relationship ratio between the diameter of the cylinder bore, and the length of the piston stroke - within its cylinders. This can be used for either an internal combustion engine, such as a petrol- or diesel engine, where the fuel is burned within the cylinders of the engine - or external combustion engine, such as a steam engine, where the combustion of the fuel takes place outside the working cylinders of the engine.
