Editing Crankshaft (section)

===Piston stroke===
The distance between the axis of the [[Crankpin|crankpins]] and the axis of the crankshaft determines the [[Stroke (engine)#Stroke length|stroke length]] of the engine.<ref name="Howacarworks.com"/>

Most modern car engines are classified as "over square" or short-stroke,{{citation needed|date=August 2022}} wherein the stroke is less than the diameter of the [[cylinder bore]]. A common way to increase the low-RPM torque of an engine is to increase the stroke, sometimes known as "stroking" the engine. Historically, the trade-off for a long-stroke engine was a lower rev limit and increased vibration at high RPM, due to the increased piston velocity.<ref>{{cite web |title=All you need to know about stroker engines and kits |url=https://www.torquecars.com/tuning/stroker-engines.php |website=TorqueCars |access-date=28 August 2022 |date=22 December 2020}}</ref>
