Editing Straight-five engine (section)

=== Engine balance and vibration ===
Five-cylinder engines have a [[Crankshaft#Internal combustion engines|crankshaft]] with 72 degree angles.<ref name="gimme">{{cite web |title=Gimme Five |url=https://www.hemmings.com/blog/article/gimme-five/ |website=www.hemmings.com |access-date=21 August 2022}}</ref> Amongst [[four-stroke engine]]s, an advantage of engines with five or more cylinders is that the power strokes are overlapping if the engine has an even [[firing order]].<ref name="car throttle" />

A disadvantage of the odd number of cylinders in a straight-five engine is it results in imperfect primary and secondary [[engine balance]], unlike a [[straight-six engine]] which has perfect primary and secondary balance. Counterweights on the crankshaft can be used to counteract some amount of these vibrations.  This method is also used in [[straight-four engine]]s.<ref name="BoschHandbook459_463">Robert Bosch GmbH, ''Bosch Automotive Handbook, 6th edition'' p. 459–463, Professional Engineering Publishing 2004, {{ISBN|1-86058-474-8}}.</ref><ref>Bednar, Fundamentals of Combustion, 1989</ref>
