A '''naturally aspirated engine''', also known as a '''normally aspirated engine''', and abbreviated to '''N/A''' or '''NA''', is an [[internal combustion engine]] in which air [[intake]] depends solely on [[atmospheric pressure]] and does not have [[forced induction]] through a [[turbocharger]] or a [[supercharger]].<ref>{{cite web |title=What is a normally aspirated engine? |url=http://ask.cars.com/2008/09/what-is-a-norma.html |date=2008-09-02 |access-date=2015-10-18 |work=ask.cars.com |archive-url=https://web.archive.org/web/20130622020433/http://ask.cars.com/2008/09/what-is-a-norma.html |archive-date=2013-06-22 |url-status=dead }}</ref>
