Editing Detonation (section)

== In engines and firearms ==
Unintentional detonation when [[deflagration]] is desired is a problem in some devices. In [[Otto cycle]], or gasoline engines it is called [[engine knocking]] or pinging, and it causes a loss of power. It can also cause excessive heating, and harsh mechanical shock that can result in eventual engine failure.<ref>{{Cite web |url=https://www.hpacademy.com/technical-articles/dont-waste-your-time-listening-for-knock/ |title=Don't Waste Your Time Listening for Knock... |website=High Performance Academy |first=Andre |last=Simon }}</ref> In firearms, it may cause catastrophic and potentially lethal failure{{citation needed |date=December 2021 }}.

[[Pulse detonation engine]]s are a form of pulsed jet engine that has been experimented with on several occasions as this offers the potential for good fuel efficiency{{citation needed |date=December 2021 }}.
