Editing Nitrous oxide engine (section)

==Terminology==
In the context of racing, nitrous oxide is often termed '''nitrous''' or '''NOS'''. The term NOS is derived from the initials of the company name '''Nitrous Oxide Systems, Inc.''' (now a brand of [[Holley Performance Products]]) one of the pioneering companies in the development of nitrous oxide injection systems for automotive performance use, and has become a [[genericized trademark]]. '''Nitro''' is also sometimes used, though incorrect, as it refers more to [[Nitro engine|nitromethane engines]].
