Where does N2O come from?
Nitrous oxide—the same “laughing gas” used as a dental anaesthetic and as a recreational drug in the form of “whippets”—was used in aircraft in World War II to provide additional oxygen to the engine and increase power. According to Hot Rod magazine, auto-racers adopted this technology in 1961. N2O is the gas’s molecular formula in chemistry, formally written as N²O.
In the 1970s, the company Nitrous Oxide Systems (NOS for short) was founded, specializing in the technology. The brand was featured in Road & Track in 1982. By the mid-1980s, nitrous was in use as shorthand for nitrous oxide. By the early 1990s, NOS was used to describe the gas itself, acting as a generic term for nitrous oxide in addition to a brand name. Beginning in 2001, NOS was referenced in the Fast and Furious movie series, in the generic sense as well as in product placement. In 2005, NOS licensed its brand for an energy drink by the same name.
Nitrogen dioxide, or NO2 or NO², was known to scientists by the late 19th century. The gas was known as a pollutant by 1965, when the Journal of the Air Pollution Control Association discussed emissions standards for the chemical, among others. A company called VP Racing Fuels also produces a high octane fuel under the name NO2, designed for engines using nitrous oxide.
Who uses N2O?
Nitrous and NOS are often used by car enthusiasts and in the racing community, where the latter acronym is colloquially pronounced like “noss.” N2O is used by these groups but also by others including doctors. Due to its popular use, the originally proprietary NOS has become a genericized term for nitrous oxide.
NO2 is sometimes mistakenly used in place of N2O to refer to nitrous oxide, although it is the molecular formula for a different chemical.
