Nitrous oxide inside the cells, by a process catalyzed by the enzyme nitrous oxide reductase. Nitrous oxide has significant global warming potential as a greenhouse gas. On a per-molecule basis, considered over a 100-year-period, nitrous oxide has 298 times the atmospheric heat-trapping ability of carbon dioxide (), however, because of its low concentration (less than 1/1000 of that of ), its contribution to the greenhouse effect is less than one-third that of carbon dioxide, and also less than water vapour and methane. On the other hand, since 38% or more of the entering the atmosphere is the result of human activity, and
Nitrous oxide engine War II usage of nitrous oxide injector systems were modifications of Merlin engines carried out by the Heston Aircraft Company for use in certain night fighter variants of the de Havilland Mosquito and PR versions of the Supermarine Spitfire. Nitrous oxide engine A nitrous oxide engine is an engine which requires oxygen for burning the fuel in order to create power (mainly stems from the decomposition of nitrous oxide (NO) rather than air). The system increases the internal combustion engine's power output by allowing fuel to be burned at a higher-than-normal rate, because of the higher partial pressure of oxygen
