A method capable of decreasing the amount of NOx generated by the combustion of a gas generating agent for an air bag. A method for reducing NOx generated by the combustion of a gas generating agent of an air bag by a reducing material placed inside an inflator and decreasing its amount. NH2radical, or the like, is generated by the decomposition of the reducing material. The radical is allowed to react with NOx and a part of NOx is changed to the N2gas. Thus, the amount of NOx is decreased.
1. A method of reducing NOx, the method comprising: burning a gas generating agent to produce a combustion gas including NOx inside an inflator for an air bag, the inflator comprising an ignition means, a gas generating agent, a partition plate and a coolant/filter; and contacting the NOx with a reducing material comprising 5-aminotetrazole, wherein the gas generating agent and the partition plate are accommodated in a combustion chamber, and the gas generating agent and the reducing material are separated by the partition plate. 2. The method acc...
