| Abstract(E) | Ambient conditions around a vehicle affect the emission characteristics. The emission characteristics of Nitrous oxide (N2O) under various ambient temperature conditions have been reported by other papers, but the effect of ambient humidity has not been focused on. In this report, the effect of ambient humidity on N2O emissions from a gasoline vehicle was investigated using a chassis dynamometer. As a result, N2O emissions decreased as ambient humidity increased. Furthermore, ambient humidity during preconditioning also affected N2O emissions at the start of the homologation test. |
