To clarify the cause of big NOx deviation at zero kilometer of new vehicles equipped a CPF system, NOx storage effect was investigated by using NOx sensors which were installed before and after CPF. From these considerations, the main cause and the environmental influence of NOx storage effect will be investigated. In order to better elucidate the zero kilometer CPF vehicle emissions test procedure, a reasonable test procedure will be suggested.
