Effects of Gasoline Properties on Cold Start Emission Characteristic

Event: Autumn Conference
The objective of this study is to clarify the difference of emission trends caused by the location of catalytic converter and gasoline property during Japanese cold start test. Japanese 11mode tests were carried out using two Japanese vehicles with the catalytic converter at the different location each other. The experimental result shows that most of all the amount of emissions were exhausted during early phase of 11 mode in which the catalytic converter was not activated. And THC emission trend was affected by the location of catalytic converter especially. T90 in fuel property affected THC emission, but the effect of T90 that was relatively smaller than the effect of the location of catalytic converter that cause catalysis temperature profiles.
