An Investigation on Size Distribution of Exhaust Particulate Emitted from Gasoline Engine

Abstract:

Article Preview

This study is carried out to characterize the size distribution of exhaust particulate from gasoline engine. Accordingto the results,particulate number concentrations show bimodal size distribution including nucleation and accumulation mode below the range of 50nm in coldstarting. While in hot start state, number concentration with bimodal size distribution different from coldstarting are less than 40nm in size.The distribution of particulate number,surface area and particulate mass characterized by nucleation and accumulation distribution mode goes below 40nm,and the trends go up with the increase of engine speed.
