Abstract

Particulate Matter (PM) emissions from passenger vehicles have attracted considerable interest over
the last decade. In order to reduce PM emissions, improving maximum injection pressure has been a
developing trend for new generation GDI engines. However, comparing gasoline and ethanol
impingement spray characteristics from a GDI injector under high injection pressure is still unclear.
In this paper, a comparative investigation on both the macroscopic and microscopic characteristics of
impingement spray from a GDI injector fuelled with gasoline and ethanol was performed under
injection pressure up to 50 MPa, providing new findings to promote a more homogeneous air-fuel
mixture and reduce PM emissions. The experimental results show that under the same
