Study finds fleet switch from PFI to GDI engines will result in net reduction in global warming

Green Car Congress

We use the data to quantify the effects of engine technology, emission standards, and cold-start on emissions. Finally, we analyze the potential climate effects of switching a PFI to a GDI fleet. All the vehicles were tested using commercial gasoline that met the summertime California fuel standards. —Saliba et al.
