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

Green Car Congress

Thus, the researchers concluded, switching from PFI to GDI vehicles will likely lead to a reduction in net global warming. We estimate ozone and SOA formation potential. Therefore, the secondary organic aerosol and ozone formation potential of the exhaust does not depend on engine technology. —Saliba et al. of the data.
