The upside of gasoline direct injection (GDI) engines is widely seen as being improved fuel economy coupled with an increase in specific power (especially with turbocharging), enabling significant downsizing. The extent of fuel-air mixing can be affected by injection system design. A significant fraction of the GDI PM 2.5
