had a little look through my notes,

average level of fuel atomisation in GDI engine is 20-50 microns.
It is a design LAW that those droplets should not hit the wall. V bad if it does.
And charge that hits wall will evapourate as the wall is at 500c. Evapouration means that you may have some fuel in exhaust due to low AFR in air.
