文摘
- •
Soot formation was quantified in spray combustion under DISI-conditions in a CVC.
- •
Laser induced incandescence and laser extinction measurements were coupled.
- •
Soot is mainly formed in the spray front due to droplet combustion.
- •
20">Increased sooting tendency of E20 compared to pure isooctane and gasoline.
- •
Physical fuel properties govern soot formation mechanisms in E20 mixtures.
