Effects of injector deposit on spray and air/fuel mixing process were investigated. Injector deposit altered the designed spray structure and droplet behaviours. Injector deposit led to severe fuel impingement in the late injection cases. Over rich zones found for the coked injector can lead to higher emissions.
