Droplet size distribution and evaporation characteristics of fuel spray by a swirl type atomizer

Abstract: 8Spray atomization and evaporation play extremely important roles in mixture formation and combustion 9 processes of direct injection (DI) gasoline engines. In this study, the fundamental characteristics of a swirl spray 10 injected into a constant volume vessel are investigated by means of several laser diagnostic techniques including the 11 laser diffraction-based method for droplet size distribution, the laser induced fluorescence-particle image velocime-12 try for velocity distributions of droplets and spr… Show more

“…They stated the evaporation of a spray could be explained by the atomization and evaporation of a single droplet. Li et al [12] mentioned that evaporation played an essential role in the mixture formation and the combustion process of direct injection gasoline engines. Ji et al [13] experimentally proved that starting a spark-ignited (SI) engine with pure DME could improve the combustion and emissions performance.…”

“…Either the partial combustion or misfire, which increases the variation in the engine cycle, occurs owing to the effect of the liquid fuel on the spark electrodes. [5][6][7][8] Since a suitable mixture formation plays a pivotal role in the SG-DISI engine, numerous studies have been carried out on the flow, the fuel mixing near the spark plug and the ignition process. [9][10][11][12] Furthermore, the impact of using a multi-hole injector as an effective method for a flexible and stable spray structure for DISI engines to reduce the cyclic variation has been reported.…”
