다국어 초록 (Multilingual Abstract)

Most gasoline engines employ a port injection system to achieve the better fuel-air mixing. A part of injected fuels adheres to the wall or intake valve and forms a film of liquid fuel. The other is secondarily atomized by the spray-wall interaction. A better understanding of this interaction will help in designing injection systems and control the strategies to improve engine performance and exhaust emissions.<br/>
In the present research, the spray-wall interaction was investigated by laser sheet visualization method, the shape of sprays was pictured at various impinging velocities and angles. The fuel dispersion was estimated by fluorescence light, and the atomization was evaluated by the enlarged images of droplets.<br/>
The experimental results were compared with model predictions which are based on OPT and TAB method. The models have been modified to have the better agreement with the experimental results, and are implemented in the KIVA-II code.
