| Ringkasan: | Precise control of fuel injection is essential in modern diesel engines especially in
controlling the precise injection quantity, flexible injection timing, flexible rate of injection with
multiple injections and high injection pressures. It was known that the fuel-air mixing is mainly
influenced by the fuel injection system and injector nozzle characteristics. Thus, mixture formation
during ignition process associated with the exhaust emissions. The purpose of this study is to
investigate the influence of spray characteristics on the mixture formation. In this study, common
rail injector systems with different model of injector were used to simulate the actual mixture
formation inside the engine chamber. The optical visualization system was constructed with a
digital video camera in order to investigate the detailed behavior of mixture formation. This method
can capture spray penetration length, spray angle, spray evaporation and mixture formation process
clearly. The spray characteristic such as the penetration length, spray angle and spray area are
increasing when the injection pressure increased. The mixture formation can be improved
effectively by increasing the injection pressure. |
