列型ポンプ使用の直噴式ディーゼルエンジン用燃料噴射系における燃料噴射率のシミュレーションおよび検証

抄録

In order to investigate the optimization of several parameters to control fuel injection rate on in line pump based fuel injection system for DI diesel engines, a computer model simulating the flow in fuel injection system was developed including a cavitation model for nozzle holes. For the validation of this model, comparison with experimental data was performed for a wide range of pump operating conditions. Following that successful validation of this model, parameteic studies were performed which could allow improved fuel injection system design.
