Title :ディーゼル燃料噴射ノズル噴孔近傍における超高密度液滴の分裂を評価可能な分析計の開発
Authors :駒田 佳介

Abstract :The high-pressure fuel generator was developed for the generation of high-pressure fuel spray. When the target pressures of common rail at the high-pressure fuel generator were set at 60, 80, 100 and 120 MPa, and the mean pressures of actual pressure of common rail were 60.04, 80.04, 100.10 and 119.85MPa respectively. Moreover, the measurement system, that is, a laser 2-focus velocimeter (L2F) was developed for the evaluation of breakup of droplet inside the diesel fuel spray. The L2F has a micro-scale measuring volume which consisted of two foci. The focal diameter was about 3 μm, and the distance between two foci was 20 μm. The velocity and size of droplets inside the spray can be measured by using L2F. The maximum data sampling rate of the L2F system was markedly high as 15 MHz.
