高压涡旋喷油器喷雾撞壁机理研究(Spray Impingement Characteristic of GDI High-pressure Swirl Injector)
汽油缸内直喷 高压涡旋喷油器 喷雾撞壁 机理
2010/12/29
为了研究直喷式汽油机高压涡旋喷油器喷雾撞壁机理,测量了撞壁喷雾的高度、喷雾半径及喷雾远端速度,分析了不同喷射压力、环境背压、喷嘴到壁面的距离、壁面倾角等因素对撞壁喷雾的影响。随着喷射压力、喷嘴到壁面的距离及壁面倾角的增加,喷雾的贯穿距离增大;环境背压的增大导致喷雾的贯穿距离减小。较高的喷射压力和较低的环境背压增大了撞壁燃油与壁面的接触面积,在壁面上形成的薄膜加速了燃油的蒸发。由经验公式计算得到的撞...

2010/12/28
研究了压电式高压共轨喷油系统多次喷射过程中影响主喷油量波动的因素,采用EFS IFR8420型单次喷射仪对预喷和主喷的油量及喷油速率进行精确测量,总结了主喷油量波动的影响因素及其变化规律:预喷油量越小、主预间隔时间越短,主喷油量波动幅度越大,且随着主预间隔时间的增加,主喷油量呈周期性波动且波动幅度逐渐衰减。通过试验确定了预喷产生的压力波动是导致主喷油量波动的主要原因,为后续的多次喷射控制策略的设计...
