| 1. | It has been difficult to solve problems associated with the thermal protection of the interior chamber walls . 在解决燃烧室内壁表面隔热问题上曾经遇到困难。 |
| 2. | High frequency instabilities result in grossly increased convective heat transfer coefficients in the chamber walls . 高频不稳定性使室壁对流传热系数大大增加。 |
| 3. | Although the presence of fuel-rich boundary injection apparently degrades engine stability, it is generally necessary to enhance chamber wall endurance . 尽管富燃料边界喷射的存在显然降低了发动机的稳定性,但通常这是为增强室壁的耐久性所必需的。 |
| 4. | Short and narrow packing chamber . sealing effectiveness improves as overall packing length shortens . chamber wall is burnished for superior finish 又短又窄的填料腔。总的填料长度缩短改善了密封的有效性。腔壁具有相当的光洁度。 |
| 5. | Through improvement of construction technology of chamfer of zaohe river third - line lock ' s chamber wall , the inclined surface concrete quality has been well controlled 通过对皂河三线船闸闸室墙倒角施工工艺的改进,斜面砼表面质量得到了较好的控制。 |
| 6. | The energy equation of the thrust chamber wall was developed by omitting radical heat conduction and only considering the radiation heat transfer of the four chambers , the radiation leakage through nozzle exit , the axial and circular heat conduction 忽略径向导热,考虑推力室外向的相互及自身辐射交换、内壁经喷口的辐射泄漏以及周向和轴向的传导热量,建立了推力室壁的能量方程。 |
| 7. | The last or main injection pulse is set around tdc . when the diesel spray impinging on the combustion wall , the bump around the combustion chamber wall can strip off the wall jet and form a secondary spray in combustion chamber , so the fuel and air can mix well and homogenous 在主喷射时刻,利用燃烧室壁面的bump迅速剥离壁面射流,在空间形成二次射流,二次射流进入燃烧室空间后,再一次与空气混合,形成相对均匀的稀混合气。 |
| 8. | Referred and analyzed the developing and researching achievement of high turbulent combustion chamber on diesel engine in the world , the grooved combustion chamber is designed and developed based on the rationale of designing high turbulent combustion chamber and employed the effect of the grooved of the combustion chamber wall on the spray impingement 在分析和参考国内外柴油机高紊流燃烧系统开发研究成果的基础上,根据高紊流燃烧室设计的理论基础,利用矩形环槽对燃油喷雾撞壁效应能加速混合气形成的机理,设计开发了在燃烧室侧壁上加工有矩形环槽的燃烧室方案。 |
