Visualization test for spray development process in diesel engine

摘要：

With the spray combustion visualization test unit, researches have been made on the spray development process under different injection pressures with STD nozzles, VOC nozzles and IMPROVED nozzles of diesel engines. The result shows that with the rise of injection pressure, the spray cone angle increases slightly, and corresponding to the same injection moment, the penetration enlarges accordingly with the rise of injection pressure. The cone angle is narrow for STD type, while it becomes wider for VCO type, but meanwhile the penetration decreases and the spray shape is sharply changed. The IMPROVED nozzle combines features from both STD and VCO nozzles, promising the excellent performance of STD nozzle with virtually no penetration decrease and spray shape change.
