柴油机喷雾过程的相似模拟

从理论上分析了柴油机喷雾过程的相似模拟；在较低的缸内压力、采用“模拟燃料”以及对应的喷孔直径条件下，导出了模拟实际柴油机喷雾过程的相似模拟条件。在实际柴油机的实机和模拟工况下，采用正戊烷、正己烷作为模拟工况的模拟燃料，模拟实际柴油机的工况。采用瞬时取样技术与双曝光全息干涉法，分别对实机工况与模拟工况喷雾过程进行定量测定，验证了本文所导出的相似模拟条件

Analog Simulation of the Process of Diesel Spray

Basing on the analog theory the author researched the analog simulation of the process of diesel spray.The conditions of the analog simulation of fuel spray in a real engine were deduced.The real engine conditions could be simulated with an adaptive simulation fuel at a low cylinder pressure and the hole of sprayer.The concentrations of fuel spray in both the real engine and the simulative engine conditions have been quantitatively measured by sampling technique and holographic interferometry method.The results from different conditions confirmed the analog simulative conditions deduced by the author of this paper.
