在一台单缸光学柴油机和多缸高速柴油机上，利用时间分辨激光诱导白炽光和电迁移率光谱仪技术进行了缸内和排气碳烟颗粒尺寸的测量。研究表明，在柴油机瞬时燃烧过程中，多分散纳米碳烟颗粒的激光诱导白炽光信号的时间衰减既可用单对数正态分布描述，也可用多对数正态分布描述。然而，在现有的模型中引入了多对数正态分布的粒度分布，以全面表征和逼真地重建粒度分布。对多对数正态分布进行了详细的理论分析，并将其应用于实验测得的碳烟颗粒尺寸。这些结果也被电迁移率光谱仪的实验结果和已发表的电子显微镜数据进行了定性的比较和独立的验证。这些结果表明，发动机缸内和排气碳烟颗粒尺寸分布更好地服从多对数正态分布。
In-cylinder and exhaust soot particle size measurements were carried out using time-resolved laser induced incandescence and electrical mobility spectrometer techniques in a single cylinder optical diesel engine and multi-cylinder high-speed diesel engine. The temporal decay of the laser induced incandescence signal from a polydisperse nanoparticle ensemble of soot during transient diesel combustion is shown to be described by both a single-lognormal distribution as well as multi-lognormal size distribution. However, a multi-lognormal particle size distribution is introduced in the existing model for a comprehensive characterisation and realistic reconstruction of the size distribution. Detailed theoretical analysis of multi-lognormal size distribution along with its application to the experimentally measured soot particle size is validated in this work. These results were also qualitatively compared and independently verified by the experimental results obtained by the electrical mobility spectrometer and published transmission electron microscopy data. These findings reveal that the in-cylinder and the exhaust soot particle size distributions in engines are better represented by a multi-lognormal size distribution.
