基于胺类燃料示踪剂的激光诱导荧光是一种适用于内燃机混合研究的测量技术。三乙胺经常用于汽油内燃机;然而，没有详细的荧光特性的激发在263或266 nm是可用的。三甲胺（TMA）作为气体燃料示踪剂具有很高的潜力，但目前有关TMA荧光的信息很少。皮秒激光源与配备有摄谱仪的条纹相机相结合，用于确定两种示踪剂的光谱荧光发射和荧光衰减时间。示踪剂在不同的温度和压力下，在一个校准池与氮气作为浴气进行了研究。结果提供了一个深入的了解这两种示踪剂的荧光特性，并允许其应用程序的调查，在内燃机的燃料分布的评估。
Laser-induced fluorescence based on fuel tracers like amines is a suitable measurement technique for mixing studies in internal combustion (IC) engines. Triethylamine has often been used in gasoline IC engines; however, no detailed fluorescence characterization for excitation at 263 or 266 nm is available. Trimethylamine (TMA) exhibits high potential as a gaseous fuel tracer but little information about TMA fluorescence is currently available. A picosecond laser source combined with a streak camera equipped with a spectrograph was used to determine the spectral fluorescence emission and fluorescence decay time of both tracers. The tracers were investigated at various temperatures and pressures in a calibration cell with nitrogen as bath gas. The results provide an in-depth understanding of the fluorescence characteristics of both tracers and allow assessment of their application to the investigation of fuel distribution in IC engines.
