为了优化燃烧过程，优化发动机性能，满足美国环保局的排放标准，需要实时获取汽油的性质信息，目前汽油的供应范围很广，成分也不同。提出了一种基于声子晶体(PNC)腔体传感器的新型传感器平台，并将其应用于汽油性质在线实时检测系统中。该方法是基于对填充液体汽油混合物的声子晶体传感器的透射谱进行分析的。实验结果表明，声子晶体传感器可以被认为是一种有前景的、有竞争力的、廉价的、专门用于汽油检测和区分不同辛烷值燃料的乙醇传感器。(C)2013爱思唯尔B.V.保留所有权利。
In order to optimize the combustion process, engine performance and meeting the EPA emission standards, information should be gained in real time about properties of gasoline, which is supplied nowadays in a wide range with different compositions. This study presents a new sensor platform based on a phononic crystal (PnC) sensor comprising a cavity and its application as in-line real-time measuring system to determine gasoline properties. The method is based on the analysis of the transmission spectrum of a phononic crystal sensor filled with the liquid gasoline blend. We could reveal a strong correlation between gasoline properties and the frequency of maximum transmission.Obtained experimental results show that the phononic crystal sensors can be considered as a prospective, competitive and inexpensive device specifically for ethanol in gasoline detection and distinguishing fuels with different octane numbers.
