Advanced Characterisation of Deposits in Fuel Systems using Surface Analysis Techniques in conjunction with High Resolution Mass Spectrometry

最近喷油器的问题被认为是由柴油内部喷油器沉积物（IDID）引起的，对燃料系统中这种沉积物的表征是世界范围内的一个优先事项。这些沉积物已被证明是分层的，使用了许多技术，最值得注意的是飞行时间二次离子质谱法，进一步的聚焦离子束透射电子显微镜研究为探索这些层提供了一种门户技术。将进一步发展这些和其他适当的技术，以提供了解矿床起源和形成所需的详细资料。

Recent problems with injectors have been attributed to internal diesel injector deposits (IDID) and characterisation of such deposits in fuel systems is a priority worldwide. These deposits have been shown to be layered using a number of techniques, most notably time of flight-secondary ion mass spectrometry, and further focused-ion beam transmission electron microscopy studies have provided a gateway technique to allow exploration of these layers. These and other appropriate techniques will be further developed to provide the detailed information on deposits that is need to understand their origin and formation.
