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

喷油器最近出现的问题是由于柴油机喷油器内部沉积物（IDID）造成的，因此，对燃油系统中此类沉积物的表征是全球的优先事项。这些存款已被证明是分层使用一些技术，最显着的飞行时间二次离子质谱法，并进一步聚焦离子束透射电子显微镜研究提供了一个网关技术，允许勘探这些层。将进一步发展这些和其他适当的技术，以提供了解矿床的起源和形成所需的关于矿床的详细资料。

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.
