我们报告的观察，从实验轻型柴油发动机，产生不同水平的生物柴油燃料混合的碳烟的纳米级微观结构的变化。基于这些观察和文献中的当前信息，我们提出了一个机械假说来解释生物柴油混合的影响。我们的基本假设是，微粒纳米结构是密切耦合到当地的化学在烟灰形成的时候。在缸内碳烟形成的背景下，这意味着纳米结构的变化可能有助于诊断燃料-空气混合的重要变化。
We report observations of nanoscale microstructural changes in soot from an experimental light-duty diesel engine, produced with varying levels of biodiesel fuel blending. Based on these observations and current information in the literature, we propose a mechanistic hypothesis to explain the effects of biodiesel blending. Our underlying assumption is that particulate nanostructure is closely coupled to the local chemistry at the time the soot is formed. In the context of in-cylinder soot formation, this implies that changes in nanostructure may aid in diagnosing important changes in fuel–air mixing.
