喷油引起的轨道压力波动被证明是导致喷雾发展不均匀的原因。这些波动还导致了较低的喷射压力，从而损害了喷嘴的穿透长度和破裂时间。尽管有大量文献涉及这类问题，但钢轨压力波动的几个方面仍然不清楚。此外，遵守排放法规的必要性揭示了替代燃料的潜力，这是实现可持续机动性的一条途径。这一情况促使本研究处理与燃料特性相关的钢轨压力时间历史的评估。试验使用了最后一代共轨喷射设备，在不同的喷射设置下，使用了柴油和2-甲基呋喃-柴油混合物。本文介绍了这一研究活动，旨在为钢轨压力波动与燃料性质的相关性提供新的见解。
Injection-induced rail pressure fluctuations are proven to cause nonuniform spray development. These fluctuations are also responsible for generating lower injection pressures, to the detriment of jet penetration length and break-up timing. Despite the vast literature dealing with such issues, several aspects of rail pressure fluctuations remain unclear. Additionally, the need for compliance with the emission legislation has shed light on the potential of alternative fuels, which represent a pathway for sustainable mobility. This scenario has motivated the present study dealing with the assessment of the time history of rail pressure correlated with fuel properties. Tests have been performed using a last-generation common rail injection equipment under various injection settings, employing diesel and 2-methylfuran-diesel blend. This paper describes the research activity and aims to provide new insights into the correlation of rail pressure fluctuations with fuel properties.
