Abstract Presented here are the thermophysical characterization and thermodynamic modelling of RAVENOL Calibration Fluid 2.5 which is used for the calibration and preservation of diesel engine fuel injectors. Accurate knowledge of the standardized fluid properties is an important component for engineering modelling to deliver the correct dose of fuel into the combustion chamber of diesel engines while reducing the occurrence of cavitation phenomena. The liquid density and specific isobaric heat capacity measurements were carried out up to T = 423 K at ambient pressure. The speed of sound moving through the liquid was measured from T = (300 to 423) K from ambient pressure up to p = 200 MPa. This plays a crucial role in fuel injection timing. With the combination of these data with high pressure, it is possible to accurately calculate the liquid density, specific isobaric heat capacity, coefficient of isobaric thermal expansion and isothermal compressibility at elevated pressures. The data obtained at ambient pressure were used to confirm the accuracy of the high-pressure experimental data by comparing them with the predictions of the Fluctuation-Theory Equation-of-State. The calibration fluid has become the second ISO 4113 fluid to be characterized in this fashion.

国际油标高温高压热物性测量及热力学建模:RAVENOL柴油轨喷油器标定液

摘要 这里介绍了用于柴油发动机喷油器校准和保存的 RAVENOL 校准液 2.5 的热物理特性和热力学建模。准确了解标准化流体特性是工程建模的重要组成部分,可将正确剂量的燃料输送到柴油发动机的燃烧室,同时减少气穴现象的发生。在环境压力下进行高达 T = 423 K 的液体密度和比等压热容测量。从环境压力到 p = 200 MPa,从 T = (300 到 423) K 测量穿过液体的声速。这在燃油喷射正时方面起着至关重要的作用。结合这些数据与高压,可以准确计算液体密度、比等压热容、等压热膨胀系数和高压下的等温压缩率。在环境压力下获得的数据用于通过将它们与波动理论状态方程的预测进行比较来确认高压实验数据的准确性。校准流体已成为第二种以这种方式表征的 ISO 4113 流体。
