Download scientific diagram | Lubricity of the fluids evaluated by the HFRR method: (a) WSD (wear scar diameter) and (b) COF (coefficient of friction) and film percentage for the reference...

The High Frequency Reciprocating Rig (HFRR) was also developed in the 1990s to make it useful for evaluating diesel fuel lubricity. It can produce a wide range of wear mechanisms depending on the fuel being tested.

2017年11月15日 · In this paper, the lubricity of blends of conventional diesel fuel and ethanol, with ethanol content up to 14% (v/v), were tested. The HFRR (High-Frequency Reciprocating Rig) method was used for the research, which is a normative method of determining the lubricity of …

In this study, binary blends of palm oil biodiesel (POB) with commercial petroleum diesel fuel (DF) and HVO at every 10%-v/v blend point were analyzed using a high-frequency reciprocating rig...

2017年11月1日 · In this study the wear scar diameter (WSD) of 75 components is measured using the High-Frequency Reciprocating Rig (HFRR). The measured WSD values span a range from ca. 100 μm to more than 1100 μm.

采用高频往复试验机 (HFRR)评价柴油润滑性的方法是目前国际上广泛使用的方法和试验仪器。 BCM-01型柴油润滑摩擦磨损试验机可用于燃油和润滑油摩擦磨损性能的快速检测，如柴油、发动机油、润滑脂及其他油品的边界润滑状态下的摩擦磨损检测，可广泛应用于炼油厂，质检机构、科研院所等单位对柴油润滑性进行评定，也可用于其它油品或材料润滑性能的检测。 能满足ASTMD 6079 SH/T0765、ISO12156等测试方法标准测试柴油的润滑性能。 该设备采用工业控制计算 …

ASTM D6079-18《Standard Test Method for Evaluating Lubricity of Diesel Fuels by the High-Frequency Reciprocating Rig (HFRR)》代替D6079 – 11 (2016)，第一版发布于1999年。 柴油喷射装置对柴油的润滑性能有一定的依赖性。 发动机部件的寿命缩短，如柴油喷油泵和喷油器，有时被归因于柴油燃料缺乏润滑性。 HFRR试验结果导致柴油喷射系统泵组件磨损的趋势已经在一些燃料/硬件组合的泵钻机试验中得到证实，边界润滑被认为是影响组件运行的一个因素。 …

2000年6月19日 · Past studies of diesel fuel lubricity have used column chromatography to fractionate fuel components by polarity for testing in high-frequency reciprocating rigs (HFRRs). 7, 9 The HFRR test...

2025年2月25日 · 本文件规定了一种使用高频往复装置 (HFRR) 和数码相机的测试方法，用于评估石油基中间馏分燃料、石蜡柴油和生物柴油混合物的润滑性能，含或不含润滑增强添加剂，HFRR 磨损疤痕直径 (WSD) 为 350 μm 至 700 μm。 本测试方法适用于柴油发动机使用的燃料。 注意：尚不清楚此测试方法是否可以预测所有添加剂/燃料组合的性能。 本文件规定了一种使用高频往复装置 (HFRR) 和数码相机的测试方法，用于评估石油基中间馏分燃料、石蜡柴油和生物柴油 …

Koehler’s K93405 tests diesel’s lubricity by High-Frequency Reciprocating Rig (HFRR) technology. HFRR is a reciprocating friction and wear test system which is going under microprocessor control. It provides a fast and repeatable assessment of the performance of fuels and has become an industry-standard test for diesel fuel lubricity.
