WebThe High Frequency Reciprocating Rig (HFRR) is a microprocessor-controlled reciprocating friction and wear test system which provides a fast, repeatable assessment of the performance of fuels and lubricants. It is particularly suitable for wear testing relatively poor lubricants such as diesel fuels and for boundary friction measurements of HFRR is a measurement for lubrication of Diesel or heating oil and stands for high frequency reciprocating rig. The value is given in μm, lower is better. The measured value is the diameter of the flattening of the ball after the test. It's important because high pressure injection pumps are only lubricated by the fuel itself. Density and viscosity are not sufficient describing the aptitude of the f…
