Available in PDF, EPUB and Kindle. Book excerpt: The technical effort described herein was directed as evaluating the corrosion inhibitors (CI) currently approved under the MIL-I-25017D qualified products list (QPL). The thrust of the effort focused on the following: (1) establishment of relative effective concentrations for approved CI, (2) generation of working curves to profile CI performance in jet fuels, (3) development of an approach for incorporating a lubricity requirement into MIL I- 25017, (4) refinement of the reverse phase high performance liquid chromatography (RPHPLC) method for determining CI content in jet fuels, (5) determination of applicability of the RPHPLC to WPL CI, and (5) generation of an RPHPLC spectral library of WPL CI in JP-4. IPC-4410 was found to be among the most effective CI at improving the lubricity properties of jet fuels, while TOLAD 249 was shown to be the least effective. Pratt & Whitney found that a requirement for lubricity enhancement could easily be incorporated into MIL-I- 25017 with no significant effect on other criteria used in qualifying a candidate CI. The RPHPLC method for determining levels of CI in jet fuel was found to be applicable to all 15 QPL CI.

Available in PDF, EPUB and Kindle. Book excerpt: This report describes the evaluation of the effectiveness of corrosion inhibitors as fuel lubricity agents. The study was conducted with the Furey Ball-on-Cylinder. In the study, the eleven corrosion inhibitors from QPL- 25017-9 were evaluated as lubricity agents in three base fluids, at various concentrations, and at the two base fluid temperatures of 75F and 150F. The rank effectiveness of the inhibitors correlated for the following two cases: (1) The inhibitors at their maximum allowable concentration in the three base fluids at 75F. (2) The inhibitors at three concentrations in the same base fluid at 75F. The rank effectiveness of the inhibitors did not correlate for the case where the corrosion inhibitors were at their maximum allowable concentrations in the same base fluid but at the two different temperatures of 75F and 150F.

Download or read book Effect of Corrosion Inhibitors on Lubricity as Measured by the Ball On Cylinder Instrument written by Lourdes Q. Maurice and published by . This book was released on 1987 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report is an investigation to determine the effects of corrosion inhibitors on the lubricity of different types of fuels. The lubricity level of each fuel sample was measured using the Interav Ball-on-Cylinder Tester. The three most common inhibitors currently used by the Air Force (herein referred to as Corrosion Inhibitors C1, C2 and C3) were tested in petroleum and shale JP-4, JP-8 and isopar with and without other additives present. 'Normalization' procedures were used to evaluate inhibitor effectiveness relative to the wear scar of clay-treated fuels. Other additives were found to have effects on lubricity of fuel with corrosion inhibitor. Temperature variations of 13 degrees C had only a slight effect on fuel lubricity. Keywords: Jet fuel. (JG).
Download or read book Determining the Sensitivity of Fuel Lubricity Additive Concentration on HFRR Test Parameters written by Gregory A. T. Hansen and published by . This book was released on 2018 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: In diesel engines, fuel pumps and injectors are subjected to tremendous pressures that can reach upward of 200 MPa in modern systems. In order to generate and maintain this level of pressure, the internal pump and injector components are made to an exacting standard. The drawback is that the moving components are largely lubricated with just the diesel fuel. If the diesel fuel has insufficient lubricating quality, catastrophic wear and subsequent failures can occur., The US Army currently utilizes aviation turbine fuel in all of its diesel-powered ground vehicles. The current specifications outlined in MIL-DTL-83133, Turbine Fuel, Aviation, Kerosene Type, JP-8 (NATO F-34), NATO F-35, and JP-8 + 100 (NATO F-37), and ASTM D1655, Standard Specification for Aviation Turbine Fuels, allow specific synthetic fuel components that can exacerbate the lubricity issue (having both low viscosity and no aromatic content). With these synthetics, the High-Frequency Reciprocating Rig (HFRR) can have a wear scar diameter as high as 900 ?m, which, if run unadditized in an engine, will cause immediate hardware failure. The military requires the use of an approved lubricity additive in the fuel it acquires. If treated with an approved additive at a rate between 20 and 30 mg/kg, even these poor lubricity fuels will be able to operate in Army equipment for the life of the engine. Unfortunately, the HFRR wear result does not discriminate between these neat and additized fuels. This work was undertaken in an attempt to improve the correlation of HFRR-type wear scar results with pump test results for a series of fuels with varying levels of lubricity additive. The effects of varying test conditions are reported and conclusions drawn on how improvements could be made to the current lubricity testing standards.

This book was released on 1989 with total page 33 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objectives of this program were to develop laboratory bench fuel- wear test methodology using JP-8 and to evaluate the effects of additives to improve load-carrying capacity of JP-8 for use in diesel-powered ground equipment. A laboratory test using the Cameron-Plint High-Frequency Reciprocating machine evaluated the effects of various chemical and physical parameters influencing the lubricity of the distillate fuels. The test conditions were determined sufficient to eliminate the effect of fluid physical properties such as viscosity. It was shown that the differences in the intrinsic lubricity of the fuels were due to small amounts of chemical additives. Under such conditions, the test can be used as a screening tool to find additives for enhancement of JP-8 lubricity. The test has potential to ascertain minimum lubricity level for diesel-powered ground equipment if these requirements are verified with field performance data and determined to be different from the Air Force JP-8 specifications. The dimensionless wear coefficients of Reference No. 2 diesel fuel were shown to be an order of magnitude lower than the jet fuels. In all cases, the wear rates of jet fuels and isoparaffinic solvents were improved by addition of a corrosion inhibitor or antiwear additive to match the lower wear rates of the diesel fuels. Although there was no measurable change in the viscosities of the jet fuel due to the additives, the wear rates changed by an order of magnitude.

Available in PDF, EPUB and Kindle. Book excerpt: The U.S. Department of Defense has adopted the single fuel for the battlefield concept. Diesel fuel will be replace by JP-8/Jet A-1, which has both lower lubricity and viscosity. Currently, the tribological requirements of fuel- lubricated components in the injection system are unknown. As a result, no widely approved lubricity test or standard exists. Similar problems are currently faced in commercial applications where low-sulfur/aromatic fuels are bring introduced. The present study details the wear mechanisms likely to exist with low lubricity fuels, with particular reference to injection equipment known to be fuel sensitive. The wear mechanism was found to ba a function of contact severity and may not be uniquely defined by a single test. A number of potentially viable lubricity tests is suggested, and fuel/additive components are recommended for wear reduction.
