TY - CONF A1 - Woydt, Mathias T1 - Lifetime lubricated engines using triboreactive materials T2 - The control and reduction of wear in military platforms N2 - By means of an analysis of future trends in engine oil specifications with the associated consequences for the functional properties performed by base oils and individual additives, the need and potential application of alternative fluids and triboactive materials or lubricious oxides will be displayed. Oxidation resistance and low volatility represent key elements to assure long drains or lifetime lubrication in order to minimize or avoid manual or automatic top-ups. The intrinsic properties of base oils and the additive package define the oxidation resistance and related oxidative volatility. The overall engine oil consumption is also related to design (clearances, thermal stability of geometries, seals,...) and bore surface finishing and are not regarded here. Lubricious oxides or triboactive materials and/or polar base oils substitute the EP and AW properties realized by the additives, thus enabling long drains and responding to "eco-tox" or "bio-no-tox" requirements as well as restrictions from the "chemical box".
