...Gero Burghardt; Andrew Flórez; Georg Jacobs Purpose Wear particles and contaminants are known to reduce lifetime of machine elements such as roller bearings. This can be avoided through fine filtration. However, oil filterability can change in service, and in case of exceeding the maximum pressure...

...Alessandro Ruggiero; Miroslav Mindas; Lucia Knapcíková Purpose The paper aims to deal with the analysis of tribodiagnostic parameters of oil filter device to investigate the possibility to launch a thorough treatment of non-invasive filtration of oil during the full operation of machinery...

... test and field test data will be reviewed which show that by optimizing the base oil as well as the additive system, both synthetic as well as properly formulated mineral oil products can give excellent extended drain performance. With mounting economic pressures in the trucking industry, these new...

...C.W. Lea Contends that 40 years ago London Bus and other vehicle companies were using castor oil based fluids in their rear axles thereby obtaining major advantages in consumption of fuel owing to the excellently low coefficient of friction. Investigates a few specific applications drawn from...

...M. Eklund The response to antioxidants of different types (aminic, phenolic and sulphur‐based) has been evaluated for three base stocks intended for industrial lube production: a paraffinic solvent neutral, a hydrotreated naphthenic, and a naphthenic technical white oil. Furthermore, three...

...R. Schramm The use of energy‐dispersive X‐ray fluorescence in the oil industries increases continuously. The use of polarized X‐rays especially increased enormously the performance of this technology. The reduction of background decreases the limits of detection by up to a factor of 10...

... --> Hydraulics Oil Keep hydraulic oil "as new" with virtually unlimited life Keywords: Hydraulics, Oil The prospect of hydraulic oil being kept permanently in an "as new"condition, with a substantial increase in equipment response times, and up to a ten-fold increase in component life, is what...

...Hakan Kaleli Two 10W30 mineral‐base phosphorus containing (commercial) and phosphorus‐free (P‐Free) crankcase oils were tested in the engine dynamometer for the poisoning effects on a catalytic converter and emission‐engine’s performance. The emission results of the two oils were compared...

...P.S. Mukherjee Looks at the use of lubrication in the maintenance of mining equipment through the examination of five case studies of mines from different areas and their consumption of lube oil. Concludes that a suitable management of lubricant consumption plays an important role in production...

...Gary E. Newell This paper describes the development of the use of lubricant analytical programmes and trend analysis to optimise oil change intervals and to predict equipment failure. The various analytical methods are covered, as are the most frequently occurring lubricant applications where...

...Bill Wilson Defines the four main routes for reclaiming used oils ‐ recovery as fuel; reconditioning on site; oil laundering and re‐refining. Places used oil re‐refining in its historical context and presents profiles of the (only) two used‐oil re‐refiners in the UK. In 1993 Orcol Fuels started...

...Hakan Kaleli; Irfan Yavasliol The more frequently an engine oil is changed, the more the overhaul life of the engine is extended but with an increase in the cost both of the oil and of the oil drain services. If engine oil is changed less frequently the associated costs will decrease. In order...

...Luca Lazzeri; Franca De Mattei; Fiorenzo Bucelli; Sandro Palmieri The technical properties of Crambe abyssinica oil prompted the co‐operation between a research institute and a lubricant producer to determine some possible industrial applications. The results confirm the special physico...
