With the extensive use of internal combustion engines, the large volume of lubricant consumption has become an urgent problem. In this study, a new adsorbent of modified sawdust (MS) was used to clean the waste diesel engine lubricant and prepared into a pure biomass oil filter (PBF) for the actual operation of buses. The characterization results of sawdust showed that the crystallinity index of MS enhanced 19.26%, and MS had smoother morphology, obvious pores than raw sawdust (RS). In on‐road tests, both total acid number (1 mg KOH·g−1) and total base number (9 mg KOH·g−1) were within the permitted range of the standard, and the kinematic viscosity showed a decreasing trend. In addition, the concentration of metals and insoluble colloids (<0.2%) in the lubricant was far below the oil change limit, which made the oil drain interval of the two vehicles extended from 15 000 km (recommended by manufacture) to 60 500 and 71 500 km, respectively. Conclusively, it is believed that PBF is efficient to alleviate lubricant deterioration and prolong the oil drain interval.

“…While these fluids are performing their functionality of providing required boundary lubrication, their efficient functioning life has been usually estimated by a “thumb-rule” that was related to their cycles or period of usage. Unless an oil sample was removed and investigated by using several analytical techniques specific to the application [ 1 , 2 ], the exact remaining effective lifecycle of the fluid is difficult to be accurately estimated [ 3 , 4 , 5 ]. Over the past few decades, several ingenious methods have emerged for oil monitoring systems, which have been spearheaded by industrial research and development (R & D) [ 6 , 7 , 8 , 9 ].…”

Performance Analysis of Retrofitted Tribo-Corrosion Test Rig for Monitoring In Situ Oil Conditions

et al. 2017

Oils and lubricants, once extracted after use from a mechanical system, can hardly be reused, and should be refurbished or replaced in most applications. New methods of in situ oil and lubricant efficiency monitoring systems have been introduced for a wide variety of mechanical systems, such as automobiles, aerospace aircrafts, ships, offshore wind turbines, and deep sea oil drilling rigs. These methods utilize electronic sensors to monitor the “byproduct effects” in a mechanical system that are not indicative of the actual remaining lifecycle and reliability of the oils. A reliable oil monitoring system should be able to monitor the wear rate and the corrosion rate of the tribo-pairs due to the inclusion of contaminants. The current study addresses this technological gap, and presents a novel design of a tribo-corrosion test rig for oils used in a dynamic system. A pin-on-disk tribometer test rig retrofitted with a three electrode-potentiostat corrosion monitoring system was used to analyze the corrosion and wear rate of a steel tribo-pair in industrial grade transmission oil. The effectiveness of the retrofitted test rig was analyzed by introducing various concentrations of contaminants in an oil medium that usually leads to a corrosive working environment. The results indicate that the retrofitted test rig can effectively monitor the in situ tribological performance of the oil in a controlled dynamic corrosive environment. It is a useful method to understand the wear–corrosion synergies for further experimental work, and to develop accurate predictive lifecycle assessment and prognostic models. The application of this system is expected to have economic benefits and help reduce the ecological oil waste footprint.

“…Diesel engine main bearings can run fasterF and bear a larger load [10][11][12][13]. Elastic deformation on the surface contact of bearings, as well as the bearings themselves, can affect oil film thickness, oil film pressure, and the force and power consumption of friction, thereby affecting the lubricating properties of the main bearing [14][15].…”

In this paper, flexible multi-body dynamics was coupled with elastohydrodynamic lubrication of main bearings to study the lubricating properties of diesel engine main bearings. Data of bearing forces for diesel engine main bearings under rated conditions and cylinder 1 misfired conditions were analyzed, to provide a basis for the tribology design of a main bearing friction pair and the system optimization of a diesel engine. The result showed that single cylinder misfire had a greater influence on the two adjacent main bearing loads and the axis orbits of the two adjacent main bearings, but less effect on the other main bearing load and axis orbits of the other main bearings.
