In order to help one judge the friction properties of lubricating oils without tests, this paper intends establish correlation between characteristic parameters and properties. The elastohydrodynamic boundary poly alpha olefin (PAO) synthetic oil, polyol ester oil paraffin-based mineral were tested using a Mini-Traction Machine. Fourier transform infrared microscopy is used identify material ch...

The four-ball tester was used in this analysis to demonstrate the lubricity of tire pyrolysis oil (TPO). tribological performance compared with diesel fuel (DF) and their blends, DT10 (TPO 10%, Diesel 90%) DT20 20%, 80%). A scanning electron microscope (SEM) investigate wear scar. In contrast fuel, TPO demonstrated better antiwear behaviour terms higher load-carrying capacity. DT10, DT20, TPO’s...

Anti friction bearings in process pumps, by design, frequently utilize oil sump lubrication technology. For many years, it was an accepted condition that the lubricating oil used in oil sump bearing lubrication needed to be changed on a regular basis to prevent high levels of contamination that can lead to premature bearing failure, contributing to equipment downtime. Often, the indicators used...

This Article describes the use of capillary pressure to initiate and control the rate of spontaneous liquid-liquid flow through microfluidic channels. In contrast to flow driven by external pressure, flow driven by capillary pressure is dominated by interfacial phenomena and is exquisitely sensitive to the chemical composition and geometry of the fluids and channels. A stepwise change in capill...

The growing trend of increasing biodiesel concentrations in diesel fuel blends has led to concerns about its effect on the oxidation formulated oils within internal combustion engines. We observe that is not only susceptible rapid at elevated temperatures but also responsible for acceleration process lubricant base oil when presence soluble iron; this supported by a range control and model expe...

Plastic wastes, lube oils and coal-tar are evaluated, individually and combined, as additives to coal blends for the production of blast-furnace coke. The effects of adding 2 wt% of potential additives or their mixtures (50:50 w/w) on the coking capacity of coal, the pressure generated during the coking process and the coke quality parameters were evaluated. Using a combination of polyolefin wa...
