Vegetable oils are being investigated as potential source of environmentally favorable lubricants over synthetic products. Jatropha curcas L. oil (JO) identified as a potential raw material for biodiesel was explored for its use as a feedstock for biolubricants. Epoxidized jatropha oil (EJO) was prepared by peroxyformic acid generated in situ by reacting formic acid and hydrogen peroxide in the...

The paper presents the results of a study sliding friction process porous material based on iron impregnated with lubricating oil dispersed particles fluorinated graphene. It is established that regularities kinetics external have sigmoidal and sigmoidal-linear character. Experimental been obtained showing an increase in concentration aggregates from flakes graphene oil, average force coefficie...

The oil film behavior of a series of fifteen lubricating oils was tested in a single cylinder spark ignition engine. The oil film thickness between the piston and cylinder liner of this engine was observed using the Laser Induced Fluorescence (LIF) technique. The data was examined for correlations between physical properties of the oil and characteristics of the oil film. The region of the oil ...

The paper proposes a novel nano bearing formed by the physical adsorption of the confined fluid to the solid wall. The bearing is formed between two parallel smooth solid plane walls sliding against one another, where conventional hydrodynamic lubrication theory predicted no lubricating effect. In this bearing, the stationary solid wall is divided into two subzones which respectively have diffe...
