This study investigated the tribological behaviour of Pongamia oil (PO) and 15W–40 mineral engine oil (MO) with and without the addition of graphene nanoplatelets (GNPs). The friction and wear characteristics were evaluated in four-ball anti-wear tests according to the ASTM D4172 standard. The morphology of worn surfaces and the lubrication mechanism of GNPs were investigated via SEM and EDS. This study also focuses on the tribological effect of GNP concentration at various concentrations. The addition of 0.05 wt % GNPs in PO and MO exhibits the lowest friction and wear with 17.5% and 12.24% friction reduction, respectively, and 11.96% and 5.14% wear reduction, respectively. Through SEM and EDS surface analysis, the surface enhancement on the worn surface by the polishing effect of GNPs was confirmed. The deposition of GNPs on the friction surface and the formation of a protective film prevent the interacting surfaces from rubbing, resulting in friction and wear reduction.

In this paper, an attempt was made, to evaluate the tribological performance of Jatropa oil with addition of nanoparticles, on wear reduction in Al 6082 and it was compared with SAE20W40 engine oil. Experiments were conducted with pure Jatropa oil with different weight percentage of TiO2 nanoparticles such as 0%, 0.1%, 0.3% and 0.5%. The coefficient of friction and specific wear rate of the Al specimens were found by using pin on disc tribo-meter as per ASTM G99 standards, at constant speed of 1m/s using different loads such as 20N, 40N and 60N. The experimental results indicated that the addition of TiO2 with Jatropa oil indicated good friction reduction and anti-wear properties, compared to SAE20W40 engine oil. The lubricant viscosity and thermal conductivity were measured using Redwood viscometer and Transient hot wire method. Surface analysis was done using scanning electron microscopy to the study surface morphology of pin material. Surface examination revealed that TiO2 Nanoparticles lead to smoother worn surfaces than commercial Engine oil SAE20W40.

Tribology and solid mechanics are essential when studying engine lubrications. Very reproducible boundary lubrication tests were conducted as part of Design of Experiment software (DOE) to study the behavior of fluorinated mix in developing environmentally friendly (reduced P and S) anti-wear additives for future engine oil formulations using ball on cylinder testing protocol. In this study fully formulated oil and ZDDP plain oils were tested under the protocol of two cycles. A 100 rpm cycle was used for the first 5000 revolutions and a 700 rpm cycle was used until failure or 100000 revolutions whichever comes first. All tests were generated under extreme boundary lubrication (Hertzian contact pressure of 2.72 GPa). Design of Experiment (DOE) with 2 level factorial was used to investigate the failure and wear responses with respect to fluorinated mix interactions in plain and fully formulated oils. The two cycle’s tests indicate better performance than the one cycle test. Findings indicate that the most significant factors, affecting friction and wear are fluorinated mix concentrations together with oil formulation.

Base oil plays an important role in engine oil formulation in delivering overall performance attributes in addition to additives. Non-traditional base oil like polyalkylene glycol (PAG) did not get much attention in the past for formulating automotive engine oil. This investigation explored PAGs for enhancing engine oil performance primarily for fuel economy benefit over traditional mineral oil-based formulations. This paper highlights key findings from an extensive investigation, parts of which were published in detail elsewhere, and identifying opportunities and challenges. Several PAG chemistries were investigated depending on their feedstock material. Friction performance was evaluated by several methods starting with laboratory bench tests to engine components to chassis roll dynamometer tests. Durability was also evaluated from laboratory bench tests to engine components to ASTM sequence tests. The investigation revealed that significant friction reduction or fuel economy gain can be achieved with PAG oil but wear protection capability, piston deposit, and varnish require much improvement requiring identification/development of additive components. A few alternative routes for performance improvement are suggested.
