“…It was also reported that the engine head bench test was an unfired apparatus so it is difficult to account the effect of nanoparticles in an oxidizing atmosphere commonly present in Internal Combustion Engine. Nallusamy et al [147] in their study reported that the nanoparticles are extensively used to increase the thermal conductivity, heat transfer rate and tribological properties of the engine lubricant by adding nano-additives to form nanofluids. In order to reduce the friction and wear, lubricants are used, but still, the fuel consumed for frictional losses is about ten to twenty percentages of the total fuel supply.…”

Automotive manufacturers made significant efforts to achieve an overall increase in the energy efficiency and to reduce the toxic emission level. In the way to achieve these goals, non-conventional engine technologies were brought to the market with improved efficiency and controlled emission system. Numerous other supporting technologies which include biofuels and newly improved lubricants were also involved to contribute in automotive engine system improvement. The problem of friction and wear being inbred to the automotive application, further raise environmental hazards by way of more fuel consumption and wear debris. For several years there have been numerous efforts to reduce the amount of fuel consumed by automotive engines. Many of the solutions been strictly mechanical based. Other efforts have revolved around finding the lubricants that reduce the overall friction in the engine. Lubricants perform an anti-friction media which facilitate smooth operation, reduce friction, wear and risk of frequent failure. Due to this ever-increasing demand for lubricant, a considerable amount of work has been done to modify the lubricating oils with additives to enhance their overall properties. This review paper is aimed to highlight the research carried out in the field of lubricating oil with nano additives for the automotive applications.

“…The addition of CuO to the sunflower oil increased the coefficient of friction. Hence, it is very clear that the addition of nanoparticles may not always increase the tribological performance of the vegetable oils [26][27][28][29]. The optimum concentration of graphite to be added to the base oil is 0.1% weight.…”

Currently, nanofluids have been found to have enriched physical and thermal properties such as thermal conductivity, viscosity and convective heat transfer coefficients. The aim of this research is to analyse the performance characteristics of punga oil and plastic oil based nanolubricants. The nanoparticle of graphite with 0.1% weight was added to the base oils. Hydraulic oil of VG32 is used as standard oil to compare the performance with the nanolubricants. Basic properties such as viscosity, flash and fire point were measured for the prepared nanolubricants. Coefficient of friction for the selected oils was measured with help of reciprocating friction monitor and load wear index was also measured with the help of four ball tester. The performance of these oils for load ball bearing lubrication was carried out numerically with the help of Comsol software and its analytical validation was done with the help of MATLAB software. From the observed results it was found that, the power loss was decreased by about 77.4% and 78% by plastic oil and plastic oil based nanolubricant respectively and load carrying capacity was also decreased by about 78.3% and 78.8%.

“…Nanolubricants, a nanofluid class dedicated to lubrication, have shown success in reducing the wear and coefficient of friction in conventional ICE lubricants. [8][9][10][11][12][13] However, their performance has never been discussed and reviewed in terms of EVs' tribological conditions. This study explores the behaviour of various nanolubricants combinations composed of single or several types of nanoparticles (NPs).…”

The most remarkable difference between electric vehicles (EVs) and conventional ones is the fuel burning dependency of the internal combustion engine, while the emerging EVs operate on electric motors. These alternations create staggering shifts in both lubricants' market demand and performance specifications. Lubricants for electrical powertrain constitutes greases, transmission oils, and lubricants for auxiliary systems and do not rely on engine oils as internal combustion vehicles. The new standards will be more focused on lubricants' electrical properties such as breakage voltage and conductivity, coupled with tribological performance under high rpm, corrosion resistance and thermal management benchmarks. This paper thematically reviews the different studies performed with nanolubricants, and how they match EVs' operational requirements. Conclusions from this study can be considered as guidelines for the potential application of nanolubricants in EVs and possible future research that can be accomplished on the topic.
