Summary: The study aimed to improve the lubrication performance of synthetic lubricant by using MoS2-based nanoparticles. The results showed that the synthetic lubricant with added nanoparticles exhibited higher characteristics in some physicochemical properties, but marginally lacked in other properties. However, this synthetic lubricant had superior friction reduction and load-bearing capabilities, making it a potential substitute for shell lubricant.

Summary: Recent marine incidents have been partly caused by propulsion issues. Engine modelling techniques, specifically Artificial Neural Networks (ANN), have become an area of interest due to their accuracy and fast calculation times. However, most research has focused on predicting specific parameters for certain operation points. This study aimed to analyze the generalization capability of ANN in predicting multiple outputs in real engine conditions and successfully predicted 35 different performance and emission parameters.

Summary: In this study, performance and exhaust emissions of a direct injection diesel engine fuelled by diesel-jojoba-butanol blends were tested. The blend with 87% diesel fuel, 5% crude jojoba oil, and 8% butanol (DJ5B8) showed the best performance. Adding 5% hydrogen peroxide to DJ5B8 blend improved engine performance and exhaust emissions compared to other emulsified fuel ratios.

Summary: Day to day fuel prices are increasing due to fossil fuel depletion, industrialization, and technological development. This research investigates the impact of Moringa oleifera biodiesel-diesel-carbon black water emulsion blends on diesel engine characteristics. Experimental studies reveal that the B20-D75-CBWE5 mixture has the lowest fuel consumption and the highest thermal efficiency. B100 has the highest fuel consumption, but produces the least carbon monoxide, nitric oxide, and unburned hydrocarbon emissions at full load.

Summary: Biodiesel fuel has higher density, viscosity, and acidity compared to diesel fuel, leading to changes in metal pollutants concentration and efficiency in the long term. The study shows that Fe, Al, and Cr concentrations were lower in lubricants containing B100, while Cu and Pb metals were higher compared to B20 fuels. Additionally, Fourier Transform Infra-Red (FTIR) data indicates different absorption bands for hydrocarbon components in biodiesel fuel.

Summary: The presence of lubricant droplets in the gas flow of an internal combustion engine has significant implications for performance, including lubricant supply, oil consumption, and lubricant degradation. The viscosity of the lubricant and the presence of viscosity modifiers have been found to play a crucial role in the formation of droplets.

Summary: The tribological performance of the piston assembly of an automotive engine is influenced by the flow mechanisms that supply lubricant to the upper piston rings. The oil consumption, emissions, and wear in engines are affected by these mechanisms. Experimental studies suggest that droplets of lubricant carried in the gas flows through the piston assembly may contribute to this. This investigation measures the droplet size distribution in the crankcase of a fired gasoline engine and finds that higher base oil viscosity and the use of a polymeric viscosity modifier can reduce the proportion of mist-sized droplets, especially at high load.
