“…Higher in-cylinder temperature and availability of oxygen are responsible for the formation of Nox in compression ignition engines. Hence, water in biodiesel emulsions has been tested for increased thermal efficiency and a reduction in the formation of Nox [30][31][32][33][34][35]. There was a reduction of 32% in formation of Nox, a 7.4% reduction in smoke, and a 2.3% and 1% reduction in CO and hydrocarbon (HC) were reported when water emulsified pongamia biodiesel was used in a 4-S diesel engine [36].…”

The ever-increasing demand for transport is sustained by internal combustion (IC) engines. The demand for transport energy is large and continuously increasing across the globe. Though there are few alternative options emerging that may eliminate the IC engine, they are in a developing stage, meaning the burden of transportation has to be borne by IC engines until at least the near future. Hence, IC engines continue to be the prime mechanism to sustain transportation in general. However, the scarcity of fossil fuels and its rising prices have forced nations to look for alternate fuels. Biodiesel has been emerged as the replacement of diesel as fuel for diesel engines. The use of biodiesel in the existing diesel engine is not that efficient when it is compared with diesel run engine. Therefore, the biodiesel engine must be suitably improved in its design and developments pertaining to the intake manifold, fuel injection system, combustion chamber and exhaust manifold to get the maximum power output, improved brake thermal efficiency with reduced fuel consumption and exhaust emissions that are compatible with international standards. This paper reviews the efforts put by different researchers in modifying the engine components and systems to develop a diesel engine run on biodiesel for better performance, progressive combustion and improved emissions.

“…When 100 mM salt was added, the emulsions had the best stability [20]. Furthermore, the stability of fuel microemulsions has been investigated by Olsson et al [25,26], Dash et al [27,28] and Piskunov et al [29,30]. These investigations mainly focus on experimental analysis, which is not the mechanism that affects the factors of emulsion formation and stability.…”

The dissipative particle dynamics simulation method is adopted to investigate the microemulsion systems prepared with surfactant (H1T1), oil (O) and water (W), which are expressed by coarse-grained models. Two topologies of O/W and W/O microemulsions are simulated with various oil and water ratios. Inverse W/O microemulsion transform to O/W microemulsion by decreasing the ratio of oil-water from 3:1 to 1:3. The stability of O/W and W/O microemulsion is controlled by shear rate, inorganic salt and the temperature, and the corresponding results are analyzed by the translucent three-dimensional structure, the mean interfacial tension and end-to-end distance of H1T1. The results show that W/O microemulsion is more stable than O/W microemulsion to resist higher inorganic salt concentration, shear rate and temperature. This investigation provides a powerful tool to predict the structure and the stability of various microemulsion systems, which is of great importance to developing new multifunctional microemulsions for multiple applications.

“…The experimental methods and some raw data on temperature-dependent stability , and quantitative estimations of secondary atomization are partly taken from our earlier studies considering the mentioned fuel microemulsion characteristics independently. Using the well-known method of multiple-criteria decision analysis, − this study is an attempt to find out and confirm the combined influence of the characteristics of fuel microemulsions interrelated according to the known interdisciplinary research ,, in fluid dynamics (drop spreading and breakup on a solid surface), colloid science (stability of dispersed systems), and rheology (viscosity) on the impact of the single-phase and compound multi-phase drops on a solid surface.…”

The utilization of fuel microemulsions helps in reducing harmful emissions, enhancing combustion efficiency, and preserving conventional fuels. This study is focused on the effect of the properties and phase behavior of water-in-diesel and water-in-biodiesel microemulsions that can be used as an alternative fuel on the droplet impingement dynamics of such fluids on a heated wall in the film boiling regime. The microemulsions represent complex fluids consisting of diesel fuel–rapeseed oil blends and distilled water with different mixture volume ratios. The emulsification is carried out using a mixture of a surfactant [isononylphenol poly(ethylene glycol) ether, PEG-6] and a co-surfactant (2-ethylhexanol) with a volume ratio of 9/1. The study considers the efficiency of the fuel samples in terms of the temperature-dependent viscosity and aggregate thermal stability as well as the quantitative characteristics of the spreading drop breakup, namely, mean diameter and number of ejected droplets. The fuel efficiency factor is derived to reveal the optimal samples. We test the phase behavior of the water–diesel fuel/rapeseed oil–PEG-6/2-ethylhexanol system in a wide temperature range. Comprehensive viscosity tests are carried out within the temperature ranges of stability to check the viscosity values of the developed microemulsions against the viscosity of the conventional diesel fuels.
