“…Therefore, EGR, although effective to reduce NO x , further increases the smoke and PM emissions [1]. Engine operation with oxygenated fuel and EGR results in NO x reductions without deteriorating brake specific fuel consumption (BSFC) and emissions [5,19].…”

“…However, in most cases [9][10][11], the NO x emission was reported to be higher than petroleum diesel (PD) because of the high O 2 content in biodiesel. Adding water to biodiesel fuel was an effective method for reducing NO x associated with biodiesel [12][13][14].…”

The Influence of Emulsified Water Fuel Containing Fresh Water Microalgae on Diesel Engine Performance, Combustion, Vibration and Emission

Microalgae is considered as an excellent potential renewable source of fuel in many forms including powder or slurry. A high percentage of emulsified water in the fuel is reported to reduce diesel engines’ emissions such as NOx, but that will compromise the engine output power. Using microalgae powder as an additive to enhance the emulsified water fuel heating value is the main objective of this work. Diesel engine combustion, vibration, performance and emissions were evaluated for pure cottonseed biodiesel (CS-B100), emulsified water 20% (vol.) in cottonseed biodiesel (CSB-E20) and emulsified water 20% (vol.) containing Fresh Water Microalgae Chlorella Vulgaris (FWM-CV) in cottonseed biodiesel (CSB-ME20). The emulsified water fuels showed a reduction in in-cylinder pressure, vibration, brake power, torque, exhaust gas temperature, CO2 and NOx, while BSFC and O2 were higher than the pure biodiesel (CS-B100). CSB-ME20 produced higher power and torque than CSB-E20 due to the presence of microalgae in the fuel that increased the energy content of the fuel.

“…Biodiesel is prepared from the seed oil of Thevetia Peruviana plant called yellow oleander. Emulsified biodiesel improved the trade-off relation between NO x concentration and smoke density over that of diesel emulsion [11]. However the emulsification stability of O/W/O biodiesel emulsion is inferior to that of the O/W/O diesel emulsion if the same surfactant mixture of span 80 (sorbitan monooleate) and tween 80 (polyoxyethylene sorbitan monooleate) is used [12].…”

Biodiesel is a promising renewable alternative fuel for diesel. However, its adaptability is limited by its emission levels surpassing the existing emission norms. In this situation, it is essential to search for an economically apt way of reducing the pollutants so as to make biodiesel a viable proposition. Emulsified fuels have more priority in reducing Nitrogen Oxide (NOx) and smoke simultaneously than other fuels. In this study, Thevetia Peruviana biodiesel was emulsified with water in the ratios of 5%, 10%, 15% and 20% to investigate the engine performance and emission characteristics. Emulsified fuels showed an improvement in brake thermal efficiency accompanied by the drastic reduction in NOx. From the detailed study it was found that 15% water emulsified fuel showed the best performance and less emission than the other combinations
