“…This may be due to the oxygen content in methyl esters, which improved combustion [44]. Also, poor fuel atomization and vaporization due to higher viscosity of methyl esters and their blends resulted in late burning of the injected fuel and higher exhaust gas temperature [45]. Figure 6 shows the variation of HC emission with brake power.…”

In this work, biodiesel obtained from the transesterfication of Jatropha seeds and Fish wastes is used as an alternative fuel to diesel in stationary single cylinder diesel engines. The biodiesel obtained has good ignition ability due to its relatively high cetane number compared to that of conventional diesel fuel. The performance, combustion and emission tests using Jatropha Oil Methyl Ester (JOME), Fish Oil Methyl Ester (FOME) and their blends (20% JOME and 20% FOME) with diesel were carried out at constant speed and variable loads condition. The results showed that both blends could be used as fuels for diesel engine without any major modification on the engine. Carbon monoxide (CO), UBHC and smoke emissions were observed to be lesser at all loads for both the blends compared to diesel fuel, while NOx emission was slightly higher. JOME blend was found to be better than FOME blend.

“…CO emission resulted from the lack of oxygen during combustion. Methyl esters with higher oxygen content produced efficient and effective combustion [48] and higher cetane index [45], leading to lower CO emission. Lower carbon to hydrogen ratio of methyl esters also results in lower CO emission.…”

“…In many cases they are preferable due to their high thermal efficiency, and low regulated emissions of unburned hydrocarbons (HC), carbon monoxide (CO) and carbon dioxide (CO 2 ) compared to those of spark ignition engines [1,2]. The other important advantage of diesel engines is that they can operate at higher compression ratios, which permit them to use low energy-content alternative fuels such as biogas.…”

“…Mustafi and Raine [21] studied emissions from a dual fuel engine fuelled with NG and biogas; however, dual fuel combustion characteristics and their effects on emissions were not presented there. Recent efforts using biogas-biodiesel in dual fuel application are found in the references [22][23][24], or biogas application in HCCI engine [25]; where engine performance, combustion and emission characteristics are investigated. Although there are researches on the combustion and emission characteristics of biogas-diesel/biodiesel in dual-fuel concept, it is necessary to investigate into more detail the reduction characteristics of exhaust emissions and the combustion performance of the biogas-diesel dual-fuel engine in order to establish biogas as an alternative fuel for stationary older diesel engines.…”

Among the different efforts towards the reduction in pollutant emissions from direct injection (DI) diesel engines, the use of gaseous fuels as a partial supplement for diesel fuel has been proposed by many researchers. These engines are known as dual fuel engines. An experimental investigation was performed to investigate the influence of dual-fuel combustion on the performance and exhaust emissions of a DI diesel engine fueled with natural gas (NG) and biogas. In this work, the combustion pressure and the rate of heat release were evaluated experimentally in order to analyze the combustion characteristics and their effects on exhaust emissions including particulate matter (PM) for single-fuel (diesel) and dual fuel combustion modes. The use of NG as an alternative fuel is a promising solution.Biogas, on the other hand, is a renewable alternative fuel that has tremendous potential to be used in diesel engines especially in developing nations. Comparative results are presented revealing the effect of dual fuel combustion on engine performance and exhaust gaseous and PM emissions for the engine operating conditions considered in this study.

Internal combustion (IC) engines continue to maintain their position as principle prime mover for energy transformation especially in transportation and power sectors. Research on IC engines has many frontiers: optimum engine design to get better fuel utilization and mitigate spefici emissions; development of alternate fuels to reduce the dependence on fast depleting fossil fuels; use of oxygenated hydrocarbons in conventional compression ignition (CI) and spark ignition (SI) engines; development of reaction kinetics and thermal databases for different hydrocarbons to simulate combustion process in IC engines. This study reviews the status of the current research on all of the above mentioned frontiers. It lays down various parameters and their mutual dependencies and how they affect engine' performance and emissions characteristics. Various strategies that are employed to control these performance and emissions characteristics have been discussed. The application of different liquid (Alcohols and biofuels) and gaseous (natural gas and hydrogen) fuels as alternatives to the fossil fuels has been detailed. It also provides an insight into the development of various surrogates for gasoline and diesel fuels. Numerical modelling of the internal combustion engines and the application of emulsified nano‐fuels have also been discussed in detail.
