“…Augmented regulations on particulate matter and NOx, and also issues raised on greenhouse gas emission like CO2 are the reasons for demanding research work on bio-fuels all over the world [3][4][5][6]. Biodiesel derived from the trans-esterification of fats and oils [7][8][9][10][11] is a possible fuel for diesel engines. The properties of this fuel is comparable to that of diesel and can be used directly to run existing diesel engines or as a blend with crude oil diesel [12].…”

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.

“…Further, the increase in CO is observed at maximum load condition. This is due to decrease in combustion temperature which leads to partial oxidation of CO to CO2 conversion process [27,29]. It is observed that when the load increased from 10% to 75 % the CO emissions are decreased for 3% DEE and 6% DEE blends respectively.…”

In this study the performance and emission characteristics of spark ignition genset engine fueled with gasoline and diethyl ether (DEE) blends are carried out. The DEE blends are varied from 3%, 6% and 9% by volume in gasoline. A four-stroke single cylinder constant speed spark ignition engine is used for the experiments. The variation in fuel consumption and exhaust emission with respect to two different inlet air temperatures are studied. The concentration of exhaust emissions such as HC, CO, NOx is observed. The parameters such as inlet air temperature, brake specific fuel consumption, relative air to fuel ratio are also measured. It is noticed that 6% DEE blend in gasoline reduced almost reduced HC emission about 57% and also considerable reduction in CO emission at lower air intake temperature. The addition of diethyl ether has an improvement in performance and significant reduction in HC, CO and NOx emissions.

“…The primary aims of using spark ignition (SI) engine fuels are to improve the fuel characteristics in terms of reduced consumption of engine fuel, enhanced engine power and minimised redundant emissions [3,4]. Over the years, significant advancements have been made in SI engines [5][6][7]. SI engines have been adapted for three-way catalysts with advanced engine designs and improved fuel properties.…”

“…Knop, Loos [25] considered a ternary mixture of n-heptane, toluene and isooctane to evaluate a linear-by-mole blending rule. Babu, Rao [26] determined the effect on the emission and performance of a gasoline engine of injecting a water mist into an intake manifold through a nozzle at the throttle body. It was found that the performance and volumetric efficiency of the engine were increased by up to 10%.…”

The resistance of gasoline to knocking is critically determined by the octane number. The engine will encounter a significant waste of power, reduced efficiency and enhanced emission levels if a well-defined gasoline octane number is not employed. In this study, the engine performance and emission of hazardous gases were experimentally investigated through the use of three gasoline fuels (RON95, 97 and 102). The engine selected for the testing was a 1.6-L four-cylinder Toyota 4A-GE Blacktop VVT with the original ECU. The engine was run at different constants for various part load conditions as well as at constant throttle body. The engine that was operated with RON97 fuel was found to display positive improvements in terms of the brake specific fuel consumption of the engine, reduced at an average of 5 and 10%, compared to RON102 and RON95 fuels, respectively. Furthermore, the engine operated with RON102 fuel exhibited higher torque and engine power compared to RON97 and RON95. The brake thermal efficiency for both RON97 and RON102 fuels was remarkably improved at an average of 12% compared to RON95. The incorporation of RON102 fuel reduced the emission of NOX compared to RON95 and RON97 fuels at an average of 34% and 40%, respectively. The RON102 fuel produced the highest HC emission compared to RON97 and RON95. The CO emission was found to be higher for RON102 fuel compared to RON97 and RON95 at an average of 12.4% and 17%, respectively. The study concluded that although engine performance and efficiency versus gasoline depend highly on the engine design parameters, RON97 is able to deliver high performance and efficiency in all conditions. Therefore, it is recommended that RON97 be used instead of RON95 to achieve better performance with this type of engine.
