“…This makes the need for environmentally friendly alternative fuels very crucial [3], [5]. Therefore, the researchers conducted many studies and found that bioethanol is one type of alternative fuel that can be applied to internal combustion engines (ICdisE) and at the same time to overcome the fuel energy crisis [4], [6], [7]. The raw material for bioethanol used in this study is sourced from coconut sap water which is processed through natural fermentation and fractional distillation [8], [9].…”

Experimental research has been conducted on the effect of ignition timings on the characteristics and performance of gasohol engines such as power, torque, specific fuel consumption, and thermal efficiency. The fuel used in this research is pure gasoline and a mixture of 50% bioethanol (BE50). The results show that the ignition timing that gives the maximum effect occurs at the top and bottom dead points of 9 degrees for gasoline and 12 degrees for BE50 fuel. Furthermore, the maximum power is obtained at 6,500 rpm, and at an ignition time of 12 degrees BTDC the maximum power generated is 4.63 hp, while for an ignition time of 9 degrees BTDC the power generated is 3.38 hp which occurs at 6500 rpm. These results indicate that there is an increase in power of 6.4%. Moreover, the results also show that for optimal gasoline conditions, the amount of energy consumed at an engine speed of 7000 rpm is around 15705.78 kcal/hour, and for BE-50 it is around 12582.03 kcal/hour, where there is a reduction of about 25.44 %. However, in general, it can be seen that during optimal ignition, there is a saving in fuel consumption in the gasoline-BE50 mixture, while at the same time producing a fairly large thermal efficiency. These results indicate that BE50 has the potential to be used as an alternative fuel in small gasoline engines.

“…Their results concluded that the addition of different heavy alcohols to gasoline, reduces the thermal efficiency and increases the fuel consumption. Sayin Kul and Ciniviz [8], investigated energy and exergy analyses by blending two different bioethanol with gasoline on an SI engine. They prepared their fuels by adding both bioethanol, one of them was produced from waste bread and the other from sugar beet.…”

Despite the increasing use of petroleum-based fuel as a result of ever-increasing energy demands, the search for alternative fuels remains important. In this study, in a Lombardini LGW 523 brand 2-cylinder 4-stroke water-cooled engine, different volumetric ratios of methanol and gasoline fuel mixtures (M10, M20, M30, M40) were used at 4 different torque values (5, 10, 15, 20 Nm) at a constant 3000 engine speed. It is discussed. As a result of the study, engine performance, emission and energy analysis examination was carried out experimentally. Keywords: Energy, exergy, internal combustion engine, methanol fuel

“…With the dwindling resources of crude oil and the increasing consumption of fuel in the transportation, industrial, and household sectors, as well as the increase in the global population, have resulted in an energy crisis [ [1] , [2] , [3] ]. This situation emphasizes the crucial solution for renewable fuels [ 4 ].…”
