“…As a result, once a choked flow phenomenon occurred, the volumetric efficiency will significantly decrease and the power will also decrease [21]. The experimental result of the engine speed at maximum engine power agreed with the investigation observed by Phuangwongtrakul [4]. However, the relationship between power and ethanol percentage in the fuel showed a different tendency with a previous research by [10].…”

The depletion of fossil fuel availability and increase of pollution due to the use of fossil fuels have forced the researcher to find a renewable-friendly energy source. One of the potential replacements is alcohol based fuel. This present study investigated experimentally the influence of ethanol addition on the engine performance, in terms of effective power, brake specific fuel consumption, and exhaust emissions of a gasoline spark ignition engine. The engine used in the research was a 4-stroke single cylinder, indirect injection system with engine capacity of 124.8cc, and compression ratio of 9.3:1. The experiments were conducted at eight different engine speeds ranging from 1500 rpm to 5000 rpm and 10 types of gasoline-ethanol mixtures (E10 to E100). The result showed that the effective power decreased with the increase of ethanol in the fuel blends for all variations of engine speed. Leaning effect of ethanol addition in the blend fuel caused the CO emissions to decrease greatly as well as the HC emissions. On average, gasoline engine fueled by pure ethanol reduced the CO emission level by more than 60 % in volume compared to the engine with gasoline fuel. On average, the maximum power of the engine with fuel blend was obtained at engine speed of around 2500 to 3000 rpm. For higher ethanol content on the fuel blend, the optimum shift to the lower engine speed. It can be concluded that engine operation with ethanol content on the fuel performed better in the lower engine speed.

“…Furthermore, burning ethanol is cleaner than fossil fuels so as to reduce environmental pollution and greenhouse emissions. Currently, alcohol based fuel is found to be the main focus for internal combustion engine research [1][2][3][4][5][6][7][8]. Ethanol could be used as a blending fuel in gasoline and diesel engines [9][10][11].…”

“…As mechanical efficiency is directly proportional to the brake power of the engine, which is highest for gasoline as the fuel as compared to other alternative fuels so mechanical efficiency shows slight increase in efficiency. Mechanical efficiency is defined as the ratio of brake power and indicated power [27]. Almost all the fuel shows similar kind of trend i.e.…”

In this contribution the two alternative fuels, firstly blended fuel of ethanol and gasoline (i.e. E15%+Gasoline 85%), and secondly, micro-emulsion (i.e. Gasoline 90%, E8% and H2O 2%) were compared with conventional 100% Gasoline fuel for checking the performance, combustion, and emission characteristics of 3-Cylinder SI engine experimentally. The blended fuel containing 15% ethanol with 85% gasoline and the micro-emulsion based fuel which contains H2O molecule in addition to simple blending were prepared in the lab, and both the fuels were tested experimentally on a 3-cylinder SI engine based test rig in order to find out which alternative fuel is more efficient in terms of performance and emission characteristics. The results depicted that although both the micro-emulsion based fuel and the blended fuel showed reduction in power as compared to conventional 100% Gasoline fuel, but the emissions were least for the micro-emulsion based fuel followed by the blended fuel. The CO, HC, and NOx emission decreased for both ethanol blended gasoline fuel and the micro-emulsion based fuel as compared to the 100% Gasoline. The injected water in the micro-emulsion fuel reduces the temperature inside the combustion chamber which is responsible for this decrease in NOx emission. For combustion analysis, pressure v/s the crank-angle showed slight decrease for the blended fuel (i.e. 15% ethanol with 85% Gasoline) and the micro-emulsion based fuel (i.e. Gasoline 90%, E8% and H2O 2%) as compared to the conventional 100% gasoline fuel. This can again be attributed to the fact that the micro-emulsion based fuel has a lower combustion chamber temperature compared to the conventional 100% Gasoline.
