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.

This study focused on the computational and parametric research on a single cylinder spark ignition engine using dual-fuel, 100 % gasoline and (10 %, 20 %, 30 %) propane in gasoline on volume basis as an alternative fuel for investigating the performance and emission characteristics of spark ignition engine. The performance parameters Brake power, Torque, Bsfc, and Bmep were examined using Avl Boost software. In addition, the exhaust emissions like nitrogen oxide, carbon monoxide, hydrocarbons were also measured. The (10 %, 20 %, &30 %) of propane in gasoline decreases in power compared to 100 % gasoline, however engine fuelled with 10 %, 20 %, and 30 % propane in gasoline shows reduction in specific fuel consumption. The study investigates the effect of dual-fuel propane and gasoline on a fourstroke single cylinder spark ignition engine. The study was carried out at varying percentage load and varying compression ratio for constant engine speed. The focus of this parametric study tries to investigate the effects of replacing individual gasoline and propane with the optimum mixture of 10 %, 20 %, and 30 % propane in gasoline on volume basis in spark ignition engine in order to improve its performance and emission characteristics.
