GDI engines commercially existed with spray guided mode where the fuel injector placed almost vertically and sprayed fuel is occupied throughout the volume of combustion chamber. With the advanced emission norms, NOx and Soot emissions control is the major task along with lower fuel consumption. To achieve the advanced emission norms, further modi cations are required before or during combustion.Combined air-wall guided mode combustion chamber modi cation is the advanced stage required for further improvement in mixing and superior combustion. Air-wall combined mode involved piston crown shape modi cation so that the modi ed shape should impart turbulence effects and divert the fuel/mixture ow towards the spark plug tip to initiate the combustion process. In this study, the combined air-wall guided mode gasoline direct injection engine was tested with gasoline blends using Ethanol, Methanol and N-Butanol at 20, 35 and 50% proportions under speci c xed conditions: 1500 rpm speed, 10% EGR and FIP of 150 bars with three split injections at 320˚, 220˚ and 100˚ before TDC. Tests were conducted over these gasoline blend proportions for engine performance and emission characteristics and achieved bene cial results with E20 gasoline blend over the entire applied torque values.

Vertical axis wind turbine is one of the types of savonius wind turbine; VAWT generates huge twisting moment when running under lower speed by wind. Savonius wind turbine is the self-starting turbine; it uses magnetic levitation principle to get high rotational speed for the Generator. Magnetic Levitation is the phenomenon in which anything can freely suspend in the air without any support with opposed of gravitational energy. This magnetic levitation occurred due to the repulsion between the two symmetrical poles. The strong levitation is occurred with the use of permanent magnets. This type of model is to show its greater efficiency in varying wind conditions as compared to the conventional horizontal axis wind turbine and contribute to steady growing popularity for the purpose of increased utilization in the recent future as a reliable source of power generation.

GDI engines commercially existed with spray guided mode where the fuel injector placed almost vertically and sprayed fuel is occupied throughout the volume of combustion chamber. With the advanced emission norms, NOx and Soot emissions control is the major task along with lower fuel consumption. To achieve the advanced emission norms, further modifications are required before or during combustion. Combined air-wall guided mode combustion chamber modification is the advanced stage required for further improvement in mixing and superior combustion. Air-wall combined mode involved piston crown shape modification so that the modified shape should impart turbulence effects and divert the fuel/mixture flow towards the spark plug tip to initiate the combustion process. In this study, the combined air-wall guided mode gasoline direct injection engine was tested with gasoline blends using Ethanol, Methanol and N-Butanol at 20, 35 and 50% proportions under specific fixed conditions: 1500 rpm speed, 10% EGR and FIP of 150 bars with three split injections at 320˚, 220˚ and 100˚ before TDC. Tests were conducted over these gasoline blend proportions for engine performance and emission characteristics and achieved beneficial results with E20 gasoline blend over the entire applied torque values.
