Commercially existing GDI engines were normally with spray guided mode where the fuel injector placed almost vertically and sprayed fuel is occupied throughout the volume of combustion chamber. In order to achieve the advanced emission norms, further modifications are required with the existing one. With the advanced emission norms, NOx and PM emissions control is the major task along with lower fuel consumption. In this study, gasoline blends with Ethanol, Methanol, N-Butanol and DMF were used 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.
