Abstract Stringent emission norms and environment degradation due to pollutants from the automotive vehicles lead us to find the suitable alternative for petrol and diesel. Oxygenates reduce the emissions of carbon monoxide and hydrocarbons by improving the combustion of the fuel. This study investigates the effects of two oxygenates (DIPE& MTBE) blended gasoline on a multi – cylinder Spark Ignition (SI) Engine. Locally produced gasoline was blended with five different Percentages of DIPE and MTBE namely 10%, 20%, 30%, 40%, 50%. These blends were tested for its properties for using in the engine. The performance and emission tests were conducted on a multi – cylinder SI Engine coupled with an eddy current dynamometer. The emissions were measured using an exhaust gas analyzer. The experimental results proved that the 20% blend of both DIPE and MTBE shows decrease in specific fuel consumption and increase in brake thermal efficiency more than a sole fuel. The emission tests found that the CO and HC have reduced to great extent, while NOx appreciably decreased. The addition of oxygenates with the Gasoline enhanced the performance with reduced emissions and hope to be a good alternative fuel.
