Analysis of Combustion and Emission Characteristics of SI Engine Powered with Diethyl Ether Blended Petrol as Fuel

Incomplete burning of the fuel and high emission in the engine were the major problems in using the petrol as a fuel. In this Experimental study, the effects of Diethyl Ether, petrol fuel blend investigated on four stroke four cylinder SI engine for analyzing the performance and combustion characteristics. The tests were performed while running the engine at speeds of 1500&1000 rpm and at four different engine load conditions (0, 3, 6, 9 kW). The results obtained from the use of Diethyl Ether, petrol fuel blends are compared to those of sole petrol in SI engine. The results indicated that when Diethyl Ether, petrol fuel blends were used, the Brake Specific Fuel Consumption and exhaust emission are decreased. Exhaust gases namely, carbon dioxide, carbon monoxide and total unburned hydrocarbons are measured using AVL exhaust gas analyzer. Performance and exhausts emissions are compared with sole petrol, using Diethyl Ether, petrol fuel blends. This oxygenates shows significant improvement for exhaust emission and also fuel consumptions at different load conditions. Citation: G.Satheeshkumar, PANNAI COLLEGE OF ENGINEERING AND TECHNOLOGY.
