Abstract:

Environmental concerns and fluctuating fossil fuel prices necessitate a shift toward cleaner energy sources. Diesel engines, prevalent in industry and transportation, face stringent emission regulations. This study evaluates the performance and emissions of a CI engine using ternary fuel blends of diesel, diethyl ether, and ethanol in varying ratios: D-DEE5-E5, D-DEE5-E10, and D-DEE5-E15. The D-DEE5-E10 blend demonstrated optimal results, achieving the lowest brake-specific fuel consumption (0.245 kg/kWh) and highest brake thermal efficiency (39.83%). The improved cetane number of DEE and the oxygen availability in ethanol enhanced combustion, significantly reducing smoke (6.8%), hydrocarbons (18 ppm), and carbon monoxide (0.12% vol.). However, the elevated combustion temperatures led to increased nitrogen oxide emissions. Overall, the D-DEE5-E10 blend emerges as a promising cleaner alternative to conventional diesel, effectively balancing improved performance with reduced emissions.
