Performance Analysis of Diesel Engine using Biodiesel with the Influence of Dimethyl Ether Blend

Mono esters and Dimethyl ether are the two different promising alternative fuels for CI engine. In this study, the various ratios of Di Methyl Ether (DME) blended with 20% Calophyllum Inophyllum Methyl Ester (CIME20) blends have been examined on working characteristics of diesel engine under various loads. In this work, the DME is mixed with different ratios like 10% and 15% (vol. %) with 20% CIME blend. The experimental results indicate that DME improve the brake thermal efficiency (BTE) and decrease nitrogen oxide (NO), carbon monoxide (CO), and smoke emissions, while hydrocarbon (HC) and brake-specific fuel consumption (BSFC) emissions are increased. It is concluded that the 15% of DME blend with CIME20 gave the improvement in performance and decrease the gas emissions of the engine that is utilized partially to replace the diesel usage in diesel engine.
