Abstract

The study of effects of compression ratio (CR) in a diesel engine fuelled with ethanol–diesel blends and diesel is important as they significantly affect its performance and emissions. The present paper focuses on the experimental investigation of the influence of CR of the engine on the performance and emission characteristics of ethanol–diesel blended fuel and the results compared with diesel. Tests were carried out using three different compression ratios (CR 16.5:1, 14.3:1 and 12.6:1) at 40 and 60 % of maximum engine load. At lower CR the carbon monoxide (CO), carbon dioxide (CO2), hydro carbon emission (HC) increases and nitrogen oxides emissions (NOX) decreases. At higher CR the brake thermal efficiency (BTE) increases. It has been observed that the increase in BTE and brake specific fuel consumption (BSFC) was obtained with the increase of ethanol blend proportions with diesel. The emissions of NOX and CO2 decreases and the emission of CO and HC increases with increase of ethanol blend proportions with diesel.
