  • Abstract:
  • this work investigates the effect of variable compression ratio on performance of a single cylinder four stroke diesel engines fuelled with diesel & oxygenated blending. Experiments were conducted with different compression ratios of 16,17and18 at various load conditions (0Kg to 9Kg) & at a constant speed of 1500 rpm. Diesel engine fueled with oxygenated additives blending of 2 Ethoxy Ethyl Acetate (EEA) & Dimethyl carbonate with diesel. First fuel blends which contain 5% (95% Diesel & 5% EEA), 10% (90% Diesel &10% EEA) and 15% (85% Diesel &15% EEA) of EEA additive & second fuel blend which contain 5% (95% Diesel & 5% DMC), 10% (90% Diesel & 10%DMC) and 15% (85% Diesel & 15% DMC) of DMC additive were prepared and the effect of these additives blends on performance of single cylinder variable compression engine. It was observed that increasing the Brake thermal efficiency at both additives blending in comparison with diesel. Brake thermal efficiency also increases with increasing compression ratio for diesel & all blends. Brake specific fuel consumption was found to be decreases at both additives blending in comparison with diesel. Brake specific fuel consumption also decreases with increasing compression ratio for diesel & all blends.
