Review on Effect of Varying Compression Ratio on Performance & Emissions of Diesel Engine fueled with Bio-diesel

Abstract

Biodiesel have proven to be most promising of various alternate fuels used in diesel engine to reduced exhaust emissions maintaining the performance characteristics. The emission & performance characteristics are also affected by various working parameters like compression ratio, injection pressure and injection timing. Present paper deals with effect of variation in compression ratio on engine performance and emission. Paper deals with effects on engine fueled with diesel, blend of diesel with biodiesel and purely on biodiesel with a view to provide a platform for comparison of the parameter on various fuels. Effect on Brake Specific Fuel Consumption, Brake Thermal Efficiency, Smoke opacity, CO emissions and Exhaust Temperature have been studied and presented.
