Comparative Analysis of Biodiesel as a Additive with Pure Diesel in Single Cylinder Four Stroke Diesel Engine Processes

Abstract

At present, the demand of energy resources is increasing while their stocks are decreasing with high rate. Bio-diesel is an energy source which is renewable and would help in controlling the demand and supply of fuel but also in the reduction of pollution. Bio-diesel is simple to use and easy to transport. Different ratios of bio-diesel and diesel were mixed to prepare blends which showed viscosity, heat content, density, efficiency closer to diesel. The performance of various blends was tested on four stroke single cylinder compression ignition engine. Testing showed that partial substitution of diesel by bio-diesel can result in increase performance of engine. The results conclude that bio-diesel would be a better alternative to diesel in coming days.In this investigation we were planed to investigate fuel consumption, power in different loading condition, break specific fuel consumption, break mean effective pressure from bio-diesel (Blend of 5% Growdiesel + HSD, 2% Growdiesel + HSD,1% Growdiesel +HSD, .5% Growdiesel +HSD) with HSD. Planed to take 10 hr trials in cache combination and comparison of data and valuable findings related cost. The results that the performance of high percentage blends and pure bio-diesel doesn’t fit the engine due to their viscosity and low thermal efficiency.
