Study of Performance Characteristics of Single Cylinder Diesel Engine Using Water Emulsified Diesel as Fuel

In this research paper the effect of water in diesel emulsion on performance characteristics of diesel engine has been studied. Various combination of water in diesel emulsion that is 5 % water denoted as W5, 10 % water denoted as W10, 20 % water denoted as W20 and 30 % water denoted as W30 are used in the experiment carried out to find the emulsion which gives best performance characteristics for diesel engine. Best performance characteristics of diesel engine here stands for high brake thermal efficiency, high torque, higher brake power and low brake specific fuel consumption. Thus test was carried out first using pure diesel and then W5, W10, W20 and W30 respectively and the readings were noted down in observation tables and graphs were drawn and conclusion was arrived by carefully analysing the graphs. By using water in diesel emulsion the peak temperature in the combustion chamber is lowered which gives many advantages like low emissions from the engine.
