Experimental Investigation of Performance, Emission and Combustion Characteristics on CI Engine Using Karanja Biodiesel with Acetylene (Welding Gas) Blend

In the present study the concept of using acetylene gas like other gases used with biodiesel blend in various investigations. In a dual fuel mode acetylene was used as an alternative fuel blended with karanja oil methyl ester (KOME) and its performance in a compression ignition engine was investigated. Experimental investigation has been carried out on a single cylinder, direct injection, and compression ignition engine run on dual fuel mode with diesel is injected as primary fuel and acetylene inducted as secondary gaseous fuel to obtain data on engine performance with different flow rates of pressure at 0.5kg/cm2, 0.8kg/cm2 is drawn to intake air manifold. In Dual fuel operation at 0.5kg/cm2 flow rate of acetylene thermal efficiency obtained is nearer when compared to neat diesel operation in the internal combustion engine such that it reduces the demand of the petroleum products that is going to be extinct in near future. It includes about the emissions of harmful gases that can be reduced by the use of acetylene instead of petroleum products. Due to the increasing demand for fossil fuels and environmental threat, a number of renewable sources of energy have been studied worldwide. The performance, combustion and emission characteristics of the diesel were evaluated and compared with dual fuel operation (KOME + Acetylene) at compression ratio 17.5:1. Based on the performance, combustion and emission parameters the flow rate of induction was optimized which were 0.5kg/cm2. The acetylene blend reduces in CO & HC emissions compared to diesel.
