Experimental Performance Analysis of Acetylene Aspirated Diesel Engine

A several studies and research has been carried out in enhancing the performance of diesel engine but the human effort is still ineffective in this challenge, in this project work an acetylene is used as alternate fuel due to its very wide flammability range and minimum ignition energy is required for ignition since the engine can run in lean mode with higher specific heat ratios leading to increased thermal efficiency. It has higher flame speed and hence faster energy release And at stoichiometeric mixtures, acetylene engines could closely approach thermodynamically ideal engine cycle. performance 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 0.5bar, 0.8bar is drawn to intake air manifold. From results obtained the thermal efficiency is nearer to diesel and energy consumption are less than the diesel at full load for the flow rate of 0.5bar.
