In the present scenario owing to the depletion of fossil fuel and at the same time increase in demand averts the researchers towards the alternative fuel. Various investigation are being carried out to find the most suitable alternate for the fossil fuel in IC engine, which satisfies the demand, improves the performance and decreases the emission. This paper deals with the multi fuel mode. Tests were performed at 4S mono cylinder dual fuel diesel engine with blends of acetylene in different proportions (0.199 kg/hr., 0.394 kg/hr. and 0.588 kg/hr.) with 20% waste cooking oil at a rated injection pressure of 200bar.The result shows the increased in BTE and deceased BSFC and exhaust gas temperature, furtherance the decrease in NOx and CO are observed as the amount of acetylene increases. BTE increases due to the lower auto ignition temperature and high calorific value of acetylene. Graphs were obtained based on the performance of the engine and B20 with 0.394 kg/hr. of acetylene is concluded to be optimum, B20 with 0.199 kg/hr. of acetylene shows the result similar to diesel operation, at B20 with 0.588 kg/hr. of acetylene increase in the knocking effect was observed.
