Experimental Analysis of Performance, Emission and Combustion Characteristics of Single Cylinder Diesel Engine by using Peanut Bio-Diesel and Acetylene Gas in Dual Fuel Mode

The main objective of project is to analyze the various parameters such as performance parameter, combustion parameter and emission parameter, experiment is conducted on 4-stroke single cylinder DI diesel engine at constant speed of 1500 rpm and at rated power of 5.2 kW, which is made to run on peanut bio diesel and acetylene gas in a dual fuel mode. Here acetylene gas is admitted along with air at different pressure both for diesel & peanut biodiesel and result are obtained. The result obtained is compared with diesel graphically. Result showed that brake thermal efficiency and brake specific fuel consumption of peanut biodiesel at 0.5 bar pressure of acetylene is found more closely to pure diesel and emission characteristics like HC is found lower then diesel and CO ,NOx slightly greater then diesel . Combustion characteristics like cylinder peak pressure for peanut biodiesel are found more then diesel baseline. Hence it shows peanut biodiesel with acetylene at pressure of 0.5 bar has similar outcome as diesel and may be used as supplement fuel which reduces the dependability on petroleum products.
