EXPERIMENTAL INVESTIGATION ON USE OF CNG AND HONGE BIODIESEL IN A SINGLE CYLINDER DIESEL ENGINE

Drastic crises in the demand of energy made engineers to focus on different energy sources mainly to balance the lack of petroleum products by replacing the diesel with liquid and gaseous fuels as an alternate fuel. The objective of the present work is to evaluate compressed natural gas (CNG) and honge oil methyl ester (HOME) as a dual fuel mode in a compression ignition diesel engine. The experiment is carried out for pure diesel, neat honge biodiesel and HOME with constant CNG supply at rate of 0.29 kg/hr and 0.5 kg/hr respectively and it is observed that the brake thermal efficiency for 0.5 kg/hr CNG-HOME is 26.4% against 28.4% diesel at 75% of the load. The exhaust gas analysis showed CO and HC are higher at low load and gradually decreased with increase in the brake power for CNG flow rate of 0.29 kg/hr and 0.5 kg/hr with HOME. Engine operation in the dual fuel mode has lower NOx emission and lower smoke compared to diesel and neat biodiesel. In dual fuel mode NOx emission and smoke is lower for 0.5 kg/hr CNG flow rate which is optimum in the cases presented here, with a very little reduction in thermal efficiency.
