PERFORMANCE EVALUATION OF A DIESEL ENGINE RUNNING IN DUAL FUEL MODE WITH KARANJA BIO DIESEL (KOME) & LIQUIFIED PETROLEUM GAS (LPG)

Present study shows utilisation of LPG in CI engine with Bio diesel in dual fuel mode. For this experimental work a stationary, single cylinder, four stroke diesel engine was used with few attachments. Major performance parameters such as Brake power, Brake thermal efficiency, Brake specific fuel consumption etc. were evaluated at different loads and with different fuel combinations . up to 12% biodiesel was saved in dual fuel mode & up to 40% improvements were evident in Brake specific fuel consumption, whereas break thermal efficiency did not improve due to poor utilization of high energy content of LPG. The cost incurred for making Biodiesel was huge and disappointing but if it is promoted by government and made on a large scale, it would definitely prove itself as an affordable fuel. The concept of present work of mixing biodiesel and LPG for operating diesel engine can be employed to make more technologically subtle & advance engines that could run smoothly on dual fuel and harness their full potential.
