ACKNOWLEDGEMENT

This final year project was the result of the thought process combined with hard work of not just us, but a group of other people. This thesis would be incomplete without expressing my heartfelt gratitude to them. We profoundly express our thanks to The Head of Department of Automobile Engineering, Dr. LEENUS J. MARTIN for his guidance and his encouragement. We thank our guide Dr. B NAGALINGAM in extending his support for the project. We would like to thank Mr. G ANARBASU our Prof. School of Mechanical Engineering and for guiding and helping us whole-heartedly in completing our project. We would also like to express our sincere thanks to all our faculty members and nonteaching staff members of our department and our friends for their invaluable and their kind help throughout this work. We would also like to thank PLACKA FLOWMETERS, ETA LAB, AUM NEEM OIL MANUFACTURERS and few automobile mechanics for their support and helping us with component development.

ABSTRACT

The main objective of this project is to develop LIQUIFIED PETROLEUM GAS induction system. We have to study the performance of diesel engine working on Neem oil bio diesel by inducting known quantity of LPG using a carburetor controlled induction system.The emission from diesel engine will be reduced, andthe performance of the engine working on biodiesel is to be compared with diesel. The experimental study has been carried out in a single cylinder diesel engine. The experimental set-up is such that known quantity of LPG is inducted in the intake manifold using a detailed setup involving pressure regulator, flow meter, vaporizer, wet type flame arrestor, and a modified carburetor. Results of the experimental study of a dual fuel operated diesel engine are presented, which show the influence of partial premixing fumigation of LPG with intake airon the exhaust emissions and the engine performance parameters. The result shows that the brake thermal efficiency reduces by 8.01 % when biodiesel is used as compared to diesel at peak load condition. It increases by 8.29 % in comparison to biodiesel when 20 % of LPG is inducted at peak load. At peak load, there is a drastic reduction in the emission of NOx when biodiesel is used as compared to diesel. The emission reduces further when 20 % of LPG is inducted. Similar is the condition with other emission gases like CO, and CO2.
