Abstract

Bio-fuels are the most energy efficient and environmental friendly viable options in the back drop of burning scarcity coupled with spiraling prices of conventional oils. Given the volume of diesel burning vehicles, it is the high time we replaced this conventional fuel either on partial or full scale, in the coming years. Given the fact that little or no modification is needed in the engine design or running conditions, bio-diesel is a potential candidate to accomplish this task. It is a renewable diesel substitute obtained by combining chemically any natural oil or fat with alcohol. Many traditional oil seeds like Pongamia, Neem, Jatropha, Rubber seed, Peanut, Cotton seed, Rape seed, Simarouba and Mahua etc. which are available abundantly in India and have been used for biodiesel production purpose. Many vegetable oils, animal fats and recycled cooking greases can also be transformed into biodiesel. This paper is an outcome of experimental runs using Simarouba, Mahua and Fish Oil, at different blends, and using different running conditions, with a fixed compression ratio of 17.5:1. The main objective is to replace the conventional Diesel partially using Cotton seed –Mahua oil(CSM) and Fishery biodiesel (FO). Testing was done using a single cylinder CI engine using blending with diesel in various blending ratios (B10 to B30). Engine performance parameters viz., brake specific fuel consumption, total fuel consumption, brake power, brake thermal efficiency, exhaust gas temperature were measured to evaluate and compare the behavior of diesel engine running on biodiesel at normal injection timing and pressure with a fixed compression ratio of 17.5:1. Performance study revealed that lower blend is superior to or on par with diesel, in both the bio-diesel blend combinations and could be a substitute for diesel.
