Effect of DEE Injection in Pongamia Pinnata Biodiesel Fulled CI Engine Using Hydrogen as Secondary Fuel

Abstract:

In advancing modern world, the recent technological advancements especially in the field of automobile and industrial sectors have created a hike in energy demand. The fossil fuels, which are the main sources of energy, are non-renewable. Due to excessive exploitation, the fossil fuels are depleting rapidly and have created a need for alternate fuel. The researches have been conducted on various biodiesel worldwide to acquire an efficient biodiesel. The biodiesel of pongamia pinnata is one such feasible alternative since the tropical climatic conditions of Asia supports its large cultivation. This paper investigates the characteristics of engine fuelled by pongamia pinnata biodiesel. The use of biodiesel as primary fuel causes reduction in the engine performance. The performance of biodiesel fuelled engine is improved by the induction of hydrogen into air intake manifold. The induction of hydrogen increases the brake thermal efficiency by 3.41%. The hydrogen induction increases NO_X in the exhaust. In order to reduce the NO_X emission, Diethyl ether is injected in to the engine at constant rate of 0.7 gm/min. The DEE injection reduces the NO_X and also increases the engine performance to a significant level.
