Abstract

On the face of the upcoming energy crisis, vegetable oils have come up as a promising source of fuel. They are being studied widely because of their abundant availability, renewable nature and better performance when used in engines. Many vegetable oils have been investigated in compression ignition engine by fuel modification or engine modification. The vegetable oils have very high density and viscosity, so we have used the methyl ester of the oil to overcome these problems. Their use in form of methyl esters in non-modified engines has given encouraging results.Coconut oil (copra), Waste vegetable oil, Karanja oil (Pongamia Pinnata) is available abundantly in India. An experimental investigation was made to evaluate the performance characteristics and overall emissions of a diesel engine using different blends of these three methyl esters with mineral diesel. Methyl esters of these three oils were blended with diesel in proportions of 20% and 40% by mass and studied under various load conditions in a compression ignition (diesel) engine. The performance parameters were found to be very close to that of mineral diesel. The brake thermal efficiency and mechanical efficiency were better than mineral diesel for some specific blending ratios under certain loads. The emission characteristics were also studied and levels of carbon dioxide, carbon monoxide, nitric oxide and hydrocarbons were found to be higher than pure diesel. T. Pratheep Reddy | P.
