Combustion, Performance and Emission Analysis of Diesel Engine Fuelled with Methyl Esters of Fish oil

International Journal of Science and Technology 01/2011; 1.

ABSTRACT The methyl esters of vegetable oils, known as biodiesel are becoming increasingly popular because of their low environmental impact and potential as a green alternative fuel for diesel engine and they would not require significant modification of existing engine hardware. Methyl ester of Fish oil (FME) is derived through transesterification process. Experimental investigations have been carried out to examine properties, performance and emissions of different blends (B00, B20, B40, B60, B80, and B100) of FME comparison to diesel. A Computer assisted Single cylinder constant speed water cooled four stroke direct diesel engine (5 H.P) which is commonly used in the agricultural sector for driving the pumps and small electrical generators is selected for the experimental investigation. The performance, emissions and combustion characteristics are analyzed. The combustion parameters considered for this analysis are cylinder pressure and rate of heat release. The brake thermal efficiency is slightly reduced and hydrocarbon, carbon monoxide and smoke emissions in the exhaust are reduced when fueled with methyl esters compared to diesel. But the NOx emissions are high when fueled with methyl esters compared to diesel.

    ABSTRACT: Bio-diesel manufactured from vegetable oils, animal fats and used cooking oils is an alternative fuel for diesel engines. It offers many advantages such as renewable, energy efficient, nontoxic, sulfur free and bio-degradable, and also offers cleaner combustion and reduces global warming gas emissions. Experiments are conducted by fuelling the diesel engine with bio-diesel with LPG blends. The engine is properly modified to operate under dual fuel operation using LPG as the mixed fuel along with Diesel and TME as ignition source. The brake thermal efficiency of TME with LPG (2LPM) blend is increased at an average of 5%.HC emissions of TME with LPG (2LPM) blend is reduced by about at an average 21%. CO emissions of TME with LPG (2LPM) blends are reduced at an average of 33.6%. NOx emissions of TME with LPG (2LPM) blend are reduced at an average of 4.4%. Smoke Opacity of TME with LPG (2LPM) blend is reduced at an average of 10%. Keywords biodiesel, diesel engine, alternate fuels, tallow oil and methyl esters of tallow oil, LPG.
