Comparison of Performance of Diesel and LPG Blends in Dual Fuel Engine with Tallow Methyl Ester (TME) as a Fuel

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
