The effect of methanol addition (by blending) and methanol induction (by carburetion) on performance of a vegetable oil (Madhuca Indica called as Mahua oil) based diesel engine was studied experimentally. A single cylinder, water cooled, DI, diesel engine was used. Baseline data was generated with neat diesel and neat Mahua oil as fuels. Subsequently methanol was blended with Mahua oil in different proportions such as 5, 10, 15 and 20% by mass and tested for engine's performance. Finally the engine was operated in dual fuel mode of operation with methanol induction and Mahua oil injection. Engine performance, emission and combustion characteristics of ND (neat diesel), NMO (neat Mahua oil), MOMB (Mahua oil+15% methanol blend by mass) and MOMDFE (Mahua oil dual fuel engine at 15% mass share) were compared and analyzed at 100% and 40% loads. NMO resulted in inferior performance and increased emissions at both power outputs as compared to ND.
