Abstract
Biodiesels of simarouba, rubber seed and rice bran were produced from their respective feed stocks by transesterificationprocessandtestedinanairco oleddieselengineasasubstitutefuels.Theexpe rimentalinvestigationaims in accessibility of using neat biodiesels in anunmodified stationery diesel engine meant for agriculture and gen-set applications in India. Diesel and neat biodiesels of simarouba, rubber seed (non-edible oils) and rice bran (edibleoil) were used for conducting tests at varying load conditions (0, 25%, 50%, 75% and 100%). The performance (brakethermal efficiency, brake specific fuel consumption), exhaust emissions (CO, HC and smoke opacity) and combustionresults(cylinderpressureriseandh eatreleaserate)wereanalyzedandcomparedwi thdieseloperation.Theperformance of engine was dropped, peak cylinder pressure rise and heat release rate were reduced as compared toconventional diesel. On the other hand the engine showed significant reductions of exhaust emissions(except NOx)while running with neat biodiesels. The combustion studies revealed that the ignition delay was shorter for biodieselstested compared to diesel and was increasing with the load. The neat simarouba biodiesel was proved to be bettersubstitute to diesel as it significantly reduced harmful exhaust emissions, showed better performance and combustioncharacteristicscomparedtoother twobiodiesels tested.
