Abstract: Biodiesel from vegetable oil is one of the best alternatives for diesel needs. Pongamia pinnata is a evergreen tree had a high capacity to become an alternative fuel for replacing diesel fuel. Pongamia oil cannot be used directly, why because its having high viscosity compare to diesel fuel, and so affects the characteristics of combustion . The oil of pongamia is esterifies to decrease the value of viscosity and based on volume it was blended with diesel for different proportions. And the energy of the biodiesel may be released high efficiently by the concept of Low Heat Rejection (LHR) engine. In this experiment applying Thermal Barrier Coatings (TBC) onto engine parts of cylinder headd, pistonn and vvalves for improving performance offengine; pongamia oil wass used assannalternativeefuel. So normal diesellengine was converted as a LHR engine by applying yittria stabilized zirconia (TBC) layer with a thickness of 0.50 mm on the engine parts. And that engine were tested for different load
