Abstract: Increasing the performance of an internal combustion engine requires the transformation of total fuel energy to useful energy at the highest as possible. Increase of inner cylinder heat plays important role in the increase of engine performance and decrease of exhaust emissions. It is understood that coating combustion chamber elements with thermal barriers contributes a lot to the increase of inner cylinder heat. This study includes an evaluation of experimental studies and its results carried out upon the methods applied on coating with thermal barrier in diesel engines, the effects of coating on the performance of engine using rice bran oil biodiesel blends of B10, B20, B40, B100 with the diesel fuel. By using rice bran biodiesel blends with diesel fuel, the result showed that brake thermal efficiency and mechanical efficiency of different blends with diesel fuel were less as compared to conventional diesel. Fuel consumption was increased with blending percentage in the engine. Emission level of HC decreased (40-50 %) with blending percentage increased with all type of fuel modes. NOx , CO also decreased with blending percentage increased with diesel fuel.
