WITHDRAWN: Investigation on the behavior of single cylinder diesel engine using diesel blended with jatropha oil as an alternate fuel

Abstract

Abstract Nowadays usage of automobiles is inevitable which leads to higher emission rate. In order to control the emission rate many researches are being carried out to find the alternative fuels by blending diesel with other natural oils. Jatropha oil is the permissible to be an automotive fuel for specifically designed engines or otherwise with suitable blending with gasoline can be used in the existing engine without engine modifications. this work contemplates the durability and corrosion test of a single cylinder diesel engine using the fuel blended with 20% jatropha oil and 80% diesel and it also emphasis the demonstration of the the lubricant qualities on engine performance. Notably, it details the experimental characteristics of B20 bio-fuels on the short run performance (life cycle endurance) of IC engine and there is no remarkable reduction in performance of the engine. However, it is significant to witness the dilution and contamination by bio- diesel thereby effect in detrimental lubricant properties, in this regarding experimental trails on abnormal observations such as wear, and lacquer-like carbon coating were made inside the engine inner components and its constructive characterization were also been witnessed. The viscosity and the contamination of the lubricating oil were also observed that the study reveals there is a significant carbon deposit in engine component after 100 h. The material presents increase with increasing of testing time. The PPM value of the iron is the highest reported among tested 8 elements. The contaminants PPM illustrate the sulphate level are quite high and contributing more than 40% followed by silicon, sodium and other oxidations. The experimental results confirm that the B20 can be used as an effective alternative for diesel oil-based CI engine.
