A Study on the Corrosion Characteristics of Internal Combustion Engine Materials in Second-Generation Jatropha Curcas Biodiesel

The corrosiveness of biodiesel affects the fuel processing infrastructure and different parts an internal combustion (IC) engine. present study investigates corrosion behaviour automotive materials such as stainless steel, aluminium, cast iron, copper in 20% (B20) 30% (B30) by volume second-generation Jatropha using immersion test. results were compared with petro-diesel (B0). Various properties viscosity, density, water content, total acid number (TAN), oxidation stability investigated after test ASTM D341, D975, D445, D6751 standards. morphology corroded was optical microscopy scanning electron SEM), whereas elemental analysis carried out energy-dispersive X-ray spectroscopy (EDS). highest detected copper, while lowest steel. Using B20, rate steel 17% 14% higher than when diesel, which further increased to 206% 86% B30. After test, TAN markedly petro-diesel.
