Corrosion Characteristics of Copper in Malaysian Bioethanol and Gasoline blends
The present study aims to investigate the corrosion characteristics of copper commonly encountered in the spark ignition (SI) engine fuel system with Malaysian bioethanol and gasoline blends. Static immersion tests in E0 (gasoline), E10 and E85 were carried out at room temperature for 1320 h. Mec...

| Summary: | The present study aims to investigate the corrosion characteristics of copper commonly
encountered in the spark ignition (SI) engine fuel system with Malaysian bioethanol and gasoline
blends. Static immersion tests in E0 (gasoline), E10 and E85 were carried out at room temperature for
1320 h. Mechanical, physical and chemical properties of copper was investigated before and after
immersion tests. Investigations were carried out on change in morphological properties using optical
microscope; change in chemical structure using FTIR; change in mass and volume by weight loss
measurement; hardness changes using universal hardness tester; and change of chemical properties of
the fuel blends using total acid number titration method. The test results showed that corrosion of
copper was increased with the high concentration of ethanol in the blends. |
