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

Abstract

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

SrO‐MnO/Ceramic: A Novel Bifunctional Catalyst for Biodiesel production via Simultaneous Transesterification‐Esterification of Waste Frying Oil

“…The high corrosion resistance in stainless steel might be due to the carbon content (0.98 % by weight) in its composition [72] . As can be observed, in comparison with other metals copper was more prone to corrosion owing to its high weight loss (8 mg in B50 blend) [73] . Enzhu et al.…”

“…[72] As can be observed, in comparison with other metals copper was more prone to corrosion owing to its high weight loss (8 mg in B50 blend). [73] Enzhu et al reported the high corrosion in copper was due to its easy oxidation, which leads to formation of metal oxides (CuO, Cu 2 O). [74] The corrosion rate of zinc was higher than aluminium and galvanized steel in blends and B100.…”

Study of Corrosion, Wear, and Thermal Analysis of Materials for Internal Combustion Engines and their Compatibility: A Review

“…Biodiesels are associated with corrosive elements which affect the different parts of the internal combustion engine. Shahabuddin et al [31] investigated the corrosion performance of automotive component materials like cast iron, copper and stainless steel in varying volume concentrations of Jatropha biodiesel via immersion test. Fuel properties like oxidation stability, total acid content, viscosity, density and water content were analysed by scanning electron microscopy and optical microscopy to check the corroded parts' morphology.…”

Thermoelectric Generator as the Waste Heat Recovery Unit of Proton Exchange Membrane Fuel Cell: A Numerical Study

“…Concentrated efforts have been made to reduce the usage of fossil fuels after ascertaining their adverse contributions to climate change and pollution [1]. The automotive industry still largely relies on internal combustion engines fueled by diesel [2]. However, fuel cells and batteries are becoming viable alternatives to diminish and also control the localization of pollutant emissions [3].…”
