“…In addition to this, the usability of biodiesel may vary depending on many parameters it includes. Undesirable substances in biodiesel negatively affect engine performance by reducing the combustion heat of the fuel, which leads to increased corrosion on metal parts [4]. There beside, along with the increase in viscosity, the combustion process in the engine and the power production of the engine are negatively affected.…”

Selection of material for automotive component has an important role to avoid wear problem that encountered in static and moving parts due to fuels used in the engine especially, biodiesel. Biodiesel compositions such as dissolved water, free water and emulsified water accelerate oxidation of metallic materials. During the combustion process, the biodiesel contributes to the corrosive wear of the engine components leading to the shortening of the life span. The early prediction of the wear behavior under severe conditions in presence of biodiesel would be a vital solution. Therefore, the main aim of this study is to propose a wear map simulation for examining wear phenomenon of automotive component materials in presence of biodiesel. Herewith, materials that come into contact with biofuel/biodiesel in automotive application are highlighted for better design and selection in the future. This study concluded that based on the wear map simulation proper selection of material with higher durability and wear resistant can offer a better future for economic and reliability of the components. The development of wear map with recommendation aids researchers making decisions and innovation on the metals engine components. Furthermore, a full explanation on the reaction between biodiesel and metals can increase the innovation in the automotive industry.

“…Metallic storage tanks such as stainless steel and Al are normally used for storage [95], while in automobiles, the fuel is in direct contact with various parts of the engine like the fuel pump, fuel injector, pistons and piston rings, which are made of Cu, Al, brass-Br (copper-rich alloy) and bronze [93]. Meanwhile, Cu has a huge effect on oxidizing biodiesel [96] and assessing Cu, Fe, and Zn is very crucial since along with Ni, Sn and brass, they can affect stability through oxidation [97].…”

The world is currently faced with the depletion of fossil fuel energy sources and their use is associated with environmental pollution. This has triggered the need to seek alternative energy sources that are renewable, sustainable and environmentally benign. Biodiesel, an alternative fuel of interest, is obtainable from biomass feedstocks. In existing biodiesel fuel, there are concerns that it is a contaminant due to its elemental contents, which over time also affect its quality. This study aimed to investigate the influence of a bifunctional catalyst on the conversion of free fatty acids and the elemental composition of biodiesel obtained from waste oils of sunflower and palm feedstocks. The synthesised catalyst was characterised using BET, XRD, FTIR and SEM while ICP-OES and Rancimat were used for elemental contents and oxidation in feedstocks and biodiesels. The effect of Cu, Zn and Fe metals on the stability of synthesised biodiesel was further studied. The catalyst showed characteristics of bifunctionality with improved textural properties necessary for the conversion of high free fatty acids feedstocks to biodiesel, despite increasing Ca content within the produced biodiesel. Sunflower biodiesel showed superior fuel quality, although palm biodiesel had more oxidation stability. An increase in the concentration of metals decreased the induction period, with Cu and Fe being more effective than Zn metal.

“…Copper was chosen for the immersion test, as it is used in internal combustion engine systems, and gaskets utilize copper-based alloys and copper, respectively [24]. According to [28], copper may oxidize biodiesel and generate sediments.…”

“…The amount of unsaturated free fatty acid in the raw material for biodiesel production has a high impact on the oxidation rate. The metals commonly used in compression ignition engines, such as copper and copper alloys, steel, and aluminum, are prone to corrosion [23,24]. Inhibitors ethylenediamine, tert-butylamine (TBA), and n-butylamine formed a stable metal oxide protective layer and thus retarded the corrosion in biodiesel [23,25].…”

Used cooking oils (UCOs) have a high potential as renewable fuels for the maritime shipping industry. However, their corrosiveness during storage and usage are some of the concerns yet to be investigated for addressing compatibility issues. Thus, the corrosion of steels and copper exposed to the UCOs was studied through the immersion of metal rods for different periods. The changes on the rod surfaces were analyzed with a scanning electron microscope (SEM). After the immersion, the copper concentration dissolved in the bio-oils was measured using inductively coupled plasma-optical emission spectrometry (ICP-OES). The free fatty acids and glycerides were analyzed using gas chromatography with flame ionization detection (GC-FID). The acid number (AN), water concentration, as well as density and kinematic viscosity of the bio-oils were determined with standard methods. The UCOs with the highest water content were corrosive, while the oils with lower water concentrations but higher ANs induced lower corrosion. After mixing two different UCOs, the metal corrosion decreased with an increasing concentration of the oil with lower corrosive properties. The lower corrosion properties were most likely due to the monounsaturated fatty acids, e.g., oleic acid in oils. These acids formed a barrier layer on the rod surfaces, thereby inhibiting the permeation of oxygen and water to the surface. Even adding 0.025 wt% of tert-butylamine decreased the corrosivity of UCO against polished steel rod. The results suggested that mixing several oil batches and adding a suitable inhibitor reduces the potential corrosive properties of UCOs.
