“…However, because biodiesel has an oxidant potential greater than that of diesel oil, it can potentially cause greater corrosion (Sgroi et al, 2005;Tsuchiya et al, 2006;Jain and Sharma, 2010b), although the engine wear is similar to that observed when using traditional diesel oil (Dorado, 2003;Khan et al, 2009). Finally, it has solvency properties for several types of polymeric materials, which means it can cause structural degradation (Gonzales Prieto et al, 2008;Trakarnpruk and Porntangjitlikit, 2008;Haseeb et al, 2010).…”

The performance of a 118-kW tractor fuelled by pure biodiesel was monitored during a long-term field experiment with\ud approximately 800 h of engine function. The objective was to demonstrate that B100, a pure biodiesel fuel, is a viable alternative to\ud traditional diesel oil in terms of long-term mechanical reliability. A bench test on the new engine, performed by attaching a test stand to\ud the power take-off of the tractor, showed an expected reduction in power (–9%) and torque (–7%) and an increase in specific consumption\ud (+13%) when biodiesel was used as a complete substitute to diesel oil. Furthermore, with the same setup, the exhaust gas had a Bosch\ud smoke index equal to 50% of the value for the same engine fuelled with diesel oil. After these initial tests, the tractor was set up for\ud normal field operations, in which both the engine curves and lubricant quality were periodically monitored. These surveys indicated\ud no significant reduction in engine performance; however, the lubricant was consequently diluted and contaminated by biodiesel, which\ud caused the lubricant properties to considerably worsen. However, on the basis of the chemical–physical analysis, reducing the oil\ud change interval from 200 h (manufacturer’s indications for the engine when operating with diesel oil) to 100 h would compensate for\ud this progressive quality decline. At the end of the trials, the engine was disassembled to check the condition of its components; wear\ud and lacquer-like coating phenomena were observed, and their levels were acceptable. The obtained results demonstrated that B100\ud can effectively substitute for diesel oil in a standard compression-ignition engine: the power change is not perceptible during normal\ud operation of a tractor, and no particular problem will arise in the engine during its life if the lubricant is changed every 100 h

“…Table-1 represents the hardness of as-received PPA and hardness after the immersion at different conditions. No change in hardness of the material has observed for the PPA test coupons exposed to B0 and B100 at 25 °C for 120 h. While, there was slight decrease in hardness of test coupons exposed to 25 °C for 720 h. A significant drop in hardness was noticed at 75 °C for 120 h. From the investigation, it can be inferred that the hardness of PPA greatly decreases when exposed to elevated temperatures [13]. On the other hand, Table-2 represents the hardness of asreceived PAA and hardness after immersion at various conditions.…”

“…Similarly, glycol dimethacrylates is the crosslinking agent for polychloroprene, which resists swelling. Impact of diesel and biodiesel on these different ingredients of polymers bears different characteristics based on their dissolution capabilities as well as their molecular polarities [13]. There is a general rule describing the fact that polar substances are more likely to dissolve in polar solvents and non-polar substances are more likely to dissolve in nonpolar solvents [14].…”

Material compatibility with biodiesels and their blends should be verified on a case-by-case basis to ensure long term durability of storage tanks and pipelines. This paper aimed to investigate the degradation of physical properties such as mass, volume, tensile strength, hardness and change in surface morphology for polymers namely polypthalamide (PPA) and polyarylamide (PAA) upon exposure to Pongamia pinnata biodiesel (PPB) and blends. Static immersion tests in B0, B10, B20 and B100 were carried out at 25, 50 and 75 °C for 120, 360 and 720 h to estimate the degradation behaviour of polymers under static condition. Rotating cage was used to study the degradation behaviour at room temperature for 120 h under flow conditions. Significant changes in the physical properties and surface morphology was observed. The overall compatibility sequence of polymers in Pongamia pinnata biodiesel under static condition was found to be PAA > PPA while under flow condition, the order is and PPA > PAA under flow condition.

“…These studies were motivated by the compatibility of elastomers and biodiesel, which remains a major challenge to date (Haseeb et al, 2010). This concern arises especially when elastomeric components start to degrade in terms of mechanical properties even without any simultaneous imposed loading (Trakarnpruk and Porntangjitlikit, 2008;Haseeb et al, 2010;Alves et al, 2013).…”

“…No studies are reported for the fatigue of swollen elastomers by palm biodiesel to date. The current studies, which deal with the effect of palm biodiesel diffusion on the behavior of rubbers, investigate the change of mass, volume, hardness and tensile strength of rubbers for different immersion durations (Trakarnpruk and Porntangjitlikit, 2008;Haseeb et al, 2010Haseeb et al, , 2011Alves et al, 2013). Haseeb et al (2011) had immersed nitrile rubbers in diesel and biodiesel for 1000 hours at room temperature prior to subjecting the specimens to tensile tests.…”

The compatibility of the properties of elastomer with conventional diesel fuel has made it favourable in many engineering applications. However, due to global energy insecurity issues, there is an urgent need to find alternative renewable sources of energy as replacements to conventional diesel. In this respect, biodiesel appears to be a promising candidate. Hence, research into the compatibility and fatigue characteristics of elastomers exposed to biodiesel becomes essential. The present paper introduces the first attempt to investigate the effect of different solvents on the fatigue of swollen elastomers. The filled nitrile rubbers are immersed in the palm biodiesel and conventional diesel to obtain the same degree of swelling prior to the application of uniaxial fatigue loading. Field Emission Scanning Electron Microscopy (FESEM) analysis is carried out to observe the fracture surfaces. Stretch-N curves are plotted to illustrate the fatigue life duration. These curves showed that the fatigue lifetime of rubber is the longest for dry rubber and the least for rubber swollen in biodiesel. FESEM micrographs reveal that the loading conditions have no effect on the crack initiation and propagation patterns regardless of the swelling state.
