“…In contrast, biodiesel pure with an operational period of only 200 h led to reductions (7%) in the hole size [36]. Furthermore, the original machining marks of the nozzle were also covered as a result of the use of biodiesel [37], just like in this work (see Figure 7). There was also variation in injector hole dimensions, and the topography of the nozzle surface was obtained with biodiesel without changing engine performance, so the 50PF50D fuel blend does not cause any modifications in the operation of the engine either.…”

Common rail (CR) diesel fuel injection systems are very sensitive to variations in fuel properties, thus the impact of alternative fuels on the durability of the injection system should be investigated when considering the use of alternative fuels. This work studies a high-pressure CR (HPCR) diesel fuel injection system operating for 400 h in an injection test bench, using a fuel blend composed of an alternative paraffinic fuel and conventional diesel (50PF50D). The alternative fuel does not have aromatic components and has lower density than conventional diesel fuel. The injection system durability study was carried out under typical injection pressure and fuel temperature for the fuel pump, the common rail and the injector. The results show that the HPCR fuel injection system and its components (e.g., piston, spring, cylinder, driveshaft and cam) have no indication of damage, wear or change in surface roughness. The absence of internal wear to the components of the injection system is supported by the approximately constant total flow rate that reaches the injector during the whole the 400 h of the experiment. However, the size of the injector nozzle holes was decreased (approximately 12%), being consistent with the increase in the return fuel flow of the injector and rail (approximately 13%) after the completion of the study. Overall, the injection system maintained its operability during the whole duration of the durability study, which encourages the use of paraffinic fuels as an alternative to conventional diesel fuel.

“…Fuel contains oxygen, which leads to more wear with high sulfur contents. Metal surfaces come into contact through the chemical reaction between oxygen and unsaturated fatty acid, which consists of biodiesel [137]. Problems such as changing lubricating properties, carbon deposits, and sticking of piston ring were observed in diesel engines after long-term operation with biodiesel [138].…”

a b s t r a c tA biomass oil/diesel blend was prepared using an emulsion method and combusted in a diesel engine. An injector was then removed and the morphology, composition, and structure of the carbonaceous deposits on the pintle-type nozzle were characterized using a combination of HRTEM, SEM/EDAX, Raman and XRD. Results showed that the carbon deposition of the emulsified fuel with high crystallinity was greater than that of diesel. The agglomerated particulate diameters of the deposited carbon from diesel and emulsified fuel were approximately 10-30 μm and 50 μm, respectively. The carbon deposition mechanism from the emulsified fuel was attributed to the high oxygen content of the groups leading to increased polymerization and subsequent condensation on the nozzle surfaces that was then carbonised.
