“…According to their observation, the increasing in the wear resistance of the steel surfaces depends strongly on the type of additives, tribofilms composition, and temperature. Sulek et al 22 suggested that wear can be characterized by analyzing the profile of the wear scar, by such measures it can be confirmed that the wear is not a monotonic function of the concentration of ester. Figures 6 and 7 show the superficial roughness of these discs, with non-contact region (on the left) and worn condition, i.e., wear profiles measured perpendicular to the friction path (on the right).…”

The contact of diesel fuel with engine subsystems demands a good wear resistance. Lubricity is an important feature for integrity of injection system and the sulphur composites are primarily responsible for lubrication of the injector nozzle. Biodiesel is responsible for partially restoring the lubricity of diesel fuel that presents low levels of sulphur composites and, furthermore, it causes less pollution than diesel fuel. The lubricity is measured through the wear scar diameter following the ASTM D 975 standards. However, the friction and wear with light loads of micro/nanocomponents are highly dependent on surface interactions that can be evaluated by microscopy techniques. This study aimed to measure and to analyze the biodiesel lubricity and their blends (B5, B20) with diesel by observing the wear scars of discs using the scanning electronic microscopy (SEM), atomic force microscopy (AFM) and micro roughness techniques. The fuels performance was evaluated using HFRR tribometer. The tests conditions were based on standard ADTM D-6079-04. The coefficient of friction was measure during the test. After the test, the worn ball and disc were analyzed by SEM, AFM and profilometer. The results showed that the addition of biodiesel in diesel improve the tribological performance of fuel. Also, the just WSD value is not sufficient to evaluate the lubrication ability of a fuel. Analysis of the worn disc surfaces proved to be compatible with WSD number and also more sensitive to these kinds of fuels, showing mainly the form and intensity of the wear.

“…Although WEO was once used as an ingredient in animal feed, it was banned by the European Union because of animal health hazards. 9,10 The disposal of large amounts of WEO is problematic in numerous countries. Production of biodiesel from waste cooking oil is one of the less problematic methods of using it efficiently and economically.…”

Meeting the growing demand for sustainable energy is one of the major challenges of the 21st century. In the Kyoto conference on global climate change, numerous nations committed to large reductions in greenhouse gas emissions. Reduced greenhouse gas emissions are a major advantage of using biodiesel on diesel engines. The test uses three biodiesels (soybean oil, palm oil, and waste edible oil) in the engine, comparing engine performance and exhaust emissions with the baseline (pure petrodiesel) case. The results indicated that the use of biodiesel produces decreased smoke opacity but increased fuel consumption up to 7.38% compared with petrodiesel. Exhaust emissions, such as CO and HC, were reduced using biodiesel in fuels, primarily because of the effect of complete combustion of the oxygen contained in biodiesel.

“…Therefore, to promote the use of biofuel, the performance and lubricity characteristics of biofuel blends used in a diesel engine must be evaluated. 26) For tribologists, continuing challenges in engine design include reduced emissions and increased operating temperatures. The resulting engine systems must also meet the strict emissions and fuel economy targets that have been recently established.…”

To extend the engine life and to reduce exhaust pollution in diesel engines, lubrication properties were compared between the biodiesel blends and pure petroleum diesel. The biodiesel was used as lubricating additives on pure petroleum diesel at five different concentrations of 0 mass%, 10 mass%, 20 mass%, 50 mass% and 100 mass%, biodiesel blends were named B0, B10, B20, B50 and B100 biodiesel blends, respectively.The analysis was performed in three steps. First, the injection of biodiesel in the diesel engine channel was simulated. Second, tribological experiments were performed using ball-on-ring contact method. The wear scar diameters and wear surfaces of the tribopairs were then analyzed. The third step was comparison of biodiesel blends and pure petroleum diesel in terms of engine exhaust emitted by a turbocharged diesel engine.The wear experiments showed that a small addition of biodiesel to pure petroleum diesel can considerably reduce friction and wear under boundary lubrication. The third tests apply four biodiesel fuel additives on the engine performance, and exhaust emissions results are compared to the baseline (pure petroleum diesel) case. Results show that the fuel consumption is increased by 11.8% for the biodiesel case, the engine combustion temperature can be increased by 2.49% for the biodiesel case; the O 2 emission can be increased by 12.85%; smoke emissions can be reduced up to 15.89%. Thus, the biodiesel additives can be applied in the diesel fuel to upgrade the engine performance.
