“…Cr was emitted from the wear of compression rings, gears and cam bearings (Agarwal and Dhar, 2010). Pb, Al and Cu, could be from the coating material (Agarwal and Dhar, 2010), wear of pistons (Wander et al, 2011) and wear of bearings (Haseeb et al, 2011), respectively. Hu et al (2009) and Liati et al (2015) indicated that the vehicle lubricant contents could cause Ca, Zn, Mg, P and B emissions.…”

This study investigates the emission of a heavy-duty diesel engine generator fueled with waste cooking oil (WCO)-based biodiesel blends (W) and operated at 1.5 and 3.0 kW loads. A brand of pure fossil diesel was adopted as the base fuel, with 20% and 40% WCO-based biodiesel added into the based fuel to form W20 and W40 blends, respectively. The emission characteristics of PM, metals and PAHs were analyzed. Experimental results indicate that alternative WCO-based fuels had slightly higher fuel consumption rates (FCR) and brake specific fuel consumptions (BSFC) than conventional diesel (0.6-4.1% for FCR and 1.0-7.6% for BSFC), and similar engine thermal efficiency. The PM emissions reductions when using W20 and W40 were 19% and 6.5%, respectively, at 1.5 kW, and 27% and 19%, respectively, at 3.0 kW. The emissions of particle-bound metals were 13.6-13.8% lower when using W20 than using conventional diesel, but 12.0-12.3% higher when using W40. The metal contents of PM rose with the addition of WCO-based biodiesel. The metal elements of PM were dominated (> 90% mass) by Na, Mg, Al, K, Ca, Fe and Zn, while the major trace metals were Mn, Cu, Sr and Pb. The use of WCO-based biodiesel blends reduced the emissions of total-PAHs (44.0% in average) and totalBaP eq (80.2% in average). The mass reductions of MMW-and HMW-PAHs using W20 and W40 were more significant at 3.0 kW than at 1.5 kW, while the reduction of LMW-PAHs was greater at 1.5 kW than at 3.0 kW. Thus, the reduction in total-BaP eq was greater at the higher engine load. Accordingly, we conclude that the WCO-based biodiesel is a potential candidate of cleaner alternative energy sources.

“…Ramadhas et al [13] have conducted experiment on a four stroke direct injection single cylinder diesel engine fuelled with rubber seed oil and reported that the deposits on cylinder head were higher than that of diesel. Wander et al [14] have also reported higher carbon deposition for SME http (Soybean oil methyl ester) and CME (castor oil methyl esters) in a mono cylinder CI engine. While, another research has reported same level of carbon deposits on fuel injectors for both tested fuels; biodiesel (waste cooking oil) and diesel in a 7500 km field test in winter conditions [15].…”

“…In this case, inherent characteristics of fuel play dominating role for longer life of the components and smoother operation of engine. Wander et al [14] have conducted 1000 h endurance test with SME 100, CME 100 and diesel separately and demonstrated higher wear of pressure valve seating. This is due to greater use of these components.…”

“…The life and performance of lubricating oil is significantly affected by the engine oil dilution, and addition of different impurities such as wear debris, carbonaceous materials and impurities entering along with intake air [20]. There is a consistent evidence of engine oil dilution for all fuels [14,21]. However, the intensity of dilution increased significantly with application of more viscous and less volatile fuels like biodiesel.…”

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.
