“…Similar trend can be seen in Figure 2 (b) which shows the normalised NOx emissions. The result from this study aligns with another study which used waste lubricating oil and NOx emissions decreased by 15% [38].…”

“…Therefore, there is potential to use it as a fuel, however, using this alternative fuels should not compromise the engine emissions and performance. There are studies in the literature evaluating the use of lubricating oil as a fuel [23,[36][37][38][39][40]. However, in the literature, there is no such fundamental study which evaluates the influence of waste lubricating oil on NOx emissions under transient engine temperature during stages of cold-start, given that it is a significantly important period where after-treatment systems are not effective [7].…”

NOx emissions from diesel engines are a concern from both environmental and health perspectives.Recently this attention has targeted cold-start emissions highlighting that emission after-treatment systems are not effective in this period. Using a 6-cylinder, turbocharged, common-rail diesel engine, the current research investigates NOx emissions during cold-start using different engine performance parameters. In addition, it studies the influence of waste lubricating oil on NOx emissions introducing it as a fuel additive (1 and 5% by volume). To interpret the NOx formation, this study evaluates different parameters: exhaust gas temperature, engine oil temperature, engine coolant temperature, start of injection/combustion, in-cylinder pressure, heat release rate, maximum in-cylinder pressure and maximum rate of pressure rise. This study clarified how cold-start NOx increases as the engine is warming up while in general cold-start NOx is higher than hot-start. Results showed that in comparison with warmed up condition, during cold-start NOx, maximum in-cylinder pressure and maximum rate of pressure rise were higher; while start of injection, start of combustion and ignition delay were lower.During cold-start increased engine temperature was associated with decreasing maximum rate of pressure rise and peak apparent heat release rate. During cold-start NOx increased with temperature and it dropped sharply due to the delayed start of injection. This study also showed that using waste lubricating oil decreased NOx and maximum rate of pressure rise; and increased maximum in-cylinder pressure. NOx had a direct correlation with the maximum rate of pressure rise; and an inverse correlation with the maximum in-cylinder pressure.

“…Whereas non-active gears are usually placed for several days before being hauled, and the target species swing towards the net, trap, or hooks and lines. Recently, eight types of fishing gears have been analyzed in several project at AZTI (Basurko et al, 2013;Gabiña et al, 2016;Uriondo et al, 2018), showing that their fuel consumption varies from 1.94 L/ mile to 74.2 L/mile (Table 4).…”

“…In the literature, there are some studies evaluating waste lubricating oil as a fuel [32,35,[39][40][41]. However, the authors could not find any study investigating the influence of using this fuel on PN, PN size distribution, friction losses and combustion instability parameters during different stages of cold start in comparison to hot start; cold start operation is of significant importance owing to the fact that during this period the after-treatment systems do not perform well.…”
