Page 509 The fuel as bunkered must be processed before it goes into the engine. It is recommended that you refer to the related specifications of WinGD for the design of the fuel treatment plant. The minimum separator capacity is 1.2 x CMCR x BSFC / 1000 (liters/hour), which is related to 0.21 l ⁄ kW.
Page 510 For Generation X, X-DF and RT-flex engines, the fuel viscosity at the engine inlet must be in the range between 10 mm /s and 20 mm /s, but WinGD recommends a fuel viscosity at the engine inlet in the range between 13 mm /s and 17 mm /s.
Page 511 The paragraphs that follow give more data about the specifications for HFO. 12.4.3.1 Viscosity WinGD recommends a viscosity range at the engine inlet between 13 mm /s (cSt) and 17 mm (cSt). You get the necessary temperature for a given nominal viscosity from the data in Figure 12-1.
