FUEL SUPPLY DEVICE AND FUEL SUPPLY METHOD

摘要

The mixing ratio of mixed oil generated by mixing fuel oils with different viscosities is set to satisfy a preset viscosity condition. A CPU (49) generates mixed oil on the basis of a mixing ratio by controlling flow regulating valves (23, 24) in a blender (13). The viscosity is detected by a viscometer (33) while the mixed oil is supplied to an engine (14) by driving a pressure pump (32). Based on a result of the detection, the CPU (49) corrects the mixing ratio so that the viscosity of the mixed oil satisfies the viscosity condition and the content of a fuel oil with the highest viscosity out of the fuel oils constituting the mixed oil is maximum.
