PURPOSE: A large engine including a cylinder lubricating device and a cylinder lubricating method of thereof are provided to prevent a generation of a fluid medium by a much higher pressure P2 in a second connection line when a first connection line is leaking. CONSTITUTION: A large engine including a cylinder lubricating device comprises a cylinder liner, a piston, a drive shaft, and connection elements (13, 14). The piston is arranged to displace in the cylinder liner. The connection element connects the drive shaft to the piston. A device for lubricating or cooling the cylinder and/or the piston and/or the connection element by the fluid medium is included. The large engine comprises a first connection line (11) for transporting the fluid medium from a reservoir to a used place. At least a part of the first connection line spreads through the connection element. The fluid medium inside the first connection line is pressurized by a pressure P1 materially. A second connection line (12) in which the fluid medium pressurized by a pressure P2 is accommodated is provided. The pressure P2 is higher than a maximum pressure P1 in a normal operation mode. |
