Top of the Main Engine. This Japanese built B&W Engine has 7 cylinders, a bore of almost 3 feet and a 7 foot stroke. Top speed is 94 rpm.
A little different view of the Engine. The big hoses are hydraulic actuators for the Exhaust Valves.Smaller hoses are high pressure fuel lines.
This is the Control Air Compressor, one of 5 large air compressors in the Engine Room. The output from this is used in pneumatic control systems for the Main Engine and other control systems all over the Engine Room.
This is the Main Engine Turbocharger casing. To give some perspective, the silver part is about 3 feet in diameter. The rotor inside rotates at about 15,000 rpm when the engine is running at sea.
All electricity is produced using this and three other Wartsila Diesel Generators. Two of them are 4 cylinders and two are 6.
Also in the generator flat is this 1000 horspower Stern Thruster Motor. It powers a large pump which jets water to one side or another, thrusting the ship in the opposite direction. It is used as an aid in docking.
