two-stroke diesel engine
| Some facts on the 14 cylinder version: | ||
| Total engine weight: | 2300 tons (The crankshaft alone weighs 300 tons.) | |
| Length: | 89 feet | |
| Height: | 44 feet | |
| Maximum power: | 108,920 hp at 102 rpm | |
| Maximum torque: | 5,608,312 lb/ft at 102rpm | |
at its most efficient power setting, the big 14 consumes 1,660 gallons of heavy fuel oil per hour.
Installing the "thin-shell" bearings. Crank & rod journals are 38" in diameter and 16" wide
Some pistons
The "spikes" on the piston rods are hollow tubes that go into the holes you can see on the bottom of the pistons (left picture) and inject oil into the inside of the piston which keeps the top of the piston from overheating. Some high-performance auto engines have a similar feature where an oil squirter nozzle squirts oil onto the bottom of the piston.
some piston rods:
A piston & piston rod assembly. The piston is at the top. The large square plate at the bottom is where the whole assembly attaches to the crosshead:
The crank sitting in the block (also known as a "gondola-style" bedplate). This is a 10 cylinder version.
Note the steps by each crank throw that lead down into the crankcase:
The cylinder deck (10 cylinder version). Cylinder liners are die-cast ductile cast iron. Look at the size of those head studs!
