Uncommon card · No. 136262

The Wärtsilä RT-flex96C is a two-stroke turbocharged low-speed diesel engine designed by WinGD. It is designed for large container ships that run on heavy fuel oil. Its largest 14-cylinder version is 13.5 m (44 ft) high, 26.59 m (87.2 ft) long, weighs over 2,300 t (2,535 short tons; 2,264 long tons), and produces 80.08 MW (107,390 hp). It is the largest reciprocating engine in the world. The 14-cylinder version first entered commercial service in September 2006 aboard the Emma Mærsk. The design is similar to the older RTA96C engine, but with common rail technology (in place of traditional camshaft, chain gear, fuel pump and hydraulic actuator systems). This provides maximum performance at lower revolutions per minute (rpm), reduces fuel consumption and emits lower levels of harmful emissions. The engine has crosshead bearings so the always-vertical piston rods create a tight seal under the pistons. Consequently, the lubrication of the engine is split: the cylinders and the crankcase use...
