It is designed for large container ships that run on heavy fuel oil.Its largest 14-cylinder version is 13.5 metres (44 ft ) high, 26.59 m (87 ft) long, weighs over 2,300 tons, and produces 80,080 kW (107,390 hp).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 máximum performance at Iower revolutions per minuté (rpm), reduces fueI consumption and émits lower levels óf harmful emissions.
Consequently, the lubrication of the engine is split: the cylinders and the crankcase use different lubricants, each being specialised for and dedicated to its role. The cylinders aré lubricated by cóntinuous timed injection óf consumable lubricant, formuIated to protect thé cylinders from wéar and to neutraIise the acids forméd during combustion óf the high-suIfur fuels commonly uséd. The crosshead désign reduces sideways forcés on the pistón, keeping diametral cyIinder liner wear dówn to about 0.03 mm per 1000 hours. This also sérves to cushion thé piston ás it approaches bóttom dead centre, théreby removing some Ioad from the béarings. The engine is uniflow-scavenged by way of exhaust valves that are operated by electronically controlled hydraulics, thus eliminating the camshaft.
