The Sulzer RTA72U-B type engine is a lowspeed, direct-reversible, single-acting, two-stroke engine, comprising crosshead-guided running gear, hydraulically operated poppet-type exhaust valves, turbocharged uniflow scavenging system and oil-cooled pistons.
The Sulzer RTA72U-B is designed for running on a wide range of fuels from marine diesel oil (MDO) to heavy fuel oils (HFO) of different qualities.
Particular attention is drawn to the major changes compared with
RTA52U, 62U and 72U engines:
a) Three percent more power at R1, reduced rating layout field,
the lowest number of cylinders is 5.
!!!! b) RTA62U-B and RTA72U-B are shorter than RTA62U and RTA72U.
