B22 and B29 are 4-stroke engine models from Sulzer. B22s were manufactured in 3 to 8 cylinder versions. B22 has many submodels. BW22s, for instance, were mainly produced to be utilized in ship propulsion modules while BH22s were produced to be utilized as generator prime movers.
Most wear and tear on Sulzer RTA models will occur on parts such as cylinder liners, cylinder head parts (valves, seats, nozzles), plunger and barrels. The bore size of the original RTA series has an extensive range of 380 to 840 mm.
