DEVELOPMENT TEST RESULTS OF IHI-SULZER 9RLA90 TYPE MARINE DIESEL ENGINE (THE FIRST UNIT)

IHI has completed the first unit of the IHI-SULZER 9RLA90 type marine diesel engine featuring low fuel consumption, high output and low speed (32,400 PS time 98 rmp). This output represents the highest among the RLA90 type Sulzer engines to be produced so far in the world. A series of shop trials was conducted on this engine during a period of 2 months from October 1, 1979, to verify its performance and reliability. The results duly demonstrated the expected performance of this engine in terms of fuel consumption, with the very favorable figure of 137.2 g/PS-h at maximum continuous rating, and 136.7 g/PS-h at normal service output (85% load). This already low consumption at normal service output was further reduced to the record-breaking figure of 135.3 g/PS-h when the newly developed variable injection timing device was applied in operation. This engine was subsequently mounted on the 1,197 TEU container ship "Japan Apollo" of the Japan Line Ltd., constructed at IHI's Aioi Shipyard, and in April 1980 the ship sailed on its maiden voyage on the North Pacific route. This article presents an outline description of the engine, together with results obtained from the shop trials.
