摘要

Waertsilae has introduced a 'D' version of its RT-flex50 low-speed marine engine, which is said to give a higher power rating and lower fuel consumption than the existing 'B' model. The maximum continuous power output has been raised by 5.1% from 1660kW/cylinder to 1745kW/cylinder, with the same running speed of 124rev/min. Featuring five to eight cylinders in-line, the 'D' version covers a power range of 6100kW to 13,960kW at 99rev/min to 124rev/ min.
