The current basic family of MAN B&W's large medium-speed diesel engines consists of four sizes L 58/64, L/V 48/60, L 40/54 and L/V 32/40, launched between 1985 and 1995. This engine family covers an output range from 2,880 kW (6L 32/40) to 18,900 kW (18V 48/60). Within the last few years, this portfolio has been supplemented by the V 40/50, the smaller engine sizes L 16/24 and L 27/38, and, finally, the new L 21/31 (2002/03). All engines are fully heavy fuel oil compatible and have been optimized for both high fuel economy and lowest exhaust gas emissions. In terms of sold power, the 48/60 engine is second in the list of MAN B&W's bestsellers. The 48/60 has evolved with the needs of the market in its 13 years.
