Marine Propulsion Diesel Engine Progress 881162

As a designer and licensor of both two-stroke crosshead and medium speed trunk piston diesel engines, MAN B&W offers the industry engines in the power range from approx. 600 HP up to some 64,000 HP per unit. Whereas the four-stroke engine programme embodies engines with power outputs of up to some 19,000 HP per unit, the two-stroke programme starts at approx. 2000 HP per unit giving a considerable overlap in the medium power range so as to enhance the application possibilities.
Over the years the distribution on two-stroke and four-stroke engine production has been fairly constant, whether counted as a whole or for MAN B&W engines only.
This paper will, in particular, discuss the ongoing development and application potential of the MC-range of two-stroke engines which were introduced in 1982, and which have proved to be our Company's most successful engine programme so far, both in respect to engine sales and actual experience. Fig. 1 shows one of the large MC engines on testbed, and design details of the engines can be found in Ref. 1.
