<div class="htmlview paragraph">As a designer and licensor of both two-stroke crosshead and medium speed trunk piston diesel engines, MAN B&amp;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.</div> <div class="htmlview paragraph">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&amp;W engines only.</div> <div class="htmlview paragraph">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. <span class="xref">Fig. 1</span> shows one of the large MC engines on testbed, and design details of the engines can be found in <span class="xref">Ref. 1</span>.</div>
