	Members of this Institute will surely agree with the author that the problem presented by the designing of new types of engines for marine work is far from easy. In addition, shipowners generally order their new tonnage for delivery in the shortest possible time. The machinery must be ready for installation immediately the vessel has taken the water, and no excuses are accepted even if, for some unforeseen reason, it is desirable to prolong the test bed trials.
