TOPICS FOR SPEAKING CYLINDER FRAME The cylinder section of the engine consists of a number of cylinder blocks, which are tightened together with the engine frame and the bedplate by means of through- going stay bolts. Two central bores, one at the top and one halfway down inside the cylinder block, enclose the cylinder liner. The upper part of the cylinder block forms part of the cooling water space around the central part of the cylinder liner, whereas the lower part forms the scavenge air space. A central bore in the bottom of the cylinder block encloses the piston rod stuffing box. The bottom is double with a hollow space through which cooling water is circulated. On the exhaust side of the cylinder block there is a circular opening leading into the longitudinal scavenge air receiver of the engine.
