Abstract

Dry cylinder-liners are partly inserted into the liquid cooled lower part a common cylinder head, which is fastened to an upwardly extended crankcase by means of crankshaft main bearing studs having their threads at the level of the inserted parts of the liners. Thus, cylinders and crankcase are stress-relieved, permitting a simple design and the use of less expensive materials and production methods.
