Abstract

A multi-cylinder internal combustion engine which is assembled from two identical engines with an opposed piston-type arrangement and disposed symmetrically above one another, in which each of the two identical cylinder-crankcases are welded together from cast housing elements adjoined in a building-block-like manner whereby the connection with each other of the two cylinder-crankcases takes place by way of flanged surfaces and the sides accessible from the top or bottom of the respective cylinder-crankcase is open for the installation of the crankshaft the housing elements thereby include cross walls which are constructed for receiving the crankshaft main bearings and bifurcate Y-shaped in the direction toward the flanged surfaces for the other engine.
