US 12,085,040 B2 · Large internal combustion engine

Abstract

The invention relates to a large internal combustion engine (1) with a crankcase (4), with a crankshaft (11) which is mounted rotatably in said crankcase (4), and with a crankshaft journal (10) on which a connecting rod (9) is pivotably arranged, wherein the crankcase (4) has an upper deck (O) and a lower deck (U) with in each case one opening for the cylinder liner (6), in which opening said cylinder liner (6) is arranged, and wherein the connecting rod (9) has an extent width (A) which is greater than the external diameter (a) of the cylinder liner (6). The problem addressed is that of specifying an improved large internal combustion engine. According to the invention, this is solved by virtue of the fact that the upper deck (O) and/or the lower deck (L′) have/has at least one clearance (FO, FU) for the installation of the connecting rod (9), and that the recess which is produced along the external diameter (a) of the cylinder liner (6) opens up at least an extent width (A) of the connecting rod (9) and has a breadth (W) which corresponds at least to a width (b) of the connecting rod (9). Moreover, the invention relates to an associated method for the assembly of the large internal combustion engine (1).
