FIXED CYLINDER HEAD ENGINE WITH ADDED-IN BEARINGS

摘要

Method of manufacturing a fixed cylinder head internal combustion engine (1) comprising at least one cylinder (10), involving the following steps: a) creating a casting that will form the fixed cylinder head engine, comprising a crank case (14) and at least one cylindrical chamber (11) of base surface area s and height h, opening at a bottom end into the crank case; b) creating a liner (20) in the form of a cylindrical tube the diameter of which is less than or equal to the diameter of the cylindrical chamber (11); c) fitting said liner (20) via the crank case into the cylindrical chamber (11); d) creating a bearing (16) and a bearing cap (17) for supporting a crank shaft (15) comprising at least two holes for the passage of fixing screws for said bearing and said bearing cap, characterized in that said bearing (16) is added on to the roof of the wall of the crank case (14) and in that at least one portion of said bearing is situated below the base surface of the cylindrical chamber (11).
