ABSTRACT:
A housing for a turbocharger comprises a housing shell which surrounds, at least partially, a rotor space, at least one manifold of a combustion engine, a pipe for connecting the housing shell with at least one manifold of the combustion engine, and a cylinder head of said combustion engine. All these parts are integrally cast as one single piece. This may be effected by a method which comprises the steps of: joining and bonding sand cores for part of a housing shell of the turbocharger with sand cores for shaping the cavities of the manifold, and these, in turn, with sand cores for shaping the cylinder head. Subsequently, inserting said joint and bonded sand cores into respective firmly interconnected molds for molding said part of a housing shell of said turbocharger, for said manifold and said cylinder head, and filling molten metal into said molds and allowing solidification of said metal. After that, the integrally cast single piece of part of the housing shell of the turbocharger together with the manifold and the cylinder head is released and the cores are removed.
