Abstract
A system and method is provided in which a turbocharger includes a heat shield wall that is formed together with the bearing housing as a unitary structure. The wall can extend from a main body portion of the bearing housing in a generally radially outward direction. The wall can be spaced from the main body and attached by a plurality of ribs such that chambers are defined therebetween. A circumferential passage can extend through the bearing housing to permit fluid communication between the chambers and outside of the bearing housing. In this way, a fluid outlet from the chambers is provided. As a result of such an arrangement, the need for a separate heat shield is eliminated, which can facilitate the assembly process and special attachment methods associated with a separate heat shield.
