Abstract
A turbocharger heat shield is disposed around a turbocharger turbine housing and comprises first and second heat shield members each having a wall structure that is generally semi-cylindrical in shape. The heat shield members are removably attached with one and include axially opposed openings, and a radial opening, to accommodate passage of other turbocharger components therethrough. A third heat shield member may be included to cover a further element of the turbocharger. One or more tabs project from an edge of the first or second heat shield member to register with an adjacent edge of the other member to facilitate alignment, engagement and/or attachment between the two members. An insulating material can be interposed between the heat shield and the turbocharger housing and, in a preferred embodiment, is attached to the heat shield.
