Abstract: Insulation system for thermoacoustic insulation of a component to be insulated, such as an exhaust gas component, comprising a fiber molded part having a surface facing away from the component to be insulated, where the surface facing away is at least in part jacketed with a cladding, and having an insulation surface facing the component to be insulated, where the fiber molded part is applied to the component to be insulated such that at least one cavity is formed between a portion of the insulation surface of the fiber molded part and the component to be insulated.

Abstract: A turbine housing (1) of an exhaust-gas turbocharger (15) having a turbine volute (7) which is delimited by a metallic outer shell (8) and which has an inner wall (9); and a heat insulation layer (10) which is arranged on the inner wall (9) and which has a heat insulation core (6A, 6B) which, on its surface (12A, 12B) facing into a volute interior space (11), is covered by a first sheet-metal shell (3A, 3B). The heat insulation core (6A, 6B) is covered, on a surface (13A, 13B, 13?B) facing toward the inner wall (9), by a second sheet-metal shell (4A and 4B respectively).

Abstract: An insulating molded part for a hot gas conducting component, in particular an exhaust system of an internal combustion engine, is described, which exhibits increased mechanical strength by using an insulating fibrous tissue.

Abstract: A hot gas conducting component, in particular for an exhaust system of an internal combustion engine, is described. To improve the insulation effect, an insulation to which heat-reflecting and/or heat-absorbing pigments are added is arranged at the component.
