Component e.g. exhaust manifold for exhaust system of e.g. motor car, has inner component with outer side and outer component with inside partially spaced from each other such that gap is formed between inner and outer components

摘要

The component (1) has a tubular inner component (2) and an outer component that surrounds the inner component. The inner component consists of a sheet metal structure and the outer component produces a casting structure by casting the inner component. The outer side of the inner component and inside of the outer component are partially spaced from each other such that gap (Z) is formed between the inner component and outer component. A thermal insulation material (4) is arranged in the gap. The inner component has several tubular elements (2.1,2.2). Independent claims are included for the following: (1) a method for producing a component for an exhaust system of a vehicle; and (2) an exhaust system of vehicle.
