Abstract

See full text

A method for producing a gasoline engine exhaust gas system having a particulate filter includes using at least one spacer for positioning at least two components provided for the passage of exhaust gas from the engine. The spacer includes ash-forming constituents. The method then includes permanently connecting the components, and burning the spacer element during a first heating up of the exhaust gas system, thereby releasing the ash-forming constituents and depositing the ash-forming constituents on the particulate filter. An exhaust gas system of a gasoline engine also is provided in a state before a first heating up of the exhaust gas system. The exhaust gas system includes a burnable spacer element between two exhaust gas system components that are provided for the passage of exhaust gas. The burnable spacer elements include ash-forming constituents.
