Abstract

An exhaust system for an internal combustion engine is provided. The exhaust system includes an exhaust manifold receiving exhaust gas from a cylinder, an emission control device positioned downstream of the exhaust manifold, an electric heating device positioned in an exhaust line upstream of the emission control device and downstream of the exhaust manifold, the electric heating device including a frame at least partially surrounding a heating element, and an adjustment device configured to, during operation of the internal combustion engine, adjust the drag generated by the electric heating device in an exhaust gas flow through the exhaust line.
