Abstract
An exhaust gas purification device for a vehicle includes a tubular enclosure having a central axis, a purification member for exhaust gases housed in the tubular enclosure, an electric heating member housed in the tubular enclosure, and a power source electrically powering the electric heating member. The electric heating member comprises a heating plate made from an electrically conductive material extending in a plane substantially perpendicular to the central axis. The heating plate has a solid center and at least two branches, each branch extending in a spiral from the solid center to a free end located near the tubular enclosure. The heating plate is permeable to the exhaust gases and comprises a network of passages for the exhaust gas generating a turbulent flow of the exhaust gases through the heating plate.
