Abstract: An improved combustion and anti-pollution device for a motor vehicle having an internal combustion engine is shown in which the device reaches optimal operating temperature and thus maximum effectiveness almost at the same instant as the starting of the vehicle. In an embodiment of the pollution control transformer of the present invention, the basic components include a casing, a rod, a coil, an iron disk, a disk-shaped permanent magnet, and components for controlling the operating temperature of the coil. The components for controlling the operating temperature of the coil can be active heat control components, which include a heating filament, and passive heat control components, which include heat insulation materials such as silicon fiber resin materials surrounding the coil of the device.
