Abstract
A catalytic device is disclosed, in which a catalytic layer is electrically heated and activated. In one form, the quantity of the catalytic layer is greater near a gas outlet than near a gas inlet of the device. In another form, the catalytic layer is disposed only near the gas outlet. The catalytic layer can be quickly activated so as to promote purification of exhaust emissions immediately following the ignition.
