Abstract: A gel which contains a component of a catalyst is prepared. The gel and another gel are arranged in layers at a position which faces open ends of exhaust flow passages of a wall flow-type particulate filter. Next, a pusher is used to push and pack the gel and other gel through the open ends to the insides of the exhaust flow passages. Next, the particulate filter is made to dry to thereby make the partition walls carry the catalyst on their surfaces or in their micropores.

Abstract: An exhaust purification device for an internal combustion engine is provided with an NOx adsorbent for adsorbing NOx in exhaust gas and an NOx purifying catalyst for purifying NOx in exhaust gas, which are arranged in an engine exhaust passage. An electric heater is provided for raising the temperature of the NOx adsorbent. When a signal requesting startup of an internal combustion engine is issued, the device starts to supply electric power to the electric heater before the internal combustion engine completely warms up, and supplies the electric heater with a quantity of electric power making the temperature of the NOx adsorbent equal to or higher than the moisture desorption temperature but lower than the NOx desorption temperature.
