Abstract: <P>PROBLEM TO BE SOLVED: To solve a problem where HC which is easily exhausted after starting because HC starts to be detached from a HC trap before a three way catalyst reaches an active temperature after cold starting of an engine in an engine exhaust gas purifying system using a HC trap catalyst.  <P>SOLUTION: One or more slit is formed at the downstream of a carrier traversing a cell of the honeycomb carrier, and an HC trap agent is carried so as to increase a carrying amount at the upstream of the carrier. The carrying amount is increased at the upstream of the carrier which easily increases in temperature so that the heat capacity is increased, and the HC trap agent is restrained in temperature increase. The slit restrains the heat transmission into the carrier downwards, also delaying increase in temperature at the downstream of the carrier to make increase the captured amount of the HC as a whole. The treating efficiency on HC detaching is also increased by the delay of increase in temperature. Exhaust gas introduced into the cell generates disturbance in a slit part, and increases the chance of contacting with the HC trap agent by the exhaust gas to increase HC trap efficiency.  <P>COPYRIGHT: (C)2004,JPO
