Engine exhaust purifier |
| abstract |
An HC adsorbent which adsorbs hydrocarbons in a predetermined low temperature region and discharges hydrocarbons in a temperature region higher than the lower temperature region is provided in an engine exhaust passage. A catalyst which oxidizes hydrocarbons in a predetermined high temperature region is provided downstream of the HC adsorbent. A heater for heating exhaust is provided upstream of the HC adsorbent. A control unit activates the heater when the exhaust temperature has risen to near the upper limit of the lower temperature region. Activation of the catalyst is thereby promoted, and the time until the catalyst starts oxidizing hydrocarbons discharged by the HC adsorbent is shortened. |
