Exhaust emission purifier of internal combustion engine |
| abstract |
An electronic control unit estimates the amount of sulfur accumulated in a filter for purifying PM and NOx based on the operating state of an engine. When an estimated value is equal to or greater than a predetermined determination value, a first regeneration procedure is executed, in which sulfur is released from the filter by raising the temperature of the filter up to a first predetermined temperature and lowering the exhaust air-fuel ratio. When predetermined conditions are met the second regeneration procedure is executed separately from the first regeneration procedure. In the second regeneration procedure, sulfur is completely released from the filter by raising the temperature of the filter up to a temperature higher than the first temperature and lowering the exhaust air-fuel ratio. The estimated value is reset upon completion of the second regeneration procedure. |
