摘要： PROBLEM TO BE SOLVED: To solve such a problem that the initial pressure losses of filters for purifying particulates PM in exhaust gas are different in individual solid bodies and so dispersion occurs in the accumulation amount of the PM when the regeneration of the PM is stared at a PM regeneration starting differential pressure, making it impossible to uniformly regenerate it in all filters. SOLUTION: At least once PM regeneration control is performed in a preset period after the initial condition of the filter and the exhaust loss of the filter is found together with the PM regeneration control, and the initial pressure loss is calculated in accordance with this value. A value, which is obtained by adding a pressure loss value in the accumulated state of the amount of PM capable of being purified with a predetermined fuel addition amount to the initial pressure loss, is a differential pressure in PM regeneration starting pressure. By adding a predetermined fuel amount at the time when the differential pressure in PM regeneration starting pressure is reached, the PM accumulated on the filter can be uniformly regenerated.

摘要： PROBLEM TO BE SOLVED: To provide a technology capable of increasing opportunities to carry out the control for regeneration of an NOx catalyst poisoned by sulfur and also suppressing the deterioration of the catalyst caused by sulfur poisoning. SOLUTION: This exhaust emission control device is provided with an NOx absorbent which absorbs NOx in an exhaust gas when the air/fuel ratio of the inflowing exhaust gas is lean and releases the absorbed NOx when the above air/fuel ratio is theoretical or rich, and a control means for carrying out the temperature elevation control of the NOx absorbent and the control of regenerating the catalyst poisoned by sulfur. Since the control means releases oxygen (O2 ) stored in the NOx absorbent by lowering the air/fuel ratio in the exhaust gas when the temperature elevation control is carried out before the start of regeneration control of the poisoned NOx absorbent, the delay thereof is eliminated. The NOx absorbent may be carried on a filter capable of temporarily capturing particulates.
