摘要： An exhaust gas aftertreatment method may include a regenerating a diesel particulate filter normally, accumulating a time from a point that the diesel particulate filter starts to be regenerated, determining whether the diesel particulate filter enters into an abnormal regeneration condition or not according to a predetermined condition of an engine, and regenerating the diesel particulate filter according to the abnormal regeneration logic, if the accumulated time is within a predetermined time in a condition that the abnormal regeneration condition is satisfied and regenerating the diesel particulate filter according to the normal regeneration logic, if the accumulated time is out of the predetermined time. Accordingly, if the time elapses a predetermined time from a point that that the diesel particulate filter starts to be regenerated, although the vehicle enters into the idle condition or the over-run condition, the abnormal regeneration logic is not performed such that the fuel consumption is saved and the diesel particulate filter is safely regenerated.
摘要翻译：废气后处理方法可以包括通常从柴油机微粒过滤器开始再生的时刻累积柴油微粒过滤器，根据预定条件确定柴油机微粒过滤器是否进入异常再生状态的发动机，并且如果在满足异常再生条件并根据正常再生逻辑再生柴油机微粒过滤器的情况下累积时间在预定时间内，则根据异常再生逻辑再生柴油机微粒过滤器，如果累积时间超出预定时间。因此，如果从柴油机微粒过滤器开始重新生成的时刻经过了预定时间，则虽然车辆进入怠速状态或过度运行状态，但不执行异常再生逻辑，使得燃料消耗节省了柴油微粒过滤器的安全再生。
