    • PURPOSE: A method for disposing exhaust gas is provided to precisely detect the damage of a diesel particulate filter using differential pressure between the front and the rear end of the diesel particulate filter. CONSTITUTION: A method for disposing exhaust gas includes: a step of calculating the model amount of a sensor collecting particulate collected by a particulate sensor(140) under the normal condition of a diesel particulate filter(130) based on a condition for engine driving and the variation of the condition; a step of calculating the actual amount of the sensor collecting particulate attached to the particulate sensor using the actual signal of the particulate sensor; and a step of the status of the diesel particulate sensor by comparing the model amount of the sensor collecting particulate and the actual amount of the sensor collecting particulate.
    • 目的:提供废气排放的方法,以便通过柴油机微粒过滤器的前端和后端之间的差压来精确检测柴油颗粒过滤器的损坏。 构成:排气处理方法包括:基于发动机驱动条件,计算在柴油机微粒过滤器(130)的正常状态下由颗粒传感器(140)收集的颗粒收集颗粒的模型量的步骤; 条件的变化; 使用颗粒传感器的实际信号计算附着到颗粒传感器的传感器收集颗粒的实际量的步骤; 以及通过比较传感器收集颗粒的模型量和传感器收集颗粒的实际量来确定柴油颗粒传感器的状态的步骤。
