Abstract

The invention is suitable for the technical field of automobile exhaust treatment, and provides an automobile exhaust aftertreatment system and an automobile, and the method comprises the steps that breathable carriers used for absorbing water are arranged in all exhaust treatment devices of an exhaust pipeline in the automobile exhaust aftertreatment system, and the carriers are used for absorbing water drops in the exhaust pipeline. The automobile exhaust can penetrate through a carrier and can be dehydrated, so that the time for re-evaporating water in an automobile post-treatment system is shortened, a sensor of the automobile post-treatment system can be heated to the working temperature of the sensor in advance, and the dew point time is shortened.

Description

technical field [0001] The invention belongs to the technical field of automobile exhaust gas treatment, and in particular relates to an automobile exhaust gas aftertreatment system and an automobile. Background technique [0002] Sensors such as oxygen sensor, nitrogen oxygen sensor, PM sensor (that is, particulate matter sensor) are one of the most critical sensors in the exhaust pipe of the automobile exhaust aftertreatment system. At present, the "measuring unit", the core component of the sensor in the automobile exhaust after-treatment system, needs to be self-heated to a certain temperature for measurement in order to produce accurate measurement results. However, if small water droplets are generated in the exhaust emissions of automobiles, when the small water droplets encounter the hot core component "measuring unit", the core component "measuring unit" will cause the "measuring unit" to rupture and fail due to thermal expansion and contraction. [0003] At presen...
