Abstract

The invention relates to a post-processing sensor module mounting structure. The structure comprises module fixing hoops, sensor inserts, a module base and a support, wherein the module fixing hoops penetrate through the module base and then fix the module base on an EGP (exhaust gas processor) casing; the support is fixed on the module base; the sensor inserts are fixed on the support. With the adoption of the technical scheme of the module base, the support, the module fixing hoops and the sensor inserts, modular assembly of post-processing sensors is realized, and a whole vehicle chassis harness is connected with the sensors by the aid of the sensor inserts. Besides, the structure can be mounted by surrounding an EGP by 360 degrees according to the whole vehicle arrangement space requirement, and the heat damage of the EGP to the sensor inserts can be reduced.

Description

technical field [0001] The invention belongs to the technical field of automobile exhaust gas treatment, in particular to an installation structure of a post-processing sensor module. Background technique [0002] With the emission upgrade to the National IV and National V stages, the aftertreatment system of light trucks is becoming more and more complex; the commonly used SCR (Selective Catalytic Reduction) technology route is widely used. Among them, EGP (exhaust gas processor) has multiple sensors such as: inlet exhaust gas temperature sensor, outlet exhaust gas temperature sensor and NOx (nitrogen oxide) sensor. [0003] Among them, the inlet exhaust temperature sensor and the outlet exhaust temperature sensor are used to monitor the exhaust temperature of the EGP, and the NOx sensor is used to monitor whether the NOx content in the exhaust gas meets the regulatory requirements. [0004] The sensors on the existing EGP are all arranged separately, or they are bundled a...
