Problems solved by technology

However, in the actual assembly process, because the Euro VI post-processing system includes 4 temperature sensors, which are the temperature sensor before the DOC, the temperature sensor after the DOC, the temperature sensor after the DPF, and the temperature sensor after the SCR, it is easy to be sequentially connected during installation. Due to the faulty problem, the DPF cannot be regenerated normally, and the urea cannot be injected normally; at the same time, because the wiring harness of each sensor and actuator is not unified, it is easy to cause the wiring harness to be burned at high temperature; and the DOC in the existing post-processing system - The DPF assembly and the SCR assembly are designed to be connected together, and the two cannot be separated, resulting in poor adaptability to the layout of the vehicle, strict requirements on space, and a single suitable model

Abstract

The invention discloses a DOC-DPF-SCR assembly device. The device comprises a DOC-DPF assembly and an SCR assembly, and the DOC-DPF assembly is detachably connected with the SCR assembly; in the actual assembling, a connecting piece matched with a mounting space of a vehicle body is added between the DOC-DPF assembly and the SCR assembly to adapt to different automobile assembly. The DOC-DPF-SCR assembly device can be designed and installed according to the space of the whole vehicle so as to adapt to various types of vehicle types, and the device is diversified in installation form. Therefore, the DOC-DPF-SCR assembly device is provided, the universality of the DOC-DPF-SCR assembly is guaranteed, and the problem in the field at the present stage is solved.

Description

technical field [0001] The invention relates to a diesel engine aftertreatment system, more specifically, to a DOC-DPF-SCR assembly device. Background technique [0002] DOC-DPF-SCR assembly of diesel engine is a collection of oxidation catalyst, diesel particulate filter and selective catalytic reduction system, which is used to treat the exhaust gas of diesel engine. [0003] As far as the existing technology is concerned, the traditional DOC-DPF-SCR device only integrates the temperature sensor seat, the nitrogen and oxygen sensor seat, the urea nozzle seat, etc., and does not install the corresponding sensors, accessories, and wiring harnesses. Assembled by the manufacturer. However, in the actual assembly process, because the Euro VI post-processing system includes 4 temperature sensors, which are the temperature sensor before the DOC, the temperature sensor after the DOC, the temperature sensor after the DPF, and the temperature sensor after the SCR, it is easy to be ...
