Abstract

The invention provides a pressure difference measuring system of an automobile postprocessor. The pressure difference measuring system comprises a front gas extracting pipe, a rear gas extracting pipe and a pressure sensor. The front gas extracting pipe comprises a first steel pipe and a first hose, and the rear gas extracting pipe comprises a second steel pipe and a second hose. One end of the first steel pipe of the front gas extracting pipe is connected with a gas feeding end of a postprocessor, the other end of the first steel pipe is connected with the first hose, and the other end of the first hose is connected with the pressure sensor; and one end of the second steel pipe of the rear gas extracting pipe is connected with a gas discharging end of the rear processor, the other end of the second steel pipe is connected with the second hose, and the other end of the second hose is connected with the pressure sensor. The pressure difference measuring system of the automobile postprocessor is reliable in pressure difference measuring pipeline systems, good in pressure sensor measuring accuracy and capable of performing pressure signal acquisition on the postprocessor.

Description

technical field [0001] The invention relates to an automobile tail gas treatment system, in particular to a pressure difference signal acquisition system for an automobile post-processing system. Background technique [0002] With the development of the automobile industry, the requirements for automobile emissions are getting higher and higher, and many vehicles have added exhaust after-treatment systems to reduce the adverse impact of automobile exhaust on the environment. Therefore, the pressure signal acquisition and fault diagnosis of the automotive post-processor system are particularly important, but the existing post-processor system lacks a real-time monitoring structure to monitor pressure, temperature, etc. In addition, when the post-processor system monitors data indicators such as pressure and temperature in real time, a pressure sensor needs to be installed for pressure monitoring. The general pressure sensor has poor tolerance to temperature, so it is necessar...
