Engine vent gas catalytic cleaner activation evaluating system

Abstract

An engine exhaust catalyzed purifier activity evaluation system comprises a gas distribution subsystem, a temperature control subsystem, a reaction subsystem, a gas analysis subsystem, and a data acquisition and control subsystem. An output end of the gas distribution subsystem is connected with the reaction subsystem, the gas analysis system, the temperature control system and the reaction subsystem respectively. The reaction subsystem is connected with the gas analysis subsystem. The data acquisition and control subsystem is connected with the gas distribution subsystem, the reaction subsystem, the temperature control subsystem and the gas analysis subsystem. As a high-precision flow controller is used to collocate a simulated exhaust gas as a gas source, the catalyst can carry out an activity evaluation experiment in the artificially-controllable atmosphere. The system is provided with the stable gas source, the good repeatability, the high automation, and the precise temperature control, and can realize the flexible control of different temperature rising speeds at a plurality of sections. An exhaust analyzer can measure the concentration of gas in the front or back of the catalyst. The system is provided with the function of ignition temperature characteristic experiment, air-fuel ratio characteristic experiment and air-speed characteristic experiment simultaneously or respectively.

Description

technical field [0001] The invention relates to an evaluation system. In particular, it relates to a catalyst that can conduct activity evaluation experiments in an artificially controllable atmosphere environment. During the experiment, the gas source is stable, the repeatability is good, the system is highly automated, the operation is simple and convenient, and it has high experimental accuracy and reliability. A comprehensive engine exhaust catalytic converter activity evaluation system. Background technique [0002] With the extensive use of vehicles, the pollution to the environment is becoming more and more serious. At present, installing a catalytic converter in the vehicle exhaust system to reduce the emission of polluting gases in the exhaust gas is the main solution. The purification rate of the catalytic converter needs to be evaluated. The catalytic converter activity evaluation test device is necessary in the production, inspection and application process of ...

AI Technical Summary

Problems solved by technology

[0003] The original catalytic converter activity evaluation experiment used engine exhaust as the gas source and the full-scale catalytic converter used by the engine as the test device to be evaluated. Due to the difficulty in controlling the engine exhaust components and the poor repeatability of the gas source environment, the catalytic converter activity The comparability between the evaluation data is poor, and the activity of the catalytic converter cannot be evaluated fairly
