Title:
AUTOMOBILE EXHAUST GAS PURIFICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2017/193673
Kind Code:
A1
Abstract:
An automobile exhaust gas purification method, comprising: obtaining an exhaust pressure value at an automobile engine exhaust pipe outlet; when the exhaust pressure value reaches a preset value, detecting exhaust gas of an automobile exhaust gas purifier outlet; according to a detection result, determining whether a nitrogen oxide emission amount in the automobile exhaust gas exceeds a threshold value; if yes, opening a valve of an automobile second purifier, discharging the automobile exhaust gas to the automobile second purifier, and ionising nitrogen oxides in the automobile exhaust gas via high energy electron beam irradiation means, so as to implement secondary absorption treatment on the automobile exhaust gas. The method determines whether to perform the secondary treatment on the automobile exhaust gas via the exhaust pressure value and the nitrogen oxide emission amount, and prevents environmental pollution by the exhaust gas.
