AUTOMOBILE EXHAUST GAS DISCHARGE CONTROL METHOD

摘要

An automobile exhaust gas discharge control method, comprising: obtaining an exhaust pressure value at an automobile engine exhaust pipe outlet (S101); when the exhaust pressure value reaches a preset value, detecting exhaust gas of an automobile exhaust gas purifier outlet, and obtaining the types and amounts of harmful gases in the exhaust gas (S102); determining whether excessive harmful gases are present in the exhaust gas according to the types and amounts of the various harmful gases (S103); if yes, issuing a secondary absorption command, opening a valve of an automobile second purifier, controlling the exhaust gas to pass through the automobile second purifier, and implementing secondary absorption treatment on the automobile exhaust gas (S104). The automobile exhaust gas discharge control method determines whether to perform the secondary treatment on the automobile exhaust gas via the exhaust pressure value and the types and amounts of the harmful gases, and prevents environmental pollution by the exhaust gas.
