Abstract

The invention discloses an EGR exhaust gas treatment device. The EGR exhaust gas treatment device comprises a first waste gas exhaust header pipe, a first waste gas exhaust branch pipe, a first wastegas recovery branch pipe, a first EGR control valve, a first vortex front control valve and a turbocharger. The gas inlet end of the first waste gas exhaust header pipe is connected with the gas outlet end of an engine. The gas inlet end of the first waste gas exhaust branch pipe and the gas inlet end of the first waste gas recovery branch pipe are both connected with the gas outlet end of the first waste gas exhaust header pipe. The gas outlet end of the first waste gas exhaust branch pipe is connected with the turbocharger. The gas outlet end of the first waste gas recovery branch pipe is connected with the gas inlet end of the engine. The first EGR control valve is installed on the first waste gas recovery branch pipe. The first vortex front control valve is installed on the first wastegas exhaust branch pipe. The invention further discloses a car comprising the EGR exhaust gas treatment device.

Description

technical field [0001] The invention relates to the technical field of engine exhaust gas recirculation, in particular to an EGR exhaust gas treatment device. The invention also relates to an automobile comprising an EGR exhaust treatment device. Background technique [0002] In recent years, automobile exhaust pollution and CO 2 The damage to the earth's ecological environment and the greenhouse effect caused by emissions are becoming more and more serious. Cars with good pollution discharge and low fuel consumption rate can not only alleviate the impact of climate warming and destruction of ecological environment balance caused by the global greenhouse effect. In order to reduce environmental pollution, EGR (Exhaust Gas Recirculation, Exhaust Gas Recirculation) is to reintroduce the exhaust gas from the engine into the intake pipe and mix it with fresh gas before entering the combustion chamber for combustion, which can effectively reduce engine NOX emissions and is wide...
