Title:
DIESEL ENGINE EXHAUST GAS AFTERTREATMENT SYSTEM AND HEATING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2021/203641
Kind Code:
A1
Abstract:
A diesel engine exhaust gas aftertreatment system, comprising an exhaust gas aftertreatment package (1), a power supply (2), a control unit (3), and a coil heating device (4). The exhaust gas aftertreatment package (1) comprises an exhaust gas inlet (11), an exhaust gas outlet (12), and a metal plate (13) to be heated between the exhaust gas inlet (11) and the exhaust gas outlet (12); the power supply (2) is connected to the control unit (3), and supplies the control unit (3) with power required for the operation thereof; the control unit (3) is connected to the coil heating device (4), and the coil heating device (4) is installed on said metal plate (13); when said metal plate (13) needs to be heated, the control unit (3) transmits an alternating voltage signal to the coil heating device (4), so that the coil heating device (4) generates an eddy current effect on said metal plate (13), so as to increase the temperature of said metal plate (13).
