CATALYTIC CONVERTER WITH MULTI-ARRANGEMENT TYPE FOR DIESEL ENGINE

摘要

A multi-arrangement type catalytic converter for a diesel engine is provided to maximize a purification efficiency of the converter by controlling the flow of exhaust gas using a solenoid valve, which is interlocked with a temperature sensor. A multi-arrangement type oxidation/reduction catalytic converter for a diesel engine comprises a fluid path(20) for discharging exhaust gas. An inner tube(28) is installed in the middle of the fluid path. A high temperature valve(27) is installed on an inner wall of the inner tube and the fluid path. An electric heater(29) is installed on the inner tube. A fourth oxidation catalyst(34) is installed at a rear side of the electrical heater in the inner tube. An oxidation/reduction catalyst complex(36) is installed at a rear side of the inner tube in the fluid path. A filtering apparatus(37) for exhaust gas is installed at a fluid exhausting end of the oxidation/reduction catalyst complex.
