EXHAUST GAS TREATMENT DEVICE FOR DIESEL ENGINE

摘要

An exhaust gas treatment device for a diesel engine, capable of smoothly starting the generation of a combustible gas (4) and provided with a small-sized combustible gas generator (1). A core member (15) is fitted in the center portion of an annular wall (14) to form an air-fuel mixing chamber (12) between the inner peripheral surface (16) of the annular wall (14) and the outer peripheral surface (18) of the core member (15). An air-fuel mixture gas (23) in the air-fuel mixing chamber (12) is adapted to be supplied from the end of the air-fuel mixing chamber (12) to a combustible gas generating catalyst (13) to a portion near the center thereof. A heater (25) is used as the core member (15), the heat dissipating outer peripheral surface (26) of the heater (25) is exposed to the air-fuel mixing chamber (12), and heat is dissipated directly from the heat dissipating outer peripheral surface (26) of the heater (25) to the air-fuel mixing chamber (12) when starting the generation of the combustible gas (4).
