Title:

EXHAUST GAS TREATMENT DEVICE FOR DIESEL ENGINE

Document Type and Number:

WIPO Patent Application WO/2011/125438

Kind Code:

A1

Abstract:

An exhaust gas treatment device for a diesel engine, capable of smoothly starting the generation of a combustible gas (4) and configured so that a combustible gas generator (1) is compact. A core member (15) is fitted in the center part 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 supplied from the dead end of the air-fuel mixing chamber (12) to the portion of a combustible gas generation catalyst (13) which is located near the center thereof. A heater (25) is used as the core member (15), and the heat radiating outer peripheral surface (26) of the heater (25) is exposed to the air-fuel mixing chamber (12). When the generation of the combustible gas (4) is started, heat is directly radiated to the air-fuel mixing chamber (12) from the heat radiating outer peripheral surface (26) of the heater (25).
