摘要： In an exhaust gas purification system provided with a denitration catalyst layer, a reducing agent oxidation catalyst layer is installed together; a reducing agent and air are supplied into the reducing agent oxidation catalyst layer at the time of catalyst regeneration of the denitration catalyst layer; a high-temperature oxidation reaction gas is produced by a reaction heat generated by an oxidation reaction of the reducing agent and the air in this reducing agent oxidation catalyst layer; and this high-temperature oxidation reaction gas is introduced into the denitration catalyst layer to heat the denitration catalyst, thereby recovering a denitration performance of the catalyst.

摘要： A reducing agent supplying device includes a reforming device, an obtaining section and a controller. The reforming device mixes fuel, which is a hydrocarbon compound, with air, and reforms the fuel by partially oxidizing the fuel with oxygen in the air. A reformed fuel is supplied into the exhaust passage as the reducing agent. The obtaining section obtains a physical quantity as a property index. The physical quantity has a correlation with property of the fuel that is supplied to the reforming device. The controller controls the reforming device according to the property index obtained by the obtaining section.

摘要： An exhaust pipe fuel injector capable of preventing fuel from remaining in a fuel supply system and thus capable of preventing the fuel supply system from being blocked due to carbonization of the fuel, is provided. The exhaust pipe fuel injector includes: a fuel injection nozzle that injects the fuel into an exhaust pipe; a supply pipe through which a mixed fluid of the fuel and air is supplied into the fuel injection nozzle; and a control unit. The control unit has a function of continuing combustion until no fuel remains in the inside of the supply pipe during regeneration of a diesel particulate filter.
