    摘要： A reducing agent supplying device is for a fuel combustion system that includes a NOx purifying device with a reducing catalyst arranged in an exhaust passage to purify NOx. The reducing agent supplying device supplies a reducing agent into the exhaust passage upstream of the reducing catalyst. The reducing agent supplying device includes an air pipe, a vaporizing container, an injector, a heating member and a mixing plate. The air pipe defines an air passage therein. The vaporizing chamber is connected to the air pipe. The vaporizing container defines a vaporizing chamber therein that branches off from the air passage. The injector injects liquid hydrocarbon compound as a reducing agent. The heating member is disposed in the vaporizing chamber. The heating member heats and vaporizes the reducing agent. The mixing plate is connected to the heating member. The mixing plate extends from the vaporizing chamber into the air passage.

    摘要： In an internal combustion engine, an exhaust purification catalyst: (13), particulate filter (14), and hydrocarbon feed valve (15) are arranged in an engine exhaust passage. A low pressure exhaust gas recirculation system (LPL) is provided for making the exhaust gas downstream of the particulate filter (14) recirculate. If hydrocarbons are injected from the hydrocarbon feed valve (15), the carbon dioxide which is produced in the exhaust purification catalyst (13) is recirculated and the air-fuel ratio of the exhaust gas which flows into the exhaust purification catalyst (13) temporarily drops. At the time of regeneration of the particulate filter (14), hydrocarbons are injected from, the hydrocarbon feed valve (15) so as not to overlap with this temporary drop of the air-fuel ratio.

    摘要： A control device for an internal combustion engine which does not require fitting of a feed forward term on an occasion of calculation of a fuel amount to be supplied at a time of temperature raising control is provided. According to the present embodiment, by feed forward control using a steady-state DPF model and a steady-state CCO model, a basic amount (feed forward term) of a fuel amount Qinj that is added from a fuel injector 20 in the temperature raising control can be calculated. Namely, the feed forward term can be calculated without depending on a control map. If the feed forward term can be calculated without depending on the control map, fitting of the feed forward term with use of the controlling map is not required.

    摘要： The present invention is intended to provide a technique which serves to suppress unburnt HC from being discharged to a downstream side, when fuel is injected from a fuel supply valve for removing clogging thereof. The present invention is provided with a fuel supply valve that supplies fuel to an exhaust passage of an internal combustion engine, and an ignition unit that ignites the fuel supplied from the fuel supply valve, wherein in cases where there is a possibility that clogging may occur in an injection hole of the fuel supply valve, fuel for removal of clogging is injected from the fuel supply valve. An amount of the fuel to be injected from the fuel supply valve for removing clogging thereof is an amount of fuel which is able to be combusted by being ignited by means of the ignition unit.
