摘要:
An object of the present invention is to suppress a reduction in a NOx purification ratio accompanying filter regeneration processing in an exhaust gas purification system for an internal combustion engine that includes a filter carrying an SCR catalyst. In the present invention, the temperature of the filter is increased following completion of the filter regeneration processing by increasing the temperature of exhaust gas discharged from the internal combustion engine, and in so doing, HC adhered to the filter is removed.
摘要:
In an exhaust gas purification system for an internal combustion engine provided with a filter supporting an SCR catalyst, the present invention is intended to suppress HC and CO from being discharged to the outside at the time of the execution of filter regeneration processing, and to carry out the filter regeneration processing in an efficient manner. In the present invention, a post-catalyst having an oxidation function is arranged in an exhaust passage at the downstream side of the filter. Then, when the temperature of the post-catalyst is lower than a predetermined activation temperature at the time the execution of the filter regeneration processing is requested, the temperature of the post-catalyst is raised by carrying out control of raising the temperature of the exhaust gas discharged from the internal combustion engine, and control increasing the flow rate of the exhaust gas, before the execution of the filter regeneration processing.

A method of manufacturing a semiconductor device having a p-type field effect transistor and an n-type field effect transistor includes the steps of: forming an interface insulating layer and a high-permittivity layer on a substrate in the stated order; forming a pattern of a sacrifice layer on the high-permittivity layer; forming a metal-containing film containing metal elements therein on the high-permittivity layer in a first region where the sacrifice layer is formed and a second region where no sacrifice layer is formed; introducing the metal elements into an interface between the interface insulating layer and the high-permittivity layer in the second region by conducting a heat treatment; and removing the sacrifice layer by wet etching, wherein in the removing step, the sacrifice layer is etched easily more than the high-permittivity layer. With this configuration, the semiconductor device excellent in reliability is obtained.
