[Industrial applications]

 The present invention relates to a harmful exhaust gas reducing apparatus capable of reducing harmful substances such as nitrogen oxides, carbon monoxide and hydrocarbons contained in exhaust gas generated from an internal combustion engine such as an automobile engine or a boiler.

[0002]

[Prior art]

 In recent years, exhaust gas regulations have been tightened in order to prevent environmental deterioration due to harmful substances contained in exhaust gas discharged from internal combustion engines such as automobile engines or combustion chambers of boilers. Therefore, conventionally, for example, a turbocharger has been attached to an automobile engine. This is to drive the turbocharger by exhaust force and forcibly send air to the engine to increase combustion efficiency, improve horsepower and improve fuel efficiency, and reduce harmful substances in exhaust gas. However, it is still insufficient to reduce the harmful substances. In addition to these, it was considered to add chemicals to the fuel oil, to arrange a magnet in the fuel tank, to connect a container with a built-in ceramic to the fuel pipe, but in either case, it is sufficient. I couldn't produce any results.
