It is the most widely used and effective method for purifying the air outside the machine. It is a reactor which adopts solid catalyst, when the tail gas of internal combustion engine of car is passed through, the harmful components of CO, HC and NOx in the tail gas can be chemically reacted and converted into harmless CO2, H2O and N2. The three-way catalytic reactor has obvious effect of purifying and treating the pollution gas discharged by the internal combustion engine, but has certain defects. The device can be only used for an electronic injection gasoline internal combustion engine and cannot be used for a carburetor gasoline internal combustion engine and a diesel internal combustion engine; secondly, because the three-way catalytic reactor uses a solid catalyst, aerosol-state substances (pollutants such as lead compounds, smoke dust, oil mist and the like) in the tail gas of the internal combustion engine cannot be purified, and a catalyst carrier is blocked and covered on the surface of the catalyst, so that the three-way catalytic reactor cannot work and needs to be replaced; thirdly, the emission of a large amount of carbon dioxide is important for 'greenhouse effect'.
