Dynamic three-way catalytic mechanical arm automobile

Abstract

The invention discloses a dynamic three-way catalytic mechanical arm automobile. The automobile comprises an automobile body, a three-way catalytic device and an exhaust pipe cold end; the three-way catalytic device comprises an outer cover, a heat insulation pad, two filter screens, a honeycomb catalytic core body and multiple shape memory metal sheets; a catalytic chamber is formed among the heat insulation pad and the filter screen; the honeycomb catalytic core body is arranged in the catalytic chamber and is provided with multiple catalytic vent holes which are regularly arranged; the multiple shape memory metal sheets are correspondingly embedded in the multiple catalytic ventilation holes; the two surfaces of each shape memory metal sheet are coated with catalyst coatings; the shapememory metal sheets have wavy states and extension deformation states; and gaps are formed between wave crest positions of the metal sheets and the inner walls of the catalytic ventilation holes and between wave trough positions of the metal sheets and the inner walls of the catalytic ventilation holes. According to the automobile, the catalytic flux is dynamically adjusted by the aid of the shapechange of the shape memory metal sheets, so that a large amount of incomplete combustion alkane generated by an engine in the working process of a cooling machine is treated in time, and the pollution of automobile exhaust to the environment is effectively reduced.

Description

technical field [0001] The invention relates to a dynamic three-way catalytic mechanical arm automobile. Background technique [0002] The three-way catalytic converter is the most important external purification device installed in the exhaust system of automobiles. It can convert harmful gases such as carbon monoxide, hydrocarbons and nitrogen oxides from automobile exhaust into harmless gases through oxidation and reduction. Carbon dioxide, water and nitrogen, thereby reducing air pollution from vehicle exhaust. [0003] However, the existing three-way catalytic converter for vehicles lays the catalyst inside the ceramic catalytic core, which cannot adjust the flux of the catalytic core according to the working conditions of the automobile engine, resulting in a large amount of incomplete combustion of alkanes produced by the engine during cold engine operation. If it cannot be treated in time, it will be discharged into the atmosphere and seriously pollute the environme...
