[0001] The utility model relates to the technical field of gas purification equipment, in particular to a three-way catalytic converter structure for a supercharged engine. Background Art

[0002] A supercharged engine is a technology that increases the gas density in the cylinder by increasing the air pressure in the engine intake duct. It compresses more air into each cylinder, so that more fuel can be burned during each combustion process, thereby generating a greater power output. The supercharged engine can be achieved by mechanical or electrical means. This technology is usually used to improve the power and efficiency of automobiles or other internal combustion engines. A three-way catalytic converter is a device used to reduce the emissions of harmful gases in vehicle exhaust. It is usually installed in the exhaust system of an automobile and is mainly used to reduce the emissions of carbon monoxide, nitrogen oxides, and hydrocarbons in the exhaust. The three-way catalytic converter works by converting these harmful gases into relatively harmless substances such as water vapor, oxygen, and nitrogen. This technology can effectively reduce the environmental pollution of automobile exhaust and is an important part of the modern automobile emission control system.

This three-way catalytic converter is not convenient to preheat to improve the catalytic efficiency of the catalyst, reducing the gas conversion efficiency;

[0006] This three-way catalytic converter is not convenient to judge whether the three-way catalytic converter is working properly by monitoring the oxygen concentration at the output end, reducing the convenience when using this three-way catalytic converter. Content of the Utility Model
