Abstract
The invention relates to rapid aging test equipment for a catalytic converter. The rapid aging test equipment comprises an all-around sealed container, a fuel injection nozzle, a sparking plug, a muffler assembly and a plurality of cordierite ceramic blocks, wherein the fuel injection nozzle and the sparking plug are installed in the container, the muffler assembly is connected to the container through a connection pipeline, and the cordierite ceramic blocks are arranged in the muffler assembly. The connection pipeline is provided with a urea nozzle. The fuel injection nozzle is connected to a fuel tank through a fuel pump. The urea nozzle is connected to a urea tank through a urea pump. The fuel injection nozzle sprays fuel in the fuel tank into the container, the sparking plug is ignited, and combusted fuel produces tail gas to simulate tail gas emission in the actual starting process of an automobile. Afterwards, the tail gas is mixed with urea sprayed out of the urea nozzle when flowing through the connection pipeline, wherein the tail gas is mainly composed of air, NOx and water vapor. Finally, the mixed gas reacts when flowing through through-holes in the cordierite ceramic blocks in the muffler assembly. By simulating a rapid aging test of the catalytic converter, the cost of actual vehicle tests is effectively lowered, and efficiency is enhanced.
