Abstract

The invention belongs to the technical field of automobile exhaust emission, and specifically relates to an anti-clogging structure of a three-way catalytic converter, which includes a shell and a ceramic carrier. The shell includes a metal shell, and the inner wall of the metal shell is provided with an insulating interlayer. The inner side wall of the heat insulating interlayer is provided with an anti-corrosion coating, the left side of the housing is provided with an air inlet, and the top and bottom of the air inlet are respectively provided with a front pressure sensor and a front temperature sensor. The right side of the exhaust port is provided with an exhaust port, the top and bottom of the exhaust port are respectively provided with a rear pressure sensor and a rear temperature sensor, the front surface of the exhaust port is provided with a gas flow rate sensor, and the front surface of the housing A vibrating motor is provided, and a transmission rod is provided on the side wall of the inner cavity of the housing. Its structure is reasonable. During use, it is convenient to monitor the temperature and pressure of the intake air and the temperature and pressure of the exhaust gas. At the same time, the gas flow rate at the exhaust port can be detected. Prevent clogging.

Description

technical field [0001] The invention relates to the technical field of automobile exhaust emission, in particular to an anti-clogging structure of a three-way catalytic converter. Background technique [0002] Catalytic Converter (CatalyticConverter), also known as catalytic converter. The device is installed in the exhaust system of the car, and its role is to reduce most of the exhaust pollutants emitted by the engine. The three-way catalytic converter consists of a metal shell, a mesh bottom frame and a catalytic layer (containing precious metals such as platinum and rhodium), which can remove HC (hydrocarbons), CO (carbon monoxide) and NOx (nitrogen oxides) three 90% of the major pollutants (the so-called ternary refers to the chemical reaction that occurs when these three compounds are removed). When the exhaust gas passes through the purifier, the platinum catalyst promotes the oxidation of HC and CO to produce water vapor and carbon dioxide; the rhodium catalyst pro...
