Three-way catalyst temperature control protection support

Abstract

The invention discloses a three-way catalyst temperature control protection support. The three-way catalyst temperature control protection support comprises a support body. The support body comprises a center installation portion, an upper installation portion, a lower installation portion, a left installation portion and a right installation portion, wherein the upper installation portion, the lower installation portion, the left installation portion and the right installation portion are fixedly and respectively connected with the center installation portion. An observation opening is formed in the center installation portion. A first groove is formed in the lower installation portion. A temperature sensor is installed in the first groove. A fan is arranged on the inner wall of the left installation portion. A second groove is formed in the right installation portion. A controller is arranged in the second groove. The symmetric portions of the left installation portion and the right installation portion are respectively provided with a three-way catalyst installation hole. The three-way catalyst temperature control protection support has the advantages of being simple in structure, convenient to install, low in machining cost and capable of increasing the installation strength of a three-way catalyst, adjusting the operation temperature of the three-way catalyst, making the three-way catalyst work within the best temperature range and guaranteeing the use safety.

Description

technical field [0001] The invention belongs to the technical field of auto parts, in particular to a three-way catalytic converter temperature control protection bracket. Background technique [0002] The three-way catalytic converter is the most important external purification device installed in the automobile exhaust system. It can convert harmful gases such as carbon monoxide, hydrocarbons and nitrogen oxides emitted by automobile exhaust into harmless gases through oxidation and reduction. Carbon dioxide, water and nitrogen. [0003] At present, most of the three-way catalytic converters are catalyst carriers formed of honeycomb ceramics inside, which are easily broken after collision, which will block the catalytic converter and exhaust system; moreover, the three-way catalyst must react at a minimum of 250 ° C, and the temperature is too high. When the temperature is low, the conversion efficiency drops sharply, and the catalyst's activation temperature (optimum wor...

AI Technical Summary

Problems solved by technology

There are many disadvantages in the above method: 1. The installation of the protective bracket and the insulation belt and the heat insulation board are cumbersome to operate, the processing cost is high, the mutual fault tolerance rate is low, and the stability is poor; 2. The insulation belt and the heat insulation board can only provide three-way catalytic However, when the temperature of the three-way catalytic converter is too low, the conversion efficiency will drop sharply, and the insulation belt and heat insulation board will prevent the heating speed of the three-way catalytic converter when it starts to work, which is not conducive to the operation of the three-way catalytic converter.
