Description

Mat for catalytic converter {MAT FOR CATALYTIC CONVERTER}

The present invention relates to a mat for a catalytic converter, and more particularly, protects the catalyst of the catalytic converter for reducing harmful components of the exhaust gas discharged from the engine, and at the same time, the exhaust gas flowing into the catalytic converter is discharged to the outside. It relates to a mat for a catalytic converter to prevent that.

In general, the exhaust gas discharged from the engine through the exhaust manifold is introduced into the catalytic converter through the exhaust pipe to be purified, and the noise is attenuated while passing through the muffler and released into the atmosphere.

Here, the catalytic converter serves to treat pollutants contained in the exhaust gas, and the catalyst carrier is provided inside the catalytic converter to purify harmful substances contained in the exhaust gas.

The material of the catalyst carrier is magnesium-silicate silicate having high heat resistance, the main component, and the shape of the catalyst carrier is formed so that a plurality of honeycomb-like passages are formed to pass the exhaust gas therebetween.

Since the ceramic honeycomb type catalyst carrier is weak to vibration and impact, a mat, which is a support of an elastic material such as a metal fiber, is usually provided between the shell and the catalyst carrier. Compensates for the expansion coefficient of the shell and absorbs mechanical stress.
