Overhigh temperature to the influence of the catalytic converter

* Reduce the pressure to the cushion
* Reduce the intensity and rigidity of metal shell
* Increase the clearance between metal shell and ceramic substrate, aggravate the distortion of metal shell
* Increase the damage of the cushion, shorten the working life

Designing of the substrate of catalytic converter

* Designing principle of the substrate shape.
1.Exert catalyst’s highest efficiency.
2.Transverse temperature of the substrate is smallest.
3.Make hermetic pressure distribute evenly.
* Length of the substrate 76mm-152mm.
* Honeycomb wall thickness of the substrate 0.1-0.2mm .

Function of insulating mat

* Function of insulating mat

* Fixation of crispy ceramic substrate

* Amortizing fission due to different heating inflation coefficient of metal can and ceramic carrier

* Airproof and preventiing waste gas leak

* Heatproof and avoiding overheating of the shell

* Sound insulation and noise reduction

* Protecting ceramic carrier away from effecting by the out force and shock

* Excellent airproof performance and ensuring all harmful gas to pass through catalyst carrier fully and reaching high purification effect
