Quickly understand the advantages and disadvantages of ceramic carrier

We are all aware that the installation of the three-way catalytic converter is crucial in reducing harmful emissions from automobile exhaust systems.

This external purification device plays a vital role in gasoline and diesel engines, serving as an integral component of modern vehicle emission control systems. Its primary function is to convert detrimental gases like carbon monoxide, hydrogen, and nitrogen oxides into harmless substances such as carbon dioxide, water, and nitrogen. Consequently, this significantly mitigates the release of harmful pollutants into the environment while safeguarding human health.

In this purification device, the carrier assumes a pivotal role. The ceramic carrier material is commonly employed alongside metal carriers within the honeycomb structure of the three-way catalytic converter. Now let us delve into its characteristics and assess its advantages and disadvantages.

The ceramic carrier is typically white, although it can exhibit other colors when the precious metal catalyst is applied to the ceramic substrate, resulting in a color change. The cross-sectional shape of the ceramic carrier can vary, including circular, racetrack-shaped, oval-shaped, and customized special shapes based on customer requirements. This design flexibility aims to accommodate different vehicle models' needs. Ceramic carrier three-way catalytic converters are widely utilized in most factory vehicles available in the market.

Advantages of ceramic carriers include:

- Production flexibility for different core structures based on user specifications.

- Customizable designs tailored to meet various motor vehicle requirements.

- Compatibility with multiple catalyst active components.

- Excellent cold-start performance characterized by low ignition temperatures and rapid heating.

- Minimal gas resistance resulting in high conversion efficiency.

- Cost-effectiveness attributed to thin hole walls coupled with low resistance yet high compressive strength.

Disadvantages of ceramic carrier:

However, the ceramic carrier also has drawbacks as it is susceptible to carbon deposition and poisons. Over time, this can lead to catalytic blockage, necessitating regular cleaning or replacement. Moreover, cleaning itself may cause some damage. Therefore, in order to fundamentally solve the problem, replacing it with a new one is necessary to a certain extent. Additionally, due to material limitations, the ceramic carrier has slow temperature response and relatively high back pressure.

The above discusses both the advantages and disadvantages of using a ceramic carrier in a three-way catalytic converter.
