Product Overview
Description
Product Introduction
1.Catalytic converter is a device used to reduce the toxicity of emissions from an internal combustion engine.
2.By cleaning up the pollutants left over from combustion through chemical Oxidation and Reduction reactions, the catalytic converters convert the tailpipe emissions of hydrocarbons (HC) and carbon monoxide (CO) into nitrogen (N2), carbon dioxide (CO2) and water (H2O), and elevate the harmful emissions to extremely low levels.

Ceramic Catalytic Converter:
The honeycomb ceramic substrate used in cars, and work as catalytic converter core of Car Emission Systeme. We can be ustomized as per clients' requirements.
The characteristic of honeycomb ceramic catalyst substrate used in cars as follows:
1).High specific surface area: ensure exhaust gas could contact weigh catalyst enough.
2).Stable water absorption: guarantee catalyst could be firmly and evenly coated on the surface of substrate, so it's no waste for too thick coating.
3).Fast in temperature rising: after starting up engine, the temperature of substrate could reach the active temperature of catalyst in the shortest time.
4).Low exhaust resistance: ask exhaust resistance of substrate to engine low, so that it won’t affect the performance of engine.
5).high intensity: substrates work in bumpy cars, so the intensity of substrates must be too high to be destroyed
6).perfect assembly: substrates are parts of exhaust; perfect appearance and exact.
Material: cordierite ,silicon carbide
