Automobile Honeycomb Ceramic Catalyst Catalytic Converter

Catalytic converters are amazingly simple devices, so it is incredible to see how big an impact they have. A catalytic converter is a device causes conversion of harmful gases into mostly harmless products. Catalytic converters were first widely introduced in American production cars in 1975. Diesel particulate filter (DPF) substrate is a device designed for diesel engine exhaust gas purification, to remove diesel particulate matter or soot from the exhaust gas of a diesel engine.
 
The three-way Catalytic Converter can eliminate 90% amount of the three main pollutants (hydrocarbon, carbon monoxide and nitrogen oxide). A complete catalyzing reaction depends on the preserving degree of the mixed fuel on the small side of A/F (rate of air and fuel). And only the normal system of oxide sensor exert its function, this A/F can be realized.
 
When the exhaust is passing through the exhaust pipe, CO , HC , and Nox ---the three types of gas are passing through the clarifier of the reactor in the three-way Catalytic Converter , the activity of the gas would be enhanced, they would be under an oxidation and deoxidization reaction. Under such a high temperature, the CO would be oxidated into a gas without color and poison--CO2; the HC compound would be turned into H2O and CO2; and the Nox would be deoxidated into Nitrogen. The three nocuous gas would be turned into the non-harmful gas to purify the exhaust.

Purificant
Our catalyst is coated with noble metals of Pt, Pd and Rh. When the exhaust is passing through the three-way catalyst, CO, HC and NO x , the activity of the gas is enhanced under high temperature. As a result, the CO would be oxidized into CO 2 , the HC is turned into H 2 O and CO 2 , and the NO x is deoxidized into nitrogen.

Notices 
1).Let the engine maintain the good working status------the ideal A/F and safe combustion.
2).Avoid suddenly jump-starting the car using the largest accelerograph.
3).The best working temperature of Catalyzer is 400 -800 °C , it should not exceed 1000 °C ; otherwhise it would accelerate the aging and shorten the life-span of the Catalyzer .
4).If the piston is damaged, the oil would flee into the engine, that would reduce the activity of the Catalyzer.
