Product Readme
Our company has successfully developed many types of three-way Catalytic Converter, which are
suitable for cars in all types and meet the emission standard. As customers requests, all kind of
three-way Catalytic Converter can be explored and produced.
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 exerts its function, this A/F can be realized.
Subst ra te :
The basic material is ceramic(MgO2, AL2O3SiO2). The aim is to offer inert physical structure for
carrying catalyst coating. In order to make a biggiBHLJ catalytic coating in a lesser volume, we
make the surface of the substrate alveolate.
Coat ing :
There is a loose layer in the surface of substrate which is mainly made of metal oxides-AL2O3. As
a very rough surface, the actual wall area has increased about 7000 times, which greatly increase
the activated surface and the capacity of oxygen storage of the car/ motorcycle three-way catalyst.
Assistant catalyst which contains Zr, Ce and other elements and the main catalyst which contains
Rh, Pd, Pt and other precious metals are coated in the external activated surface.

Pur i f i can t
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 NOx, the activity of the gas is enhanced under high temperature.
As a result, the CO would be oxidized into CO2, the HC is turned into H2O and CO2 , and the NOx
is deoxidized into nitrogen.

Opera t ing p r inc ip le
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 gases would be turned into the non-harmful gas to purify the exhaust.
Good char ac te r is t i cs
Using honeycomb ceramics carrier that has many advantages, such as low cost, strong adhesive
and active ingredient, long life etc.; adopting late-model of rare earths (material Zirconium and
Titanium) to advance the heat resistance and activity of catalyst; introducing transitional metal,
alkaline earth metal and active material of little precious metal that has plenty of excellences, such
as high purification rate, and low burning temperature etc.; making use of new-style of oxygen
storing stuff that reduces the burning temperature of catalyst and complete transformation.
The catalytic converter applied and produced by this technique has past the test of BHLJanghai
national exhaust gas test center and Tianjin university burning internal-combustion engine lab, the
result indicates: using this cat that can make the emission standard reach European no.3 and meet
the technique requirements the converter product demands. The special exhaust gas catalytic
converter for CNG engine is composed of two parts, that are catalyst of honeycomb ceramics and
metal BHLJell, the main elements is: The exhaust gas pass through the catalyst of honeycomb
ceramics, the active ingredient of catalyst (mostly are metal oxide of rare earths, precious metal
and transitional metal) is able to carry out the catalysed reaction fully under the temperature
condition of 200 to 300 above converting the harmful element such as CO, HC, NOX etc. to
innocuous water, carbon dioxide and nitrogen. A key technique is the core of this program is the
exhaust gas decontamination technique of CNG engine, which belongs to three-way
decontamination catalyst technique, and is the main means of dealing with exhaust gas of CNG.

The main pollution exhaust from car: HC, Nox, CO, PM. They are mainly let off through exhaust
pipe, in which, there are nearly 45% HC and little other pollution substance emitted by crankcase
and fuel system.
In the above pollution exhaust, CO, the half burned production of fuel, is worse for health. HC,
constituted by 200 types of elements, is the production, mostly made by half burned and fuel
vaporized action, which contain cancerous substance. Nox, composed by chemical combination of
N2 and O2 under high temperature and pressure condition in firebox, becomes NO2 in the air, which
with strong poisonousness is terrible for human being and plant, and one of main substance that
form acid rain and actinic fog. PM ,its main ingredient is carbonic smoke ,which with a great deal of
chemical substance comprises cancerous substance ,will stay long in the lung of human after
having absorbed.
As the quantity of car increasing, the harm and danger of pollution exhaust of car brought to the
environment will be heavy increasingly, thereby, every nation and area around the world
establiBHLJ the emission limit value of car exhaust one after another, thereinto, the European
standard , EU constituted, is the reference for most of countries and areas.
Not ices
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 , it BHLJould not exceed 1000.
Otherwise it would accelerate the aging and BHLJorten the life-span of the Catalyzer.
4. If the piston is damaged, the oil would flee into the engine, which would reduce the activity ofthe Catalyzer.

2.2 Diese l soot par t icu la te f i l te r
P r o d u c t Re a d me
The product is one kind of wall flowed honeycomb ceramic filter with special structure and material.
It is applied in the tail gas clean-up plant of diesel. It utilizes the pore of wall flowed filter to cut-off
and catch the soot particulate in the tail gas of diesel and then purifies the tail gas. It is made by
two materials: cordierite and carborundum.
