Three-Way Catalytic Converter:
Features:
1) Structure: three-way catalytic converter resembles muffler. Its
outside in the shape of canister is made of stain steel plate.
Between the double sheet of interlayer, there is the heat-resistant
material (asbestos fibre felt). And inside in the center of reticulate
clapboard, the purificant is equipped
2) Purificant: the purificant is composed of carrier and catalyzer. The
carrier is made of AI2O3 in the shapes of sphericity, multi-prism,
reticulate clapboard etc. Purificant, in fact has the function of
catalysing, so it is also called catalyzer. Platinum, rhodium and
palladium can be used as catalyzer, and use one of them sprayed and
covered onto the carrier, then the purificant forms
3) Working theory: 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
4) Notice:
a) Let the engine maintain the good working status-the ideal A/F
and safe combustion
b) Avoid suddenly jump-starting the car using the largest accelerograph
c) The best working temperature of catalyzer is 400-800o C, it should
not exceed 1000o C, otherwise it would accelerate the aging and
shorten the life-span of the catalyzer
d) If the piston is damaged, the oil would flee into the engine, that
would reduce the activity of the catalyzer
The main chemical reaction formula as follows:
Oxidation reaction: HC+O2=H2O+CO2
Deoxidization reaction: NOx+HC+CO=N2+H2O+CO2=
