Exhaust Three-Way Catalyst Used In 3 Way Catalytic Converter Universal Euro

Gasoline Ceramic Metal Euro 4/5/6 Auto Exhaust System TWC Three-Way Catalyst

TWC Three Way Catalyst

Three-way catalysts (TWC) are designed to simultaneously convert three
pollutants to harmless emissions:

Carbon Monoxide (CO) → Carbon Dioxide (CO2)
Hydrocarbons (HC) → Water (H2O)
Oxides of Nitrogen (NOx) → Nitrogen (N2)
A three-way catalyst can cut CO, HC and NOx by over 99% if the air to fuel
ratio is accurately controlled. Three-way catalysts will only give full
conversion of each of these three pollutants in a gas stream containing a
stoichiometric ratio of CO and NOx.

Product introduction:

TWCs can efficiently convert harmful hydrocarbons (HC), carbon monoxide (CO)
and nitrogen oxides (NOx) in the exhaust gas of gasoline vehicles into harmless
water (H2O), carbon dioxide (CO2) and nitrogen (N2) through oxidation-reduction
