Purpose, Function
Purifies contaminants in the exhaust gas by utilizing the chemical reactions of the three-way catalytic converter.
A WU-TWC and a TWC have been adopted.
The three-way catalyst is integrated with the exhaust manifold.
Because the catalyst receives the high temperature exhaust gas just after the gas is exhausted, it activates quickly and achieves an improved purification performance.
A single-nano catalyst has been adopted in which the purification performance can be maintained using less precious metal materials than conventional catalysts.

A single-nano catalyst has been adopted for the under-floor three-way catalyst. With a conventional three-way catalyst, the precious metals move and agglutinate to each other by the heat of the exhaust gas because they are structured such that they adhere on catalyst material. Therefore, it was necessary to use a large amount of precious metal because it is estimated that the purification performance lowers due to the decrease in the surface area of the precious metals. The single-nano catalyst is structured such that it embeds small precious metal particles into the catalyst material. Because the precious metal particles do not agglutinate on the surface of the three-way catalyst, it can maintain superior purification performance using less precious metal than the conventional system.

Operation
Contaminants in the exhaust gas (HC, CO, NOx) are purified by oxidization and deoxidization while they are passing through the catalytic converter.
Oxidization process
Noxious hydrocarbon (HC) and carbon monoxide (CO) are bound with oxygen and converted to non-noxious carbon dioxide and water.
O2+HC+CO>CO2+H2O
Deoxidization process
Noxious nitrogen oxide (NOx) is converted to non-noxious nitrogen and oxygen. A part of the oxygen generated in this process is used in the oxidization process.
NOx>N2+O2
