Carbon Make Catalyst Blockage?
First, the Three-Way Catalytic Converter is on the exhaust duct between the exhaust manifold and the muffler, using platinum, rhodium, These precious metal catalysts of palladium convert harmful substances (CO, NOX, HC) in the exhaust gas into harmless substances.
◆ CO+1/2O2→CO2
◆ H4C2+3O2→2CO2+2H2O
◆ NOX+CO→N2+CO2
The cause of catalytic failure may be that the exhaust temperature is too high. (>1000 °C, the catalyst will be out of action).
In addition, some impurities and carbon deposits will adhere to the surface during the driving process. In addition to the fact that the catalyst cannot be effectively contacted with CO and HC, the ternary catalyst is blocked by carbon deposit, which also causes the vehicle power come down. Let’s regularly clean carbon, maintain a good power output and protect the earth at the same time.
