When Did the Three-Way Catalytic Converter Start Being Used?

[EzraFitz]

The three-way catalytic converter began production and use in 1990. It is a crucial and essential component in automotive exhaust treatment. Specific details are as follows: The three-way catalytic converter is the most important external purification device installed in a vehicle's exhaust system. It converts harmful gases such as carbon monoxide emitted from the vehicle's exhaust into harmless carbon dioxide, water, and nitrogen through oxidation and reduction reactions. The three-way catalytic converter is installed in the engine's exhaust pipe, where it facilitates these reactions to release carbon dioxide and nitrogen. The three-way catalytic converter directly impacts whether a vehicle's exhaust emissions meet regulatory standards. Damage to the three-way catalytic converter does not affect the normal operation of the vehicle but can lead to increased fuel consumption, incomplete combustion, and carbon buildup in the cylinders and spark plugs. Therefore, it is necessary to replace or clean the three-way catalytic converter on schedule. Maintenance of the three-way catalytic converter should typically be performed at authorized 4S shops or reputable repair facilities, and the maintenance cycle should not be excessively prolonged.
