1. Environmental performance: When cars with three-way catalytic converters emit exhaust gas, the emissions of harmful substances will be greatly reduced, causing less environmental pollution.Cars without three-way catalytic converters have higher emissions of harmful substances in the exhaust and cause greater environmental pollution.

2. Fuel economy: The three-way catalytic converter can effectively improve the combustion efficiency of fuel, thereby improving the fuel economy of the car.Cars without three-way catalytic converters have lower fuel combustion efficiency and poor fuel economy.

3. Power performance: The three-way catalytic converter can improve the power performance of the engine and make the car accelerate faster.For cars without a three-way catalytic converter, the engine's power performance may be affected to a certain extent.

4. Service life: The three-way catalytic converter has a long service life, generally up to 8-10 years.For cars without a three-way catalytic converter, the service life of the engine may be affected.

5. Maintenance cost: The maintenance cost of the three-way catalytic converter is relatively high. Once damaged, the three-way catalytic converter needs to be replaced with a new one.Cars without three-way catalytic converters have relatively low maintenance costs.The three-way catalytic converter is an important part of the automobile exhaust system.

It is mainly responsible for processing and reducing the exhaust gas emitted by the engine, especially converting CO, HC and NOx in the exhaust gas into harmless substances, thereby reducing the environmental impact of automobile exhaust gas. pollute.
