Does every car have a three-way catalytic converter?

At present, every family car is basically equipped with a three-way catalytic converter, because the three-way catalytic converter has the function of purifying exhaust gas, and the exhaust emission of the car equipped with the three-way catalytic converter will not exceed the standard.

When the high-temperature automobile exhaust gas passes through the purification device, the purifying agent in the three-way catalyst will enhance the activity of CO, HC and nitrogen oxides, prompting them to carry out certain redox chemical reactions, in which CO is oxidized into colorless and nontoxic carbon dioxide gas at high temperature; HC compounds are oxidized to water and carbon dioxide at high temperature; Nitrogen oxides are reduced to nitrogen and oxygen. Three kinds of harmful gases are changed into harmless gases, thus purifying automobile exhaust.

When the three-way catalytic converter is blocked and needs high-pressure exhaust, the blockage will lead to poor exhaust and affect the air intake, which will further lead to the decline of engine power, leading to the decline of power and the inability to refuel. In order to get the same power output, the driver needs to step on the accelerator, which leads to an increase in fuel consumption. Usually, the three-way catalytic converter needs to be cleaned every 30,000 kilometers, and the three-way catalytic converter needs to be cleaned every time the nozzle, throttle and air inlet are cleaned.
