Will a car without a catalytic converter be inspected on the road?

[CaliDella]

Vehicles without a catalytic converter will be inspected on the road, and it is necessary to install one promptly. Below is detailed information about automotive catalytic converters: 1. Overview: The catalytic converter, installed in the vehicle's exhaust system, is the most crucial external purification device. It transforms harmful gases such as CO, HC, and NOx emitted from the vehicle exhaust into harmless carbon dioxide, water, and nitrogen through oxidation and reduction reactions. 2. Additional Information: When high-temperature vehicle exhaust passes through the purification device, the purifying agents in the catalytic converter enhance the activity of CO, HC, and NOx gases, promoting their oxidation-reduction chemical reactions. Because this converter can simultaneously convert the three main harmful substances in exhaust gases into harmless substances, it is called a three-way catalytic converter.
