What are the consequences of removing the catalytic converter?

[VanVivian]

The catalytic converter in a car is designed to enhance the purification of vehicle exhaust. If removed, it can have the following effects: 1. Increased vehicle emissions: Without the catalytic converter, the exhaust gases cannot be effectively purified, leading to emissions that exceed standards. 2. Reduced power and increased fuel consumption: Removing the catalytic converter may cause blockages, resulting in decreased engine power and higher fuel consumption. Below is an introduction to the catalytic converter: 1. Function: The catalytic converter, installed in the vehicle's exhaust system, is the most important external purification device. It converts harmful gases such as CO, HC, and NOx from vehicle exhaust into harmless carbon dioxide, water, and nitrogen through oxidation and reduction. 2. Hazards of malfunction: If the mixture is too lean, it can cause ignition difficulties, weak driving, engine backfire, etc. If the mixture is too rich, it can increase fuel consumption, incomplete combustion, and severe carbon buildup in the cylinders and spark plugs. In such cases, the engine warning light should illuminate.
