What are the consequences of removing the catalytic converter?

[McVanessa]

Removing the catalytic converter mainly has the following consequences: 1. Increased vehicle exhaust emissions: After removing the catalytic converter, the vehicle's exhaust cannot be effectively purified, leading to excessive emissions. 2. Reduced vehicle power and increased fuel consumption. 3. Failure to meet vehicle exhaust emission standards, resulting in the vehicle failing the annual inspection. Here is some additional information: 1. Installation location and function: The catalytic converter is the most important external purification device installed in the vehicle's exhaust system. It converts harmful gases such as carbon monoxide (CO), hydrocarbons (HC), and nitrogen oxides (NOx) in the vehicle's exhaust into harmless carbon dioxide, water, and nitrogen through oxidation and reduction. 2. Origin of the name: Since this converter can simultaneously convert the three main harmful substances in the exhaust into harmless substances, it is called a three-way catalytic converter.
