Abstract
A method for improving automobile exhaust is disclosed. A catalytic converter is cooled down. The outer surface of the catalytic converter is covered with an infrared thermal radiation material, or black anodizing is carried out on the outer surface. Therefore, the surface thermal radiation of the catalytic converter is improved, and the catalytic converter can be kept being operated under a normal working temperature.
