Description

technical field [0001] The invention relates to a biological cleaning solution for carbon deposits in a three-way catalytic converter of an automobile and a use method thereof, belonging to the field of biological environmental protection. Background technique [0002] Three-way catalytic converter poisoning failure and clogging are the most common problems in environmentally friendly engines. Each system of the environmental protection engine works around the center of maximizing the conversion efficiency of the three-way catalytic converter. Once the three-way catalytic converter is poisoned, fails and is blocked, the conversion efficiency cannot be guaranteed, and the environmental protection engine cannot work normally. Therefore, the three-way catalytic converter Maintenance issues are at the center of environmental engine maintenance. [0003] Carbon deposits are a kind of sticky substance produced by unsaturated olefins and gums in fuel at high temperature during the...
