How to wash three-way catalytic
Three-way catalyst is an important component in the automotive exhaust gas treatment system and can effectively reduce the emission of harmful gases. However, as the use time increases, the three-way catalyst may degrade due to problems such as carbon deposits and blockage. This article will introduce in detail how to clean the three-way catalyst and provide hot topics and hot content for the past 10 days as reference.
1. The function and cleaning necessity of three-way catalyst
The main function of the three-way catalyst is to convert harmful gases (such as carbon monoxide, hydrocarbons and nitrogen oxides) in the vehicle exhaust into harmless carbon dioxide, nitrogen and water vapor. If the three-way catalyst is blocked or carbon deposits are severe, it will cause the engine power to decrease, fuel consumption will increase, and even trigger the fault light. Therefore, it is very important to regularly clean the three-way catalyst.
2. Steps to clean the three-way catalyst
1.Preparation: Make sure the vehicle is in a cool state and prepare tools such as cleaning agents, gloves, goggles.
2.Disassembly of three-way catalyst: Depending on the model, some exhaust pipes may need to be removed to remove the three-way catalyst.
3.Soak and clean: Put the three-way catalyst into a special cleaning solution and soaks the time according to the degree of contamination, usually from 30 minutes to 2 hours.
4.High pressure water gun flushing: Use a high-pressure water gun to thoroughly flush the interior of the three-way catalyst to ensure that all carbon deposits and impurities are removed.
5.Drying and installation: Dry the three-way catalyst or blow dry with compressed air and reinstall it on the vehicle.
