The working environment of the three-way catalytic converter is very bad, and it is easily affected by various adverse factors, so in order to ensure lower pollutant emissions, but also to make its life longer, the following issues should be paid attention to in daily use.

1, do not use leaded gasoline, leaded gasoline after combustion will emit lead particles, these particles will cover the inside of the three-way catalyst, so that the reaction area of precious metals and exhaust gas becomes smaller, reduce the conversion efficiency and even lead to the failure of the three-way catalyst after lead poisoning.

2, too high temperature will cause chemical changes in the precious metal components in the three-way catalytic converter, reduce the catalytic effect and cause damage, so care needs to be taken to avoid letting the exhaust temperature is too high. In the case of such conditions as missing cylinder, burning oil, oxygen sensor failure, and excessively high water temperature, timely maintenance is required.

3, the three-way catalytic converter is made of honeycomb ceramic material, which is easy to break after collision and external impact, leading to failure and even blocking the exhaust pipe. Therefore, it is necessary to pay attention to check the abnormal sound of the exhaust pipe body, check whether the three-way catalytic converter shell is pothole and damaged during maintenance, and find the problem as soon as possible and deal with it in time.

4, the use of fuel additives need to pay attention to the old car as far as possible not to use products with too strong cleaning capacity, should choose a mild clean type slowly clean up the carbon deposit, to avoid large carbon deposits and other substances into the three-way catalytic converter, resulting in the loss of catalytic ability or it will be blocked.
