[VonDaniela]

The automotive three-way catalytic converter needs cleaning when symptoms such as difficulty starting, weak acceleration, inability to reach higher speeds, white smoke from the intake manifold, or even backfiring occur. Additional information on the three-way catalytic converter: 1. Reasons for cleaning the three-way catalytic converter: Under normal circumstances, the minimum service life of a three-way catalytic converter is approximately 130,000 km. With proper use, it generally does not fail. The common issues encountered are blockages, excessive carbon deposits, poor oil quality, severe oil burning, and prolonged driving in congested roads, all of which can cause the three-way catalytic converter to clog. In such cases, cleaning the three-way catalytic converter is usually sufficient. 2. Timing for cleaning the three-way catalytic converter: It can be based on the maintenance manual or the actual condition of each vehicle. The specific judgment is that once the three-way catalytic converter is clogged, the engine's performance will severely deteriorate, necessitating cleaning. If the vehicle has exceeded 30,000 km without exhibiting the above issues, cleaning may not be necessary.
