Why You Need a Catalytic Converter
A catalytic converter reduces harmful emissions by converting toxic exhaust gases into less harmful substances. It’s essential for compliance with emission regulations and for maintaining engine performance and fuel efficiency.
How a Catalytic Converter Works
The core components include a ceramic or metallic substrate coated with precious metals—platinum, palladium, and rhodium—that catalyze chemical reactions. Exhaust gases pass through a honeycomb structure, maximizing contact and conversion efficiency. This honeycomb is often referred to as a monolith catalyst support, providing optimal surface area for rapid pollutant breakdown.
Signs You Need a New Catalytic Converter
- Check-engine light stays on
- Reduced engine power and acceleration
- Unusual rattling noises
- Failed emissions test
Maintenance Tips
Regular inspections and proper engine tune-ups prevent premature converter failure. Use high-quality fuel and oil to avoid contamination and clogging. Detailed best practices for DPF maintenance can be found in the EPA DPF guide.
