Clean Up Your Emissions Game with Volvo D11 D13 D16 DOC
What is it?
The Diesel Oxidation Catalyst (DOC) for the Volvo D11, D13, and D16 engines serves as a frontline emissions-control component. It converts hydrocarbons (HC) and carbon monoxide (CO) in the exhaust into less harmful gases, helping your after-treatment system perform efficiently.
Why choose this DOC?
Designed specifically for the D11, D13, and D16 engine families, this DOC delivers the correct fit and performance you need. A broken or clogged catalyst leads to high back-pressure, frequent regen attempts, or emissions fault codes. With the right DOC, your exhaust system stays clean and effective.
Key Benefits
✅ Breaks down harmful gases for cleaner exhaust output
✅ Safeguards downstream emissions components like DPF and SCR
✅ Helps reduce back-pressure and exhaust flow restriction
✅ Direct-fit design—no guesswork, no mods
✅ Built for heavy-duty operation and high temperature challenges
Applications
Ideal for trucks and equipment powered by Volvo D11, D13, or D16 engines, especially when emissions compliance and engine uptime matter the most.
Installation Notes
Ensure the exhaust system is fully cooled before starting. Inspect the DOC housing, clamps, and seals for wear or soot buildup. Use fresh gaskets and clamps during install. After fitting the new DOC, clear any fault codes and check exhaust system behavior to confirm return to optimal function.
Final Thoughts
If your Volvo engine is showing signs of frequent after-treatment faults, elevated back-pressure, or restricted exhaust flow—this DOC is the go-to replacement. With accurate fit and rugged design, it keeps your system clean, responsive, and road-ready.
