Volvo D11, D13, D16 DOC
Optimise Exhaust Flow for Volvo D11, D13, D16 Engines
What is it?
The Diesel Oxidation Catalyst (DOC) for Volvo D11, D13 and D16 engines is a critical emissions-control component. It helps convert hydrocarbons (HC) and carbon monoxide (CO) in the exhaust stream into cleaner, less harmful gases, enabling the after-treatment system to operate more reliably and consistently.
Why choose this DOC?
Engineered specifically for the D11, D13 and D16 engine families, this DOC ensures accurate fitment and dependable emissions-system support. A worn or clogged catalyst can lead to increased exhaust restriction, more frequent regeneration events, or fault codes related to emissions control. Installing the correct DOC helps maintain clean exhaust flow and stable system behaviour.
Key Benefits
✅ Converts HC and CO into cleaner exhaust output
✅ Supports downstream after-treatment components and overall system integrity
✅ Helps preserve steady exhaust flow and reduce restriction
✅ Direct-fit design—no modifications required
✅ Built to handle heavy-duty, high-temperature operating environments
Applications
Ideal for heavy-duty trucks and equipment powered by Volvo D11, D13 or D16 engines—especially in applications where emissions compliance and reliable system behaviour are essential.
Installation Notes
Allow the exhaust and after-treatment system to cool completely before servicing. Remove the existing DOC, inspect the housing and adjacent exhaust hardware for soot accumulation, cracks or damage. Install new gaskets, seals and clamps as needed. After installation, clear any emissions fault codes and verify proper exhaust system behaviour via diagnostics.
Final Thoughts
If your D11, D13 or D16-equipped vehicle is showing signs of elevated exhaust restriction, emissions alerts or inconsistent after-treatment system behaviour, replacing the DOC with a correctly matched unit is a practical way to restore clean, dependable exhaust flow. This component plays a pivotal role in maintaining the integrity of the full emissions-control chain and supporting reliable operation.
