Lead Cleaner Exhaust Control with PACCAR MX13 DOC
What is it?
The Diesel Oxidation Catalyst (DOC) for the PACCAR MX13 engine is a key part of the after-treatment system. It converts hydrocarbons (HC) and carbon monoxide (CO) in the exhaust into less harmful gases, ensuring your downstream emissions components operate smoothly.
Why choose this DOC?
Built for the MX13 engine, this DOC ensures proper fitment and effective emissions treatment. A degraded or blocked catalyst can cause elevated back-pressure, frequent regenerations, reduced performance, or fault codes. Installing the correct unit helps your exhaust system function reliably.
Key Benefits
✅ Converts HC and CO into cleaner exhaust output
✅ Protects downstream DPF, SCR, and other after-treatment components
✅ Helps reduce exhaust restriction and back-pressure
✅ Direct-fit installation—no modifications required
✅ Designed for heavy-duty use and high-temperature environments
Applications
Ideal for transport and vocational vehicles equipped with the PACCAR MX13 engine, particularly when emissions compliance and system efficiency are critical.
Installation Notes
Ensure the exhaust system has cooled fully before service. Inspect the DOC housing, exhaust piping, clamps and seals for wear or soot buildup. Replace gaskets and clamps to secure a tight installation. After mounting, clear fault codes and monitor system diagnostics to confirm operation and proper exhaust flow.
Final Thoughts
If your MX13 engine is experiencing frequent after-treatment events, elevated exhaust back-pressure, or fault indications, installing the right DOC is essential. With precise fit and robust construction, this part helps maintain cleaner, smoother, and more reliable engine operation.
