Muffler Filter Regenerative Control

The muffler filter regenerative control system is designed to effectively burn particulate matter (PM) deposited in the filter using exhaust gases. This is categorized into:

• Own Regeneration: Utilizes high-temperature exhaust gases to activate the catalyst without the diesel oxidation catalyst (DOC).
• Mandatory Regeneration: Involves both auto and manual processes for effective regeneration using DOC and exhaust gases:
  • Auto Regeneration: Auto-initiates within eight hours of the previous regeneration or upon high differential pressure sensor output.
  • Manual Regeneration: Triggered manually via monitor indications and requires specific setup conditions.

Note: Regeneration is more efficient when exhaust temperatures exceed 250u00b0C, with optional fuel injections to enhance the process.
