DPF Regeneration System Function:
A metered amount of HC (diesel fuel) is injected into the exhaust gas stream of a diesel engine before the DOC promoting exothermic process that increase the exhaust gas temperature before the DPF. The higher exhaust gas temperature initiates the burning of the soot in the DPF. The soot burning will continue until the full DPF regeneration achieved.
DPF Regeneration System Features:
- Reduce PM by >85%.
- Reduce CO and THC by >85%.
- Limit NO Formation.
- Minimum Precious Metal (washcoat) usage for DPF.
- Potential NOx Reduction by 20 to 25%.
- Sustain high exothermic frequency.
- OEM level exhaust noise attenuation.
DPF Regeneration Operation:
The exhaust back pressure (monitored at all time), DPF temperature and soot loading time after each re-generation are the triggering mechanisms for the start / stop of the diesel fuel injection into the exhaust system. The Electronic Controlling Unit, SEECDPF, controls the regeneration process, safety, and the durability of the DPF. User can set up the provided calibration parameters to a desired level to achieve a customized regeneration process and the frequency of the regeneration. The calibration can be optimized to minimize the fuel economy impact during the back pressure build up and the regeneration. The closed loop temperature control strategy safeguards the DPF and maintain its operation within the safe thermal gradients.
ServoTech offers three distinct technologies for PM control and DPF Regeneration Process for various applications and requirements and (CARP EBA) Standards and Regulations.
ServoTech offers three distinct technologies for PM control and DPF Regeneration Process for various applications and requirements and (CARP EBA) Standards and Regulations:
1. HC Injection: to raise Exhaust Temperature via Exothermic Process on the Diesel Oxidation Catalyst (DOC) to burn off the Soot and Regenerate the DPF.
2. Electrically Heated.
3. Fuel-Borne Catalyst.
