Requirements for Regeneration

Vehicle Duty Cycle

Passive DPF's center body is coated with a proprietary soot ignition catalyst. The soot ignition catalyst typically displays a balance point of 260C to 325C. At the balance point, the rate of soot accumulation equals the rate of soot combustion. For vehicle duty cycles in which exhaust temperatures exceed the balance point for at least 25% of the time, the catalyst will maintain the DPF through passive regeneration. When these duty cycle conditions are met, the only maintenance required is periodic removal of accumulated ash left after the combustion of the diesel particulate / soot.

If a vehicle duty cycle is in question, data logging will be performed to ensure the DPF will passively regenerate with the current vehicle operation. (EGS will determine if data logging is necessary). To log data, a thermocouple is fit within the exhaust stream, where the DPF will be installed if qualified, and connected to a small data storage device. The vehicle is then operated over its normal duty cycle. Typical data logging is 3-5 days in order to capture all possible operating conditions. After the data is recorded, the thermocouple is removed and the downloaded data sent to the EGS Technical Center (info@EglobalSolutions.net) for analysis.

Fuel

All DPF's should only be used with engines operating diesel fuel meeting European or American specifications for road use with less than 50ppm sulfur content. Fuel containing higher levels of sulfur will have negative consequences on maintenance intervals, unit durability, and emission reduction efficiency. As a result of these negative effects the conditional warranty may be affected.
