PERFORMANCE, QUALITY, AND COMPETITIVE PRICING
Diesel Oxidation Catalyst
- "Catalytic Converter" of the diesel engine.
- Superheats toxic exhaust gases, turning the gases into safe carbon dioxide and water.
- Prepares exhaust gases for the DPF.
- Does not require cleaning/maintenance.
- PowerEdge DOC's are made with fully coated OEM grade substrates for high-efficiency heat transfer. Substrates are placed in stainless steel cannisters for corrosion protection. All part numbers come with clamps and gaskets.
Diesel Particulate Filter
After exhaust gas passes through the DOC, the DPF is used to capture remaining diesel particulate matter.
Regeneration:
DPFs work like a self-cleaning oven. They are always heating up to burn off the captured particulate matter (soot) and keep the substrate clear. There are three types of regeneration:
Passive: passive regeneration is always happening. The DPF is maintaining a temperature based on the temperature of the exhaust to manage its normal soot load (up to 300 Celsius).
Active: active regeneration requires the seventh inject to dose the exhaust with diesel fuel prior to entering the DOC. This will super heat the exhaust for the DPF and burn off more soot. Active regeneration requires fuel and impacts fuel economy. The temperature ranges from 300 Celsius to 600 Celsius going into the DPF.
Forced: forced regeneration requires the vehicle to be parked while the DPF heats for 30 minutes - 2 hours. Parking the Vehicle allows the DPF to become heat-soaked at temperatures of 550-600 Celsius.
