SINOTRUK HOWO TRUCK DPF Active Regeneration/Inhibit Regeneration Control Switch 812W25503-7034
Product Features
1. DPF Active Regeneration (Manual Stationary Regeneration): When the DPF (Diesel Particulate Filter) indicator light on the dashboard flashes or a "Perform Stationary Regeneration" prompt appears, place the truck engine in neutral and let it idle. Press and hold the "Active Regeneration" side of the switch for 3–5 seconds; upon detecting the signal, the system will actively raise the exhaust temperature to burn off accumulated soot. The entire process takes approximately 20–30 minutes.
2. DPF Regeneration Inhibit (Regeneration Suppression): When the truck is entering areas such as gas stations, chemical plants, warehouses storing flammable or explosive materials, grain depots, or enclosed underground garages, the driver must press the "Regeneration Inhibit" side of the switch if the system has triggered automatic regeneration. Key function: This forces the after-treatment system to stop fuel injection for heating, preventing the exhaust pipe from emitting extremely high-temperature gases that could ignite the surrounding environment; this is a critical fire safety protection feature.
