Can DPF cause white smoke?
In a Diesel engine with a Diesel particulate filter (DPF) system, high-sulfur fuel causes white smoke containing odorous and harmful pollutants during DPF regeneration. … The white smoke was observed when the catalyst temperature was more than 450°C, under conditions such as the early stage of DPF regeneration.
Is idling bad for DPF?
The DPF requires periodic soot removal cycles, termed “regeneration” or “regen” for short. These regens burn the accumulated soot out of the DPF at extremely high temperatures. … While the filter burns off soot at speed, soot will accumulate during idling or slow traffic.
