A Proven Controller for Active DPF
Background
-
According to the 'Law for Improvement of Air in the Capital Area, 2003.12' and its Clause 8, the Minister of Environment must set up a plan every decade to reduce and improve air pollution in capital area.
-
The diesel vehicles being out of warranty have to be installed DPF or be scrapped.
-
The act plan of the PHASE 1 had been carried out from 2005 to 2014 and PHASE 2 have been going since 2015.

What's DPF?
-
DPF (Diesel Particulate Filter) is a celluar structured trap filtering PM(Particulate Matter) from diesel exhaust in vehicle and convert PM to the no harmful substance by oxidizing with catalytic reaction.
-
Catalyzed DPF regenerates continuously with the aid of exhaust heat or heating system.

Role of DPF Controller
-
Active Regeneration DPF can regenerate filter even during driving with the aid of catalyst on filter and burner.
-
Burner system heats up exhaust gas and controls inlet temperature of DPF.
-
Safety regarded function are included; extinguish detection, misfiring, over heating of the filter.
-
It uses diesel in a fuel tank and regenerates periodically or when back pressure increases due to soot accumulation.
-
Logging & monitoring device records in the SD card.
