Background technique
DPF is limited the ability to bear of soot, when the soot of DPF building up inside is more than its maximum load-carrying capacity
When, DPF internal circulation air-flow can be made to be hindered, so that pressure drop increases, DPF is caused to block.Therefore, DPF system must
Reliable Strategy for Regeneration Control must be matched will not be blocked with ensuring DPF in use.Most of DPF is used passively again
The control strategy that raw mode, absolutely a small number of DPF are aided with initiative regeneration using passive regeneration.DPF passive regeneration refer to only according to
Make the technology of dpf regeneration by engine exhaust heat.When air-flow passes through DPF, the soot in tail gas can be trapped in filtering and be situated between
In matter, these are captured and the carbon soot particles stored occur continuously with the NO2 generated by prime DOC at a proper temperature
Property passive regeneration reaction generate harmless CO2 (NO2+C → CO2+NO), to have the function that eliminate particulate matter.DPF active is again
It is raw to refer to that control system by numerical value such as revolving speed, charge flow rate, fuel flow, the exhaust back pressures of reading engine, passes through calibration
Whether good exhaust back pressure MAP chart is more than its bearing capacity come the soot for determining DPF trapping, when close to its bearing capacity, is
System can automatically control external accessory work, delivery temperature be increased to 550 DEG C or so, so that the soot being collected into is quick
Dispose.
Active regeneration system currently on the market mainly increases a set of fuel injection system, and the fuel oil of injection is before DPF
Combustion chambers burn, so that the delivery temperature in equipment is increased to >=550 DEG C, the carbon particle of DPF trapping at this temperature with tail gas
In O2 occur chemical reaction generate CO2, with this come remove DPF collection carbon particle.This method can greatly improve DPF's
Regeneration efficiency, but this control strategy and its complexity, manufacturing cost are also relatively higher.
