Abstract
The present invention relates to a kind of straight-through particle filtration post-processor assembly, encapsulated assembly, hush tube, taper delivery line and tailpipe formed by flange, end cap, taper ingress pipe, dividing plate, DOC encapsulation assembly, shell, straight-through particle filtration post-processor; It is characterized in that: straight-through particle filtration post-processor encapsulation assembly is in the inside of shell, utilize two dividing plates and connecting tube to support; Taper ingress pipe encapsulates assembly weld with end cap, DOC respectively; Taper delivery line encapsulates assembly weld with end cap, straight-through particle filtration post-processor respectively.Which ensure that making full use of of catalyzer, thus realize PM transformation efficiency >=60% under each operating mode of motor, assembly possesses good noise reduction simultaneously; Have the function simultaneously reducing PM, CO, TCH and noise in diesel engine exhaust, assembly can meet the noise emitted by accelerating motor vehicle regulation of GB 1495 and the IVth stage emission regulation of GB 17691 simultaneously.
Description
Technical field
The present invention relates to a kind of straight-through particle filtration post-processor assembly, a kind of straight-through particle filtration post-processor assembly of particularly light commercial vehicle and middle bus assembling.
Background technique
At present, domestic light commercial vehicle and middle bus are about to the IVth stage emission regulation performing GB 17691, and straight-through particle filtration reprocessing is wherein a kind of technology path.
Summary of the invention
The object of the present invention is to provide a kind of straight-through particle filtration post-processor assembly, according to motor raw emissions situation, appropriate design preprocessor and noise elimination structure, the scientific management flowing of engine exhaust in assembly inside, engine exhaust is made to be evenly distributed to DOC carrier and the straight-through particle filtration post-processor end face of series winding, ensure that making full use of of catalyzer, thus PM transformation efficiency >=60% is realized under each operating mode of motor, assembly indoor design simultaneously has 4 noise elimination cavities, respectively: resonant cavity, expansion cavity, expansion cavity, resonant cavity, therefore assembly possesses good noise reduction, taper delivery line reduces back pressure.
Technological scheme of the present invention is achieved in that a kind of straight-through particle filtration post-processor assembly, is encapsulated assembly, hush tube, taper delivery line and tailpipe formed by flange, end cap, taper ingress pipe, dividing plate, DOC encapsulation assembly, shell, straight-through particle filtration post-processor; It is characterized in that: straight-through particle filtration post-processor encapsulation assembly is in the inside of shell, utilize two dividing plates and connecting tube to support; Taper ingress pipe encapsulates assembly weld with end cap, DOC respectively; Taper delivery line encapsulates assembly weld with end cap, straight-through particle filtration post-processor respectively.
Described taper ingress pipe has resonance holes and is communicated with resonant cavity I, the gap that DOC encapsulates assembly rear end and first straight-through particle filtration post-processor front end forms expansion cavity II, the gap that first straight-through particle filtration post-processor rear end encapsulation assembly and second straight-through particle filtration post-processor encapsulate assembly front end forms expansion cavity III, and taper delivery line has resonance holes and is communicated with resonant cavity IV.
Good effect of the present invention ensure that making full use of of catalyzer, thus realize PM transformation efficiency >=60% under each operating mode of motor, and assembly possesses good noise reduction simultaneously, and taper delivery line reduces back pressure; It is the integrated assembly of straight-through particle filtration post-processor and noise elimination structure, have the function simultaneously reducing PM, CO, TCH and noise in diesel engine exhaust, assembly can meet the noise emitted by accelerating motor vehicle regulation of GB 1495 and the IVth stage emission regulation of GB 17691 simultaneously.
Accompanying drawing explanation
Fig. 1 is straight-through particle filtration post-processor assembly internal structure schematic diagram.
Fig. 2 is the auspicious figure of straight-through particle filtration post-processor assembly internal structure.
Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described: as shown in the figure, straight-through particle filtration post-processor assembly, is encapsulated assembly 7, hush tube 8, taper delivery line 9 and tailpipe 10 formed by flange 1, end cap 2, taper ingress pipe 3, dividing plate 4, DOC encapsulation assembly 5, shell 6, straight-through particle filtration post-processor.Straight-through particle filtration post-processor encapsulation assembly 7 is in the inside of shell 6, utilizes two dividing plates 4 and connecting tube to support; Taper ingress pipe 3 encapsulates assembly 5 weld with end cap 2, DOC respectively; Taper delivery line 9 encapsulates assembly 7 weld with end cap 2, straight-through particle filtration post-processor respectively.
Described taper ingress pipe 3 has resonance holes and is communicated with resonant cavity I, DOC encapsulates the gap that assembly 5 rear end and first straight-through particle filtration post-processor encapsulate assembly 7 front end and forms expansion cavity II, the gap that first straight-through particle filtration post-processor encapsulation assembly 7 rear end and second straight-through particle filtration post-processor encapsulate assembly 7 front end forms expansion cavity III, and taper delivery line 9 has resonance holes and is communicated with resonant cavity IV.
Front and rear cover and shell snap fastener are formed straight-through particle filtration post-processor assembly.
When engine operation, first engine exhaust by taper ingress pipe 3, makes engine exhaust evenly arrive DOC carrier end face, and DOC reduces carbon monoxide (CO), total hydrocarbons (THC) in exhaust, produces nitrogen dioxide (NO simultaneously
2); Then straight-through particle filtration post-processor catches the particulate matter (PM) in tail gas, utilizes the NO that DOC produces
2carry out low-temperature burning with PM, by passive regeneration and the Fine calibration of system, make exhaust contaminant satisfy regulatory limit value.
