Abstract
The utility model relates to a transparent type particle-trapping postprocessor assembly, and belongs to the field of automobile manufacture. Spinning type opening cone-shaped tubes are welded with a casing respectively; the interior of the casing is divided into three cavities, namely a front resonant cavity, a middle resonant cavity and a rear resonant cavity; an end cover is connected with the front end of the casing in a buckling manner; a flange and the end cover are welded with the spinning type opening cone-shaped tubes respectively; a diesel particle oxidation catalyst is welded with a diesel oxidation catalyst; and a tail tube is located at the tail part of the rear spinning type opening cone-shaped tube. The transparent type particle-trapping postprocessor assembly has the advantages as follows: the structure is novel, the assembly is attractive and reliable, the cost is reduced, a welding structure is reduced, the assembly is simple and firm, and the exhaust noise is effectively reduced, so that the exhausted tail gas meets requirements of emission limits at the IV stage and the V stage.
Description
Technical field
The utility model belongs to automobile manufacturing field, particularly a kind of post-processor assembly of diesel engine.
Background technique
At present, the commercial car of domestic coupling diesel engine and passenger vehicle are about to carry out IV, the V stage Abgasgesetz of GB 17691, for the discharging that makes motor car engine reaches lower rules limit value requirement, only depend on that to improve fuel quality and engine working process be to be difficult to realize, need just can achieve the goal by exhaust after treatment system.Present domestic most of automobile does not also have exhaust gas post-treatment device, vehicle exhaust does not reach IV, the emission limit requirement of V stage, along with reality that air ambient faces, country will be strict day by day aspect motor vehicle exhaust emission rules and standard, automobile not only needs to adorn preprocessor, and will be controlled in laws and regulations.
Summary of the invention
The utility model provides a kind of penetrating type granule capturing post-processor assembly, does not also have exhaust gas post-treatment device to solve present most of automobile, and vehicle exhaust does not reach the problem of IV, the emission limit requirement of V stage.
The technical solution of the utility model is: preceding spinning type perforate conical pipe, back spinning type perforate conical pipe welds with shell respectively, enclosure is divided into preceding resonant cavity, middle resonant cavity, three chambeies of back resonant cavity, front cover and shell front end snapping, forward flange, front cover welds with preceding spinning type perforate conical pipe respectively, rear end cover and outer casing back snapping, rear end cover, rear flange welds with back spinning type perforate conical pipe respectively, the diesel oil oxidation catalyst converter is fixedlyed connected with preceding spinning type perforate conical pipe, diesel particulate oxidation catalyzer and the welding of diesel oil oxidation catalyst converter, back spinning type perforate conical pipe and the welding of diesel particulate oxidation catalyzer, tailpipe is positioned at the afterbody of back spinning type perforate conical pipe.
Advantage of the present utility model is: novel structure, and attractive in appearance reliable, reduced cost, reduced welded structure, firmly simple, and effectively reduce exhaust sound, make the tail gas of discharge reach IV, the emission limit requirement of V stage.
Description of drawings
Fig. 1 is that master of the present utility model looks sectional view;
Fig. 2 is the plan view of Fig. 1;
Among the figure: forward flange 1, front cover 2, preceding spinning type perforate conical pipe 3, diesel oil oxidation catalyst converter carrier 4, diesel particulate oxidation catalyzer carrier package assembly 5, shell 6, back spinning type perforate conical pipe 7, rear end cover 8, rear flange 9, tailpipe 10, preceding resonant cavity 601, middle resonant cavity 602, back resonant cavity 603.
Embodiment
Preceding spinning type perforate conical pipe 3, back spinning type perforate conical pipe 7 welds with shell 6 respectively, shell 6 inside are divided into preceding resonant cavity 601, middle resonant cavity 602,603 3 chambeies of back resonant cavity, front cover 2 and shell 6 front end snappings, forward flange 1, front cover 2 welds with preceding spinning type perforate conical pipe 3 respectively, rear end cover 8 and shell 6 rear end snappings, rear end cover 8, rear flange 9 welds with back spinning type perforate conical pipe 7 respectively, diesel oil oxidation catalyst converter 4 is fixedlyed connected with preceding spinning type perforate conical pipe 3, diesel particulate oxidation catalyzer 5 and 4 welding of diesel oil oxidation catalyst converter, back spinning type perforate conical pipe 7 is positioned at the afterbody of back spinning type perforate conical pipe 7 with diesel particulate oxidation catalyzer 5 welding, tailpipe 10.
Preceding spinning type perforate conical pipe makes engine exhaust be evenly distributed to the diesel oil oxidation catalyst converter, make air-flow be distributed to diesel oil oxidation catalyst converter end face uniformly, diesel particulate oxidation catalyzer back segment has welded back spinning type perforate conical pipe, diesel oil oxidation catalyst converter, the welding of diesel particulate oxidation catalyzer are together in series, make that the assembly internal structure is simple, sound construction, sound attenuation hole on preceding spinning type perforate conical pipe and the back spinning type perforate conical pipe has reduced exhaust sound.3 noise elimination resonant cavities of assembly inside make assembly possess good noise reduction.
