The utility model relates to a post-processor connection pipe structure with resonance holes, which is characterized in that: the connection pipe is a conical pipe with an included angle of 40 degrees, and resonant holes are uniformly distributed on the conical pipe wall; one end is connected with the cylindrical The package carriers are connected in series. Its positive effect is that when the connecting pipe with a resonance hole at an angle of 40 degrees is connected to the intake end of the cylindrical packaging carrier, the exhaust gas from the engine can be evenly distributed to the intake end face of the carrier, ensuring the flow uniformity of the intake air inside the carrier and efficient work of the catalyst. At the same time, the connecting pipe has a resonance hole, which forms a resonance cavity with the post-processor assembly, which can reduce the exhaust noise; b. When the connecting pipe with a resonance hole at an angle of 40 degrees is connected to the outlet end of the cylindrical package carrier, it can reduce the noise of the engine. The regenerative noise generated by the exhaust, meanwhile, the connecting pipe has a resonance hole, which forms a resonance cavity with the after-processor assembly, which can reduce the exhaust noise.
Description
Technical field
The utility model relates to a kind of preprocessor connecting tube structure with the resonance hole, particularly is used for a kind of preprocessor connecting tube structure with the resonance hole of cylindrical preprocessor package carrier assembly, belongs to the auto manufacturing field.
Background technique
At present, domestic commercial car is about to carry out the IV stage Abgasgesetz of GB 17691 or GB 18352.3, and taking the outer exhaust preprocessor cleaning of off-gas of motor machine is its mainstream technology route.
Summary of the invention
The purpose of the utility model is to provide a kind of preprocessor connecting tube structure with the resonance hole, and it had both guaranteed under the inhomogeneity prerequisite of reprocessing carrier flow, can form a resonant cavity that reduces noise with post-processor assembly again.
The utility model technological scheme is achieved in that the preprocessor connecting tube structure in band resonance hole, it is characterized in that: connecting tube is the conical pipe of angle 40 degree, on the taper tube wall, is evenly equipped with the resonance hole; One end and columniform package carrier are connected in series.
The good effect of the utility model is a connecting tube of working as angle 40 degree band resonance holes with after cylindrical encapsulation carrier inlet end is connected; Can make engine exhaust be evenly distributed to carrier air inlet end face, guarantee the flow uniformity of carrier inside air inlet and the efficient operation of catalyzer.Connecting tube has the resonance hole simultaneously, forms a resonant cavity with post-processor assembly, can reduce exhaust sound.
B when the connecting tube in angle 40 degree band resonance holes with after cylindrical encapsulation carrier outlet side is connected, can reduce the regenerated noise that engine exhaust produces, connecting tube has the hole of resonating simultaneously, with resonant cavity of post-processor assembly formation, can reduce exhaust sound.
Description of drawings
Fig. 1 is the preprocessor package carrier assembly connecting tube structural representation in band resonance hole.
Fig. 2 is the structural representation that connecting tube is connected with the outlet side.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further description; As shown in Figure 1, the preprocessor connecting tube structure in band resonance hole is characterized in that: connecting tube 1 is the conical pipe of angle 40 degree, on the taper tube wall, is evenly equipped with resonance hole 2; One end and columniform package carrier 3 are connected in series.
To be with resonance hole 2 connecting tubes, 1 its structure angle during work is that 40 degree are connected with preprocessor package carrier 3; Through having CAE to calculate and verification experimental verification, this connecting tube 1 can make engine exhaust be evenly distributed to carrier air inlet end face with after columniform package carrier 3 inlet ends are connected, and has guaranteed the flow uniformity of carrier inside air inlet and the efficient operation of catalyzer.Connecting tube has resonance hole 2 simultaneously, forms a resonant cavity with post-processor assembly, can reduce exhaust sound.
As shown in Figure 2; When the connecting tube 1 in angle 40 degree band resonance holes 2 with after columniform package carrier 3 outlet sides are connected, can reduce the regenerated noise that engine exhaust produces, while connecting tube 1 has the hole 2 of resonating; Form a resonant cavity with post-processor assembly, can reduce exhaust sound.
