Description

Quick-insertion type silencer for automobile turbocharging

Technical Field

The utility model relates to a car connecting pipe, in particular to connecting pipe for automobile worm wheel pressure boost.

Background

With the increasing environmental pressure, nowadays, various countries have high energy conservation and emission reduction flags, and the development of the turbocharging technology will enter a new stage: small displacement turbocharging will become the development trend of the future automobile market.

The turbocharging system recovers, burns and recycles tail gas exhausted by the engine, reduces the pollution of the tail gas of the engine to the environment and the atmosphere, and can recycle a fuel oil system, so that the engine pursues a high rising rate. At present, the turbocharged engine becomes a domestic research and development direction and development trend, and the prospect is very optimistic. The worm supercharging system comprises a turbocharger, medium cold air, an air inlet bypass valve, an exhaust bypass valve and a matched air inlet and exhaust pipeline. Wherein the turbocharger is an air pump that operates using the remaining energy in the engine exhaust; the turbocharger connecting pipe is used for discharging the exhaust gas of the turbocharger, so that the discharged exhaust gas is combusted secondarily, the combustion efficiency of fuel oil is improved, and the exhaust emission is reduced. The inner wall hole of the silencer in the prior art is usually designed in a rectangular shape, and the silencer has the following defects:

1. the area of the rectangular hole is generally larger than that of the round hole, and the design hole position arrangement is not as flexible as that of the round hole;

2. the processing size of the rectangular structural die is not easy to guarantee, the sizes of all holes are not uniform, the size consistency is poor, the air flow is unbalanced in and out at the same position, the pressure loss curve drift is easy to generate, and therefore the noise reduction effect is reduced;

3. rectangular hole mould is difficult for processing, and the mould maintenance is difficult, and the mould maintenance cost is high.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing an automobile turbocharging is with inserting formula muffler soon improves the efficiency of ventilating, strengthens its amortization performance.

The purpose of the utility model is realized like this: the utility model provides an automobile turbocharging is with formula muffler of inserting soon, establishes the connecting pipe in hush pipe periphery including the cover, the upper end periphery of connecting pipe clamps the metal clamp, the slotted hole has been seted up on the connecting pipe, processing has four to stretch into the inside kink of connecting pipe from the slotted hole on the metal clamp, and the bottom processing of every slotted hole has the breach, the processing of the upper portion periphery of hush pipe has the epirelief platform, go up the processing seal groove of using on the boss, connecting pipe inner circle processing has the insertion the bead that the seal groove set up, the hole of making an uproar falls in a plurality of circular of the same size is seted up to the periphery of hush pipe, the processing of the lower part periphery of hush pipe has the lower boss, the bottom welding of.

Compared with the prior art, the utility model has the advantages that the hole site arrangement can be more flexibly designed according to the needs by adopting the round holes with the same size, thereby solving the ventilation efficiency of the same space; the circular port can adopt the insert pin structure of the same specification to carry out mould processing to the size of a dimension of having guaranteed each functional hole is unanimous, makes the amortization more superior, has improved noise reduction. The utility model discloses can be used to among the car turbo charger.

As the utility model discloses a further inject, the periphery processing multichannel cavity division board of hush pipe, the laminating of cavity division board sets up inside the connecting pipe. The chamber division board can be divided into a plurality of chambers between hush pipe and the connecting pipe to strengthen its noise reduction effect.

In order to enhance the sealing performance of the connection of the connecting pipe and the turbocharger, a sealing ring is arranged on the inner wall of the connecting pipe.

In order to further enhance the sealing performance of the connection of the connecting pipe and the turbocharger, two sealing surfaces are processed on the inner ring of the sealing ring.
