Description

new car exhaust pipe

technical field

The utility model belongs to the technical field of automobile accessories and relates to a novel automobile exhaust pipe.

Background technique

The exhaust pipe is a very common exhaust component on the car. Its air inlet is connected with the gas exhausted from the engine and discharged from the outlet of the exhaust pipe. The air outlet of the existing automobile exhaust pipe is generally open. When the rear-end wind is relatively large, especially when the automobile is running in a place with relatively large wind and sand, wind and sand may flow back into the exhaust pipe, thereby causing damage to the engine. damage, and even affect the performance of the entire vehicle.

In addition, the number of automobiles has increased rapidly in recent years, and the accompanying traffic noise pollution has become increasingly prominent. And the most important noise of automobile comes from the exhaust system of automobile, i.e. the noise of automobile exhaust emission. Existing automobile exhaust pipe realizes the effect of reducing noise by installing silencer, but the structure of silencer is complex and inconvenient to install.

Contents of the invention

The purpose of the utility model is to solve the above-mentioned problems in the existing technology, and propose a new type of automobile exhaust pipe with low production cost, which can prevent wind and sand from pouring into the exhaust pipe and reduce the noise generated when the automobile exhausts exhaust gas.

The purpose of this utility model can be achieved through the following technical proposals: a new type of automobile exhaust pipe, including two symmetrically arranged exhaust main pipes with exhaust passages, characterized in that the middle parts of the two exhaust main pipes are provided with two And the connecting pipe that connects the two, the inlet end of each exhaust main pipe is bifurcated and provided with two air intake branch pipes, and the outlet end of each exhaust main pipe is bifurcated and provided with two outlet branch pipes, each outlet Conical dust covers with windshield edges are installed at the outlet ends of branch pipes.

In the initial state of the new automobile exhaust pipe, the two exhaust main pipes are connected together through a connecting pipe, and a dust cover is installed at the outlet end of the outlet branch pipe, which has a simple structure and low production cost. The air port is connected with the gas exhausted from the automobile engine, and it is discharged from the outlet of the outlet branch pipe. The inlet branch pipe and the outlet branch pipe play the role of diversion, avoiding the concentrated emission of automobile exhaust, so it can reduce the generation of automobile exhaust. In addition, when the car is driving in a place with strong wind and sand, the dust cover can block the tail wind and prevent the wind and sand from pouring into the exhaust pipe.

In the above-mentioned novel automobile exhaust pipe, fixed rods arranged radially are installed around the gas outlet end of each outlet branch pipe, and the above-mentioned dust cover is fixedly installed on the outlet branch pipe through the fixed rods.

In the above-mentioned novel automobile exhaust pipe, the connecting section between each outlet branch pipe and the middle part of the corresponding exhaust main pipe is a bent section. The bending section can buffer the automobile exhaust gas entering the exhaust main pipe, which is beneficial to reduce noise.

In the above-mentioned novel automobile exhaust pipe, a three-way catalytic converter is installed on each outlet pipe. The three-way catalytic converter has stable performance, reliable quality and long service life, which can effectively reduce the environmental pollution caused by automobile exhaust.

Compared with the prior art, the utility model has simple structure and low production cost. The air intake branch pipe has an air inlet, and the air inlet port is connected with the gas discharged from the automobile engine, and is discharged from the air outlet of the air outlet branch pipe. Both the exhaust branch pipe and the exhaust branch pipe play the role of diversion, avoiding the concentrated emission of automobile exhaust, so the noise generated when the automobile exhausts exhaust can be reduced. In addition, when the automobile is driving in a place with strong wind and sand, the dust cover can block the tailwind It can prevent wind and sand from pouring into the exhaust pipe.

Detailed ways

The following are specific embodiments of the utility model and in conjunction with the accompanying drawings, the technical solution of the utility model is further described, but the utility model is not limited to these embodiments.

As shown in Figure 1, the novel automobile exhaust pipe includes two symmetrically arranged exhaust main pipes 1 with exhaust passages. The air intake ends of each exhaust main pipe 1 are bifurcated and provided with two air intake branch pipes 11, and the gas outlet ends of each exhaust main pipe 1 are bifurcated and provided with two air outlet branch pipes 12. All are equipped with a windshield edge and conical dust cover 4.

The periphery of the air outlet end of each air outlet branch pipe 12 is equipped with fixed rods 3 arranged radially, and the dust cover 4 is fixedly installed on the air outlet branch pipe 12 through the fixed rods 3 .

The connection section between each outlet branch pipe 12 and the middle part of the corresponding exhaust main pipe 1 is a bent section 13 . The bending section 13 can buffer the automobile exhaust gas entering the exhaust main pipe 1, which is beneficial to reduce noise.

A three-way catalytic converter 5 is installed on each outlet branch pipe 12 . The three-way catalytic converter 5 has stable performance, reliable quality and long service life, and can effectively reduce environmental pollution caused by automobile exhaust.

In the initial state of the new automobile exhaust pipe, two exhaust main pipes 1 are connected together through the connecting pipe 2, and a dust cover 4 is installed at the outlet end of the air outlet branch pipe 12. The structure is simple and the production cost is low. The intake branch pipe 11 has The air inlet, the air inlet is connected to the gas discharged from the automobile engine, and is discharged from the air outlet of the air outlet branch pipe 12. The air inlet branch pipes 11 and the air outlet branch pipes 12 all play the role of diversion, avoiding the concentrated emission of automobile exhaust. Therefore, the noise generated when the automobile discharges exhaust can be reduced. In addition, when the automobile is running in a place where wind and sand are relatively large, the dust cover 4 can block the rear-end wind and prevent the occurrence of wind and sand pouring into the exhaust pipe.

The specific embodiments described herein are only examples to illustrate the spirit of the present invention. Those skilled in the technical field to which the utility model belongs can make various modifications or supplements to the described specific embodiments or adopt similar methods to replace them, but they will not deviate from the spirit of the utility model or go beyond the appended claims defined range.
