Abstract
The utility model discloses an exhaust connecting pipe device for a commercial vehicle engine. The exhaust connecting pipe device for the commercial vehicle engine comprises an exhaust pipe connected with an exhaust manifold of the commercial vehicle engine. The gas outlet end of the exhaust pipe is hermetically connected with the gas inlet end of a gas distribution chamber; the gas outlet end of the gas distribution chamber is provided with two gas outlets; the two gas outlets are respectively provided with a gas outlet pipe; both end parts of the gas distribution chamber are respectively provided with a connecting choke; the two gas outlets are symmetrically distributed on the side walls of the connecting chokes; a silencer and an exhaust filter unit are also arranged in the gas distribution chamber; the pressure of exhausted gas can be reduced by the gas distribution chamber, and further, the impact of exhaust to the two gas outlet pipes is reduced, and moreover, the silencer is also arranged in the gas distribution chamber to eliminate exhaust noise, hazardous substances of the exhaust gas can be filtered by the exhaust filter unit, and therefore, an environmental protection effect is further improved, so that the use of the exhaust connecting pipe device is safer and more stable.
Description
Technical field
The utility model relates to a kind of commercial car field, relates in particular to the exhaust connection device that a kind of commercial vehicle engine uses.
Background technique
The vent systems of commercial car refers to collect and the system of discharging waste gas, and it mainly acts on the waste gas that produces when being the discharging engine operation, and the exhaust emission pollution of discharge is reduced, and noise reduces.But automobile worsens automotive performance in use owing to the fault of oil supply system, ignition system etc. in the prior art, causes situations such as power performance decline, fuel consume increase, deterioration of emission.
In the actual exhaust air process, the part commercial car has also adopted the twin exhaust pipes mode to carry out exhaust, therefore can produce certain noise, and gas can be unfavorable for the long-term stable operation of outlet pipe to the bigger impact dynamics of outlet end generation of two outlet pipes.
The model utility content
The technical problems to be solved in the utility model provides a kind of commercial vehicle engine exhaust connection device of simple in structure, clean environmental protection.
For addressing the above problem, the utility model adopts following technological scheme: commercial vehicle engine exhaust connection device, comprise the outlet pipe that is connected with the commercial vehicle engine gas exhaust manifold, the outlet side of described outlet pipe is sealedly connected on the inlet end of sub-air chamber, the outlet side of described sub-air chamber is provided with two air outlets, is separately installed with steam outlet pipe on the two described air outlets; Described sub-air chamber two end part are provided with the connection reducing respectively, and two described air outlets are symmetrically distributed on the sidewall of described connection reducing, also are provided with silencer and exhaust and filtration apparatus in the described sub-air chamber.
As a kind of improvement, described silencer is included in the noise reduction net that described sub-air chamber inwall is provided with.
As a kind of improvement, described exhaust and filtration apparatus comprises the smoke filtration core that is installed in the described sub-air chamber.
Owing to adopted such scheme, commercial vehicle engine exhaust connection device, comprise the outlet pipe that is connected with the commercial vehicle engine gas exhaust manifold, the outlet side of described outlet pipe is sealedly connected on the inlet end of sub-air chamber, the outlet side of described sub-air chamber is provided with two air outlets, is separately installed with steam outlet pipe on the two described air outlets; Described sub-air chamber two end part are provided with the connection reducing respectively, and two described air outlets are symmetrically distributed on the sidewall of described connection reducing, also are provided with silencer and exhaust and filtration apparatus in the described sub-air chamber; The beneficial effects of the utility model are: sub-air chamber can reduce the pressure of the gas of discharging, and then reduce exhaust to the impact of two steam outlet pipes, and in sub-air chamber, also be provided with silencer, eliminate exhaust noise, exhaust and filtration apparatus can filter the harmful matter of waste gas, thereby further improved environment protection effect, made exhaust pipe device use safety and stability more.
Description of drawings
In order to be easy to explanation, the utility model is done to describe in detail by following specific embodiment and accompanying drawing.
Fig. 1 is the utility model embodiment's structural representation;
Wherein: the 1-outlet pipe; 2-sub-air chamber; 21-connects reducing; The 3-steam outlet pipe; 4-noise reduction net; 5-smoke filtration core.
Embodiment
As shown in Figure 1, commercial vehicle engine exhaust connection device, comprise the outlet pipe 1 that is connected with the commercial vehicle engine gas exhaust manifold, the outlet side of described outlet pipe 1 is sealedly connected on the inlet end of sub-air chamber 2, the outlet side of described sub-air chamber 2 is provided with two air outlets, is separately installed with steam outlet pipe 3 on the two described air outlets; Described sub-air chamber 2 two end part are provided with connection reducing 21, two described air outlets respectively and are symmetrically distributed on the sidewall of described connection reducing 21, also are provided with silencer and exhaust and filtration apparatus in the described sub-air chamber 2.
Described silencer is included in the noise reduction net 4 that described sub-air chamber 2 inwalls are provided with.
Described exhaust and filtration apparatus comprises the smoke filtration core 5 that is installed in the described sub-air chamber 2.
Sub-air chamber of the present utility model can reduce the pressure of the gas of discharging, and then reduces exhaust to the impact of two steam outlet pipes, thereby has protected two steam outlet pipes, has prolonged its working life.And in sub-air chamber, also be provided with silencer, eliminate exhaust noise, prevent from producing too much noise in the commercial vehicle running process, thereby eliminated noise pollution.Exhaust and filtration apparatus can filter the harmful matter of waste gas, thereby has further improved environment protection effect, prevents the much and befouling environment of discharge amount of exhaust gas.
