Abstract
The utility model discloses an automatic oxygen-feeding unit used on vehicle or motorcycle exhaust emission, comprising an exhaust emission tube and a muffle. A liner, the diameter of which is gradually reduced, is integrated on the back end of the exhaust emission tube; a working tube is arranged outside of the liner; a fixing tube is arranged outside of the working tube; one end of each working tube and fixing tube is fixed on the external diameter of the back end of the exhaust emission tube; an oxygen-feeding hole is arranged on the working tube and communicated with the oxygen feeding tube and gets through the wall of the fixing tube for communicating the external air. The utility model has the advantages of reasonable design, simple structure, stable and reliable performance; meanwhile the vehicle or motorbike exhaust emission standard is effectively improved.
Description
Technical field
The utility model relates to the gas emission device of a kind of automobile, motorcycle, and particularly a kind of automobile, motorcycle exhaust discharge automatic oxygen supply device.
Background technique
At present, the automobile that uses in market sale and routine work, the life, motorcycle since during cylinder operation fuel combustion insufficient, do not purify mechanism on the gas emission device in addition, cause institute's discharge tail gas to exceed emission standard, environment is polluted.
The model utility content
The purpose of this utility model is the deficiency that exists at prior art, and the automobile, the motorcycle exhaust that a kind of reasonable in design, simple in structure, reliable working performance are provided and can effectively improve exhaust emission standard discharge automatic oxygen supply device.
The technical solution of the utility model is: a kind of automobile, motorcycle exhaust discharge automatic oxygen supply device, comprise tail gas discharging pipe 1 and baffler 7, it is characterized in that: the rear end of described tail gas discharging pipe 1 and its one are provided with the diminishing tail pipe 2 of diameter, the arranged outside of described tail pipe 2 has working pipe 3, the arranged outside of described working pipe 3 has fixed tube 5, and an end of working pipe 3 and fixed tube 5 is fixedly connected on respectively on the cylindrical of tail gas discharging pipe 1 rear end; Working pipe 3 is provided with oxygenating hole 4, and oxygenating hole 4 is communicated with outside atmosphere by the tube wall that the oxygenating pipe 6 that is communicated with it passes fixed tube 5, constitutes oxygenating passage 8 between working pipe 3 and the tail pipe 2.
The utility model compared with prior art has the following advantages: the utility model is reasonable in design, simple in structure, reliable working performance, can effectively improve the exhaust emission standard of automobile and motorcycle.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
The utility model will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, the utility model comprises tail gas discharging pipe 1 and baffler 7; The rear end of described tail gas discharging pipe 1 and its one are provided with the diminishing tail pipe 2 of diameter, the arranged outside of described tail pipe 2 has working pipe 3, the arranged outside of described working pipe 3 has fixed tube 5, and the front end of working pipe 3 and fixed tube 5 is fixedly connected on respectively on the cylindrical of tail gas discharging pipe 1 rear end; Working pipe 3 is provided with oxygenating hole 4, and oxygenating hole 4 is communicated with outside atmosphere by the tube wall that the oxygenating pipe 6 that is communicated with it passes fixed tube 5, constitutes oxygenating passage 8 between working pipe 3 and the tail pipe 2.
Described tail gas discharging pipe 1, tail pipe 2, working pipe 3 and fixed tube 5 are arranged on same the axis; Described baffler 7 is arranged in the tube chamber of fixed tube 5 afterbodys.
The utility model working principle: when automobile or motorcycle engine work, tail gas is discharged through tail gas discharging pipe 1, when through the diminishing tail pipe 2 of diameter, the tail gas flow velocity is accelerated, make to form negative pressure in the oxygenating passage 8, thereby will contain the oxygen air in a large number by mixing in the 4 suction oxygenating passages 8 of oxygenating hole and with the tail gas of tail pipe 2 discharges.
