Abstract
The utility model provides an energy-saving guiding tail pipe to accelerate the discharging of the waste gas when the engine is running up, which is comprised of a connector, a prepositive guide plate, a casing, an inner pipe with a vent and a bearing score nozzle. A guide pipe which is coaxial with the inner pipe but the diameter of which is less than that of the inner pipe is sleeved at the end of the inner pipe. A postpositive guide plate which is vertical to the shaft axis is arranged on the guide plate, the other end of which is fixed on the bearing score nozzle. When the automobile is running at a high speed, the engine is running up, and then a subpressure is formed, part of the waste gas will be discharged through the vent quickly, and then jet out of the Bearing score nozzle along the postpositive guide plate; another part of the waste gas will jet out of the Bearing score nozzle through the guide pipe. The utility model has increased the exhausting speed, made the engine more powerful through making the fuel fully burnt and realized energy-saving.
Description
Technical field
The utility model relates to a kind of automobile and is used for the tailpipe of discharging waste gas.
Background technique
Air displacement is one of leading indicator of car engine ability, because in order to reduce the pollution that noise reduces waste gas, install muffler tail pipe additional, tailpipe is mostly again to be single pipes, increased resistance to engine exhaust, therefore, waste gas in time can not have been discharged during engine fast turn-around, cause burning insufficient, the index of engine ability is descended greatly.
Summary of the invention
When providing a kind of engine fast turn-around, goal of the invention of the present utility model can quicken the flow guide type energy-saving tailed-gas exhaust pipe that waste gas is discharged, this flow guide type energy-saving tailed-gas exhaust pipe includes connection mouth, preposition guide plate, shell, the interior pipe and the Laval nozzle that have exhaust port constitute, the air intlet of shell front end is horn-like, and air intlet and shell are at an angle, in in the pipe tail end cover one with interior pipe coaxial and diameter less than the honeycomb duct of interior pipe, honeycomb duct is provided with the rearmounted guide plate vertical with shaft axis, the other end of rearmounted guide plate is fixed on the Laval nozzle, and the number of rearmounted guide plate is advisable with three.During galloping, engine then runs up, on the transition-cone passage between interior pipe and the Laval nozzle, form negative pressure, interior pipe pressure inside is greater than the outside, partly waste gas is just discharged rapidly by exhaust port, by the ejection of Laval nozzle puff prot, another part waste gas is sprayed by the Laval nozzle puff prot through honeycomb duct along rearmounted guide plate.The effect of honeycomb duct and guide plate is that waste gas is derived in order, prevents to produce sinuous flow, improves exhaust velocity.When engine idling or low-speed running, negative pressure disappears, and replys the resistance of outlet pipe, keeps the stable of engine torque.
The utility model can be directly by dress when automobile production, also can be as the auxiliary accessories add-assembly, connection mouth is enclosed within on the automobile exhaust tail pipe with pipe collar is fixing gets final product, simple in structure, convenient by dress, promptly reduce pollution to air, can make full combustion of fuel again, improve engine's motive power, energy-conserving and environment-protective, easy to utilize.
Description of drawings
Fig. 1, structural representation of the present utility model;
The structural representation of honeycomb duct in Fig. 2, the utility model;
The angle schematic representation of air intlet and shell in Fig. 3, the utility model.
Among the figure, 1, connection mouth, 2, Laval nozzle, 3, air intlet, 4, preposition guide plate, 5, shell, 6, interior pipe, 7, exhaust port, 8, honeycomb duct, 9, rearmounted guide plate, 10, puff prot, a is an air intlet 3 and the tapering angle of shell 5.
Embodiment
As seen from the figure, the utility model includes connection mouth 1, Laval nozzle 2, air intlet 3, preposition guide plate 4, shell 5, interior pipe 6 and exhaust port 7 and constitutes, feature be in the tail end of interior pipe 6 coaxial the and diameter of cover one and interior pipe 6 less than the honeycomb duct 8 of interior pipe 6, honeycomb duct 8 is provided with the rearmounted guide plate 9 vertical with shaft axis, the other end of rearmounted guide plate 9 is fixed on the Laval nozzle 2, the number of rearmounted guide plate 9 can adopt three, in addition, air intlet 3 is big I selection in 15 degree plus-minuss, 1 degree of the tapering angle a of horn-like and shell 5.
Working principle of the present utility model is: during galloping, engine then runs up, on the transition-cone passage between interior pipe 6 and the Laval nozzle 2, form negative pressure, interior pipe 6 pressure inside are greater than the outside, partly waste gas is just discharged rapidly by exhaust port 7, along puff prot 10 ejections of rearmounted guide plate 9 by Laval nozzle 2, another part waste gas is through puff prot 10 ejections of honeycomb duct 8 by Laval nozzle 2.The effect of honeycomb duct 8 and rearmounted guide plate 9 is that waste gas is discharged in order, prevents to produce sinuous flow, improves exhaust velocity.When engine idling or low-speed running, negative pressure disappears, and replys the resistance of outlet pipe, keeps the stable of engine torque.
