Abstract
The utility model relates to an exhaust pipe for motorcycle engines, which comprises an inner pipe and an outer pipe, the inner pipe is positioned in the outer pipe, both ends of the inner pipe are welded with both ends of the outer pipe, a closed cavity is formed between the inner pipe and the outer pipe, and heat-insulating material is filled in the cavity. The degree of the oxidation of the exhaust pipe by high-temperature tail gas can be decreased, and therefore, the appearance quality of the exhaust pipe is guaranteed.
Description
Technical field
The utility model relates to the outlet pipe of motorcycle engine, particularly is connected the engine exhaust pipe between engine exhaust port and the silencing apparatus.
Background technique
Have one section to be to be connected between engine exhaust port and the silencing apparatus in the outlet pipe of motorcycle engine, the waste gas of discharging through relief opening from engine chamber enters this section outlet pipe at first.The available engine outlet pipe is single layer structure, because the exhaust gas temperature of discharging from engine exhaust port is very high, so be easy to cause the oxidation of this section outlet pipe, causes the jaundice of this section outlet pipe surface, thereby influences the appearance quality of engine exhaust pipe.
Summary of the invention
The purpose of this utility model provides a kind of motorcycle engine outlet pipe, to guarantee the appearance quality of outlet pipe.
Motorcycle engine outlet pipe described in the utility model is made up of interior pipe and outer tube, and interior pipe is positioned at outer tube, and weld with the outer tube two ends respectively at its two ends, forms near closed hollow ring between interior pipe and outer tube, is filled with thermal-protective material in this die cavity.
The utility model is owing to have this kind structure, the high-temp waste gas of discharging from engine chamber is by passing through the interior pipe, directly do not contact with outer tube, the heat-blocking action of thermal-protective material in addition, the former temperature of outer tube that makes will be well below the temperature of interior pipe, thereby reduced the degree of oxidation of outer tube, guaranteed the appearance quality of outlet pipe.
Description of drawings
Now in conjunction with the accompanying drawings the utility model is described in further detail.
Fig. 1 is the main pseudosection of motorcycle engine outlet pipe described in the utility model.
Embodiment
As shown in Figure 1, this motorcycle engine outlet pipe is made up of interior pipe 3 and outer tube 1, and interior pipe 3 is positioned at outer tube 1, and weld with outer tube 1 two ends respectively at its two ends, forms near closed hollow ring between interior pipe 3 and outer tube 1, is filled with thermal-protective material 2 in this die cavity.
Claims (1)
1. motorcycle engine outlet pipe, it is characterized in that: be made up of interior pipe (3) and outer tube (1), interior pipe is positioned at outer tube, and weld with the outer tube two ends respectively at its two ends, between interior pipe and outer tube, form near closed hollow ring, in this die cavity, be filled with thermal-protective material (2).
